If you invested more than that: lol noob! (j/k You'll get those back on the next level up (unless you're max level in which case: lol noob!))

Reckless players will still be able to alert entire floors, but playing with care will result in fighting smaller groups at a time, which also prevents pathfinding slowdowns Jookhela got a new coat of paint [Expedition] Minor tweaks to Ray's Shop as to prevent a few camera vision exploits [Expedition] Dude will now make you another Juice in case you waste the first one. [Expedition] He'll also take hydraulic fluid from DC instead of a certain gun lube (as they're both mineral oil-based). [Expedition] ...and he accepts mushroom brew as currency following a certain event.

Underrail 1.1.2

Release Date: 21 July 2020

Summary: Waterways and Psi Update

General Improved the start up time for the game Initimidation now scales off either Strength or Will (whichever is higher) [Expedition] Halved the cost of most jet ski frames, engines, batteries and suspensions [Expedition] Increased the damage of all jet ski weapon attacks Psi You now have to "innervate" psi abilities that you plan to use and you're limited in the number of innervated psi slots (1 + 1 per 3 intelligence, up to maximum of 6). Existing psi characters can use Will stat instead for the number of slots with some downsides, or they can opt to switch to Int by consuming a pill that's been subtly slipped into their pockets. Introduced psi reserves, which is the long term psi resource that does not regenerate naturally, but through the usage of psi inhalant which can not be done in combat. Psi reserves are depleted when you regenerate psi naturally or through psi boosters. Maximum amount of psi reserves is equal to 5 times the maximum psi points. Psi inhalant is craftable with some skill in biology and chemistry. All existing player characters will get generous amount of psi inhalants first time you load the game in new version Upon loading the game for the first time in the new version, a random set of psi abilities will be pre-innervated for you. If you don't like the random selection, just reload the same save. Psi Abilities Force Field psi cost changed to 40 (up from 25) Force Field is now destructable and has its health points scale with invoker's skill. Each segment of the force field has separate health, but destroying one will destroy all of them. Thermodynamic Destabilization base damage percentage changed to 30% (down from 50%) and it now scales by 0.5% (down from 1%) per skill point and is capped at 100%. Thermodynamic Destabilization action point cost changed to 10 (down from 20) Enrage maximum duration changed to 2 (down from 4) Increased the amount of damage of Neural Overload and Psi-cognitive Interruption blocked by resolve Added psi mentors for all psionic abilities in the game (except one) to the random loot table [Expedition] Psycho-temporal dilation and Limited temporal increment learning requirements swapped to their correct positions [Expedition] Psycho-temporal contraction now has a high chance of causing its opposite (with randomized power) when it expires Items Biohazard suit now provides full protection from a certain very, very bad gas Spearhead sniper rifles will now have base action points of 32 (up from 30) Rapid Reloader firearm enhancement will now also have a 25% chance of restoring a random amount of action points ranging from 50% to 100% of the base action point cost of the weapon (but capped at 20ap); this can only trigger once per turn Dragunov now costs 30 ap to fire (up from 25) and has 60% chance to restore 10-20 ap once per turn; also has slightly increased damage Added shiv blueprint [Expedition] Psionic Accelerator now increases psi regeneration by 50% (up from 20%) [Expedition] Added Kzozel Yantar, a stronger version of Kzozel Creatures Reduced the throwing precision of hunchback mutants Mutant dog's acid blob attack will now deal some of its damage directly Quests / Areas Added a mercantile check when paying to use the Wormhole Silas' death will no longer fail the attack on Scrapper base quest; the player can now speak with Colton to get the reward instead Added shiv components to certain encounters in which the player loses his inventory Added new graphics for a few secret cave doors [Expedition] Added more content for the waterways - one big new dungeon, a couple of smaller locations, many new random encounters and other stuff [Expedition] Added some new ways to escape from a jail guarded by a hefty knife thrower [Expedition] Added a vending machine to the Gray Army base; it accepts zlatortiyas only [Expedition] In the same base, it is now possible to translate messages on one of the computers with sufficient intelligence [Expedition] Added a tool with which the player can repair/configure a certain camp defense asset; found in multiple locations in the Black Sea Visual You can now zoom the game in by holding shift while scrolling the mouse button, but the feature needs to be enabled in the options first High explosive and frag greandes and mines now have new visual effects UI Made a new death screen that will allow you to scroll through the combat log to see exactly what killed you if you didn't catch it during combat Fixed the scroll bars so they can be mouse scrolled when moused over Feats Locus Of Control - Change AoE radius to 2 (down from 3) Force User - now also increases health of force field by 50% (plus 5% per spec, max 5 spec points) Critical Power - Base bonus changed to 1% (down from 1.5%) and spec bonus changed to 0.1% (down from 0.15%); I'm not happy with this feat in general. Straight unconditional passive damage boost feats is something I'm going to avoid in the future for sure Tweaks Acid pistols (and other acid attacks) will now spill acid on the ground regardless of whether they hit the primary target or not Certain random encounters will no longer appear in low-level zones (Arsonist in early under-passages, rabid dogs in Crossroad Caves, etc.) Balor now has Sprint, and gets an adrenaline shot on higher difficulties Cliff can now be given a coagulation shot to stop him from bleeding to death Kareem now needs his "memory refreshed" when asked about certain things The Black Eels questline can now be started after you've found the drill rotor circuit board Halved the amount of money Mykola needs to repair one big machine from 2000 to 1000 charons Some dialogs tweaked to reflect the new psi changes Bugs Fixed the bug that cause the energy shield to dissipate at 2% instead of the nominal 10% rate every turn, but I set it to 5% base now instead because 10% just seems a bit too severe to me now; also changed the minimal dissipation rate to 1.5% (down from 2%) Explosive barrels and various misc. explosions should now properly trigger volatile entities such as mines Throwable barrels and rocks will now behave properly when throw in water (they will not detonate on impact) You can no longer double-click while holding a modifier key (shift, alt, or ctrl). This is to prevent situations such as rapdily alt-left clicking to transfer items from a container from also triggering the double-click event and transfering extra items. Let me know if this causes any anomalous behavior. Sledgehammer and machete handle now also count as metal components like knife one Fixed the bug that would cause the caster tentacles to crash the game after the player dies or disengages Ranged weapon innate precision modifier will now always be if it's negative Fixed Gorsky's base not being renovated on easy difficulty Fixed sometimes not getting a quest note (and subsequent xp once it's completed) from Kohlmeier when starting his quest Fixed traps not despawning after Foundry mines have been cleared, which resulted in hostile miners Fixed spears and nets not appearing in the loot locker in the Arena Fixed Saban not properly receiving his spare W2C ammo [Expedition] Fixed JSHQ bioscan not detecting mutagens [Expedition] Fixed an entrance to a cave near a certain homestead being impassable, even if discovered [Expedition] Fixed an important flag not being set when going through some branches during a discussion about a truly deathly topic with the Ferryman [Expedition] Fixed electrified floor destroying auto-turrets in Water Treatment Facility in one of the variations; also added a sound effect during discharge as to give the player a warning [Expedition] Fixed a bug where sleeping in the camp (and under very specific circumstances) triggering a certain crucial event even if the player, paradoxically, already prevented its occurence [Expedition] Fixed the final quest note prematurely being marked as completed [Expedition] Fixed a crash that may occur if the player obtains some floaty things for the camp too early [Expedition] Fixed certain native weapons being non-equippable [Expedition] Fixed Captain Grim sometimes ending dialog when telling him about some facilities [Expedition] Fixed being able to sleep in the camp even after you got fired [Expedition] Fixed the bug that caused players to get stuck on some hives after destroying them.

Underrail 1.1.0

Release Date: 9 July 2019 (experimental branch)

Summary: Game speedup, mechanics/item tweaks, graphics updates, bugfixes

General Added the ability to speed up the game while out of combat Added achievements to the GOG Galaxy version Feats Kneecap shot bleeding percentage no longer scales from perception, but base bleeding damage percentage changed to 125% (up from 75%) New feat: Improved Unarmed Combat Mechanics Unarmed and fist weapon attacks now incur 140% of target's damage threshold and resistance (up from 125%) Increased the damage reduction factor of resolve against neural overload Resolve will now reduce the damage received from doppelgangers Changed the way the burning damage stacks (in cases when it stacks) - the new burning time left equals either the time left of the existing effect or the duration of the new effect - whichever is longer; the old and the new periodic damage are adjusted so that they produce the same total damage over time; one of the major effects of this change is that you can no longer increase the amount of original damage by constantly resetting the timer Separated fear effect caused by burning into a separate status effect and limited it to 2 turns regardless of how long the burning lasts (or if it's extinguished early); this will prevent the fear from lasting too long either from a long burning effect or because of the burning effect being refreshed; also this fear only occurs when a non-burning target is ignited and not when burning is being prolonged/refreshed Items Throwing nets now last up to 2 turns (down from 3) and have a cooldown of 4 turns (up from 3) Bullets have new icons Increased the chance to entangle enemies when firing acid blob pistol Increased the chance to freeze enemies when firing cryo blob pistols Reduced the chance to ignite enemies when firing incendiary blob pistol; the total burning damage done from igniting the target will remain the same, but will be spread over more turns (one turn per each 80% of the original damage repeated) Reduced the weight of chemical ammo Nice Things Containers that you opened once will now have darker labels Organic enemies that die while burning will now be smoking and appear charred HE grenades and some other explosions will leave temporary marks on the ground Gas clouds will now fade in/out New barrels Bugs Fixed the bug that would allow player to cancel leveling up without being able to reattempt it Fixed the problem that caused the items to take up weird positions in the filtered inventory when the player attempted to reorder them manually Cut Throat no longer bypasses stun immunities Corporeal Projection feat now has a proper icon (instead of using the one from Fast Metabolism) Throwing knife will now again properly play impact sounds and effects Fixed the bug that caused expertise to add the damage bonus for each separate mechanical damage listed for the weapon, instead of just once (you thought I'd never find out, did you?!) Fixed the hole jump crash in Institute Heavyweight will now always apply before Critical Power Certain giant appendages can now be hit by cryokinetic orb Changed the way the cryokinetic orb shards interact with the orb impact tile so now the creatures occupying the tile can also get hit by some of them Punching bags will no longer bleed when you punch them Global entities (those that can travel between maps) will now also have their suspicion meter drain with time Incendiary chemical pistol burning effect will now stack damage with existing burning effect Fixed the Nimble bug that would in certain situation give bonus movement points Various minor map and dialog bugs
