This page explains statistics seen in the Combat Stats C menu and certain other statistics that aren't listed anywhere.
Combat Stats: Base
State
- Health
- Shows current and maximum health points. When your current health point reach zero, you die.
- Derived from character level and Constitution. Can be affected by feats and items. Player character has 50% bonus health. If playing on easy/hard difficulty, player health is roughly doubled/halved. (The extra health received assumes player has average Constitution.)
- Shield
- Shows current and maximum shield points. Whenever you're hit, the shield will absorb certain amount of damage depending on the impact speed of the attack as long as you have shield points lefts. Shields will also slowly deplete on their own while turned on.
- Only shows up when you have a Shield Emitter equipped.
- Psi
- Shows current and maximum psi points, as well as psi regeneration per turn. Psi is used to invoke psionic abilities.
- Starts at 100. No longer derived from character level and Will as of version 0.1.14.0, but can be affected by feats and items.
Base Abilities
- Main article: Base Abilities
Your effective base ability scores are listed in the combat stats menu. Any bonuses and penalties you may have to their base values are included in these scores.
- Strength
- Strength measures your character's muscle power. It affects melee damage and carry capacity. It's also important for characters who intend to use heavier weapons (such as sniper and assault rifles and sledgehammers).
- Dexterity
- Dexterity measures character's reflexes, hand-eye coordination and finger nimbleness. It affects many things, such as operating locks, thievery, throwing and initiative. It increases critical strike chance of melee attacks. High dexterity also reduces action point cost of unarmed and light weapons (pistols, SMGs, knives, throwing knives and fist weapons)
- Agility
- Agility represents character's reflexes, fleet-footedness, jumping ability, as well as affinity towards other athletic and acrobatic activities. Among other things it affects dodge, evasion, initiative and movement points. It also allows the character to move more quietly, increasing the stealth performance.
- Constitution
- Constitution represents the health and general stamina of your character. It is important for all types of characters, but especially for those who plan on making the armor suit their main defense. It also helps prevent or lessen the effects of poisons and diseases.
- Perception
- Perception represents character's ability to discern objects from far away as well as to notice hidden things in their vicinity. It helps the character to use ranged weapons more effectively, as well as detect hidden objects, passages and creatures.
- Will
- Will measures your character's mental determination to see to his action regardless of various mental difficulties, such as pain, suggestion and overwhelming odds, as well as to force his will onto others and the environment. It heavily affects all psi disciplines as well as psi point regeneration.
- Intelligence
- Intelligence determines how well the character learns and reasons. It is important for a character that focuses on science as all disciplines are dependent on it. It also affects psi point regeneration.
Combat Stats: Defense
Defense
Attacks and status effects can be resisted (ie. completely avoided) with Dodge, Evasion, Fortitude and Resolve, depending on the attack's type.
These four defensive skills are checked against attacker's relevant skill, e.g. An attack with Frighten would test attacker's Thought Control vs. defender's Resolve.[1]
The chance to resist them this way is capped at 65%.[2]
- Dodge
- Increases your chance to avoid melee attacks.
- Equal to your effective Dodge skill. Can be affected by feats and items.
- Evasion
- Increases your chance to avoid ranged attacks and also decreases the damage taken from area of effect attacks.
- Equal to your effective Evasion skill. Can be affected by feats and items.
- Fortitude
- Increases the chance to resist some negative status effects, such as stun and incapacitation, caused by direct physical trauma.
- Derived from character level and Constitution (60%), Strength (20%) and Will (20%).
- Resolve
- Increases the chance to resist some negative status effects, such as stun and incapacitation, caused by mental stress and also reduces damage or duration of certain psionic attacks that target the mind directly.
- Derived from character level and Will. Can be affected by items and status effects.
- Crit. chance
- Modifies the chance you'll get critically hit with weapons and unarmed attacks.
- Can be affected by feats and items.
- Armor penalty
- Reduces dodge, evasion, stealth and movement points.
- Derived from the armor pieces you're wearing. Can be affected by feats. It is capped at 95%.[3]
Shielding
Energy shields can absorb certain amounts of damage based on the damage's impact speed. Slower impact speeds are generally better against energy shields.
Shield Capacity is the total amount of damage the shield can absorb when fully charged.
All damage sources have an Impact Speed, which is one of the following:
- Very Low — Melee attacks
- Low — Slow projectiles (considerably slower than bullets, such as crossbow bolts and cryokinesis)
- Medium — Bullets, shrapnel (from frag grenades/mines)
- Fast — Explosives, extremely fast projectiles (such as those fired from sniper rifles)
- Very Fast — Lasers, plasma, electrical attacks
Additionally, most light melee attacks will ignore certain amount of shield.
- 60% — Typical knives
- 80% — Typical fist weapons
- 100% — Unarmed
Resistances
All characters have Damage Resistance and Damage Threshold (DR% / DT) for each damage type, derived from their equipped and/or natural armor. Resistance is a percentage reduction, whilst threshold is a flat number reduction.
Only the greater of the two reductions will be applied against any one attack, not both.
The resistible damage types are Mechanical, Heat, Cold, Electricity, Acid, Energy and Bio.
Irresistible damage
Keep in mind that certain damages, such as poison or direct mind damage, completely ignore armor.
- The bio damage from poisons ignores armor (but the initial attack delivering poison must penetrate armor for the poison to take effect).
- Some thought control psi abilities deal irresistible mental damage.
- Bilocation
- Neural Overload damage is irresistible, but can be reduced by Resolve. Mitigation for this is capped at ~40%.
- Psi-cognitive Interruption
Subterfuge
- Stealth
- Indicates how well you can move undetected. The higher your stealth rating is in comparison to enemy's detection the longer it will take for you to be discovered. If your stealth is much too lower than the detection rating, you will be discovered instantly at maximum range.
- Equal to your effective Stealth skill. Can be affected by feats and items.
- Detection
- Indicates how quickly you discover hidden characters. Finding secret areas is based purely on Perception instead of Detection.
- Derived from character level and Perception. Can be affected by feats and items.
- Trap Detection
- Indicates how well you discover traps.
- Derived from detection rating and traps skill.

Unlisted statistics
These statistics aren't listed in the combat menu or any other menus.
Character level
|
This article is outdated. You can help Underrail Wiki by updating it. Reason given: XP charts from alpha version |
The maximum character level is 25. Prior to version 0.1.14.0, it was 20. In the release versions, there is no way to directly see NPC levels.
- Level does not directly affect most character's stats. Exceptions to this are health, fortitude, resolve and detection.
- Characters gain 40 skill points every level
- Characters gain a feat every 2 levels
- Characters gain a base ability point every 4 levels
- Fortitude, resolve and detection function like skills that get 4-5 points automatically invested into them each level. They get a bonus/penalty from their related base ability just like normal skills do.
- NPCs have natural dodge and evasion bonus equal to their level.
Classic XP SystemThe experience needed to level up is completely linear, each level requiring 1250 experience more than the former. Experience is gained from quest completion, kills, skill usage, finding secrets and oddities.
|
Oddity XP SystemThe experience needed to level up starts off completely linear with each level requiring 1 more experience than the former, but stops at 25 XP/level. Experience is gained only from oddities studied and quest completion.

Action and movement points
- All characters have 50 AP. They can be used for any action, including moving. Most actions consume AP, but there are exceptions. (e.g. Special Tactics)
- Wearing heavy armor without meeting its strength requirement will reduce action points.[4]
- AP can be temporarily increased or decreased. Debuffs cannot drop AP below 35.
- Character base movement points equal 30 + extra 3 points for every point in agility above 5. Movement points can only be used for moving.
- Movement points are affected by agility, armor penalty or bonus, encumberance and some feats.
- Some effects that change movement points also change real-time movement speed.
- Some creatures, such dogs and spawn, have natural bonus to movement points.
Precision
Precision or chance to hit determines chance of an attack hitting its target and the precision of area of effect attacks. It is based on attacker's weapon skill and a large number of other factors. Precision is calculated the same way for both the player character and all non-player characters. Your precision is displayed on the right side of the attack cursor.
- Base precision (with zero attack skill against zero defense skill and no other modifiers) is 70%.
- Precision limits are 10—95% for targeted attacks, 0—100% for AoE attacks (such as grenades).
- Area of effect attacks will always hit targets within their radius, but they can land up to 3 tiles away from targeted location.
- Most psi attacks always hit their target. However, Pyrokinesis is an AoE attack. Its precision is derived from Metathermics skill. Status effects caused by psi abilities can be resisted with Fortitude (physical effects) or Resolve (mental effects).
Modifiers
Precision is affected by many different modifiers, especially in ranged combat. Some precision penalties cannot be mitigated with weapon skill alone.
Skill
- Attack skill
- Increases precision. The main factor in precision calculation.
- Defense skill
- Dodge/evasion can reduce chance to hit by up to 60% (if evasion/dodge rating is twice the attacker's effective attack skill)[5]
- AoE attacks cannot be completely avoided with defense skill, but evasion decreases their damage.
Environment
Environmental modifiers affect chance to hit in ranged combat.
- Darkness
- Darkness plays a large role in ranged weapon precision. Most areas in Underrail are dark and the penalty is quite high at long ranges.
- Darkness penalty can be completely counteracted with Night Vision, or lowered with flares and/or other ambient light sources.
- Distance and optimal range
- Precision decreases with distance for all ranged weapons including AoE weapons.
- Precision further decreases beyond weapon's optimal range.
Weapon
Weapons can have additional modifiers to precision.
- Low durability
- Any Degraded Weapon or Heavily Degraded Weapon loses more precision the more degraded it is, all the way down to the minimal 10% chance to hit.
- Move and Shoot penalty
- Crossbows and rifles may have move penalty which decreases their precision if the user is not Focused. (Has moved during the current turn)
- Close Quarters penalty
- Crossbows and rifles may also have a precision penalty against foes at melee range. Close quarters penalty only applies In Combat against hostile targets.
- Strength requirement
- Rifles and sledgehammers have a strength requirement. Precision is decreased by about 10%Verify for each point of strength below the requirement.
- Other weapon modifiers
- Weapons may have attachments or other modifiers that change their base precision or burst precision.
