Wait, dieing in one turn against Carnifex sounds ridiculous. So in 1 turn he gets to close all the distance and kill you? Dex based with steel gloves..like 7 attacks per turn, raw 150 dmg each?
Quite a bit more than 150, he also will entangle (he throws nets) and debuff you with yell. He also has a chance to incapacitate you. He also has 700 health and pretty high dodge/evasion. You don't get to be a legendary champion of the Arena by collecting coupons, you know) Overall he can do what a optimized unarmed build can.
From what I read, he's mechanical melee dmg, in that case shield only blocks 20% of its normal capacity. Then I am wondering..even if I wear Infused Ancient rathound leather & metal boots & helmet I die? wow that's insane.
Less. Combat gloves ignore 80% of your shield additionally. For the most part, shield will do close to nothing against melee opponents. Depending on the quality of the leather and components, you maybe has a small chance of surviving first round.
Besides, if my initiative is 17 (+1 dex) and his is 29, and roll is -+15, that leaves me with -12, so I win 3/15 of the times and he 11/15 (tie 1/15), meaning ~20% chance for me to start? Dunno if I got it right.
You have to refresh you memory on how probabilities actually work, mate) You have 1.33% chance of winning the initiative with additional +1 dex. You have to roll at least 14 while he has to roll no higher than 3 (a bit more complex in actual equation, i'm simplifying here) at the same time. Also, i think he wins on tie since he got higher base bonus, but i'm not sure about that. If he doesn't, you get 2.66% of winning initiative.
At this point, this build offers little variation, except for additionally sacrifying 2 points of Per into Con (+50HP). This made me even more interested in playing it hehe
Mate, you are still squishy as hell, and he still gonna kill you in one round, most probably. You also reduced your chances of hitting stuff and damage you are gonna deal. At which point you are better playing regular psion.
Also, i already gave you an advice - take Paranoia feat. At the very least, you gonna have reasonable chances of winning initiative (1 in 11), meaning that you can actually have a drop on him and having less reload screens in total in your playthrough (way less).
You are not gonna enjoy it, really, unless you enjoy reloading every fight several times over. Build with no health, no armor, no evasion/dodge, no initiative and little to no stealth....well, you are in for a ride. I think you gonna drop this game way before even getting to Arena.
