Yes, I think hemopsichosis is good in this build, no use it before. Stealth enemy's no problem, because after entering in New area I use shield . With this build I make 3 attempt, finish depot , and most time after this I die after lose concentration, stealth enemy can not kill you in one round. Most time in danger situation, I lose 65%-70% health, after this
Use psionic mania, premeditation, one powerfull spell. Enables survival insincts, I use more spells , morfine, aegis and finish round.On next round I have near 20-30 %health after all damage i get and heal from regen vest and can cast
some more spells with high crit chance. And with hemopsichosis you can control your health more effectively, it's very good. On 3 round use last stand and fight again. If any alive after this you can use force wall and heal all health by regen vest , and fight again.
