Speaking of grenades, this is my current draft of the "no crafting, no hacking/lockpicking/traps final destination" character as a variant of Pope Amole's psion build.
3-6-3-7-3-10-8
Skills (all max, all the time): Thought Control, Psychokinesis, Metathermics, Intimidate, Throwing, Dodge, Evasion, Pickpocket (maybe Persuasion instead of Pickpocket, but I really want to try it out)
Key feats: all relevant psi feats, Yell, Grenadier, Fast Metabolism, Deflection, Nimble
Unarmed (for Deflection), using grenades and misc throwing items (throwing knives only for poison utility, not damage) in quickslots. Light armor for Nimble except for specific heavy armor in Certain Plot Fights.
Are there any obvious flaws in this concept (and would it be possible to make a guns or melee psi hybrid without spreading attribute points too thin)? I'm not much of a theorycrafter.
