Could you up the damage of Achemides II ? If it can only be used once a day, has its own quest and is a damn satalite laser, then it shouldbe able to kill anything in one hit. It just feels weird that it sometimes dosent kill. it wouldnt really be unbalenced due to one shot a day.

That perk requires 70! points in to barter ...which is generally pretty useless stat. At last compared to something like picklock or science.
