The player character in Star Wars: Knights of the Old Republic II: The Sith Lords can obtain thorium charges from Akkere through dialogue near the end of the Dantooine mission or by killing the merchant, and can find them on Korriban accompanied by a datapad highlighting their destructive nature. The charges are in a nearby footlocker, and if the player character chooses to \"bash open\" the footlocker instead of cracking its lock, the thorium charges detonate, causing damage to all party members nearby.
Killing Akkere is psychotic. If you already bought the thorium charges, then you receive the 1000 credits you paid for them instead. This quest can still be completed after the Battle of Khoonda, but only if Akkere survives (you must finalize battle plans with Zherron back in Khoonda, and fight Azkul and his mercenaries).
Master Vrook and Jorran cannot be killed, and any defense droids have Damage Resistance: Resist 15/- vs. Bludgeoning, Piercing and Slashing, and a Droid Unity Grid if you activated shields. If Akkere is killed, then you won't find thorium charges on his remains. 1e1e36bf2d
