In the next version sneak-attack damage will be added to both melee and ranged physical attacks carried out by the player upon unaware foes.The basic sneak attack damage doubles the inflicted damage, but thieves get a bonus to this - for every three points in the subterfuge skill, the damage scales up (e.g. a subterfuge skill of 6 will mean that sneak attack damage is four times normal damage).
In the long run this may prove to be horribly unbalanced, but I hope it will make playing theives more attractive in the short term.
I've also got an idea to add an additonal weapon brand that does extra sneak attack damage.
And eventually, I want thieves to be able to open doors without making monsters aware of their presence.
Anyone got any other ideas for making thievery a valid playstyle?
