A bit of a mis-placed sneak attack damage thing going on sorry. I meant that as an assassin you get for example 1d6 sneak and if you study target for 3 rounds it doubles to 2d6 etc so I have just finished the char and he has 7d6 sneak from both classes(3d6 rogue, 4d6 assassin), now using mongooses book is that 8d6 assassination damage or 14d6 total damage?
