The question is, how much is it worth to increase Melee Damage by 5 for 300 seconds?
If that increase can help significantly to win a PvP fight or help kill a tough monster with a Sampire or some other melee fighter well, then I think that 1,000 gp for a bull fish steak (i.e. 1,000,ooo gp/1,000 steaks = 1,000 gp) is way but way too low, IMHO....
