You would need vampiric and cruel on a viscous anything just to keep yourself from suffering too much. I have never seen anyone choose to put viscous on anything, personally. I have both received and handed out viscous weapons as loot, though.
Heh. I am currently running a 14 Synthesist/11 Preacher that has it on his offhand and natural attacks. Let's just say he is ... very odd.
It's not our fault that the people in charge of producing this game and everything that goes into it have absolutely no standard or code on the wording of their own content. The feats are written by a million monkeys in a room with a million typewriters, plain and simple. There isn't a semblance of consistency anywhere to be found.
That being said, I think they screwed the pooch on Courageous, they didn't clarify anything other than that they made an entirely useless weapon enchantment AND really suck at writing what they actually mean the first time.
I agree. The enchantment would actually be competitive if it included all other morale bonuses. Fear alone isn’t worth it, at all. There’s simply too many other enchantments that are better.
