Monster Effects

[TON3R]

If a monster says it is +2 against elves, and you and your helper are both elves, does the monster get +2 for each of you?

I originally thought so, but reading through the Munchkin Fu rules, under asking for help, it says that Hong Kong Cong is a +4 if a Samurai helps you, unless you are also a Samurai and his strength had already been increased.

Thanks!
