Hello.
I did some search, but couldn't find an answer, so there it is.

1. If I fight a paladin-monk, and have hand to hand skill 75%, will be there a difference if I will have it 100%? Will I parry his extra attacks (redeeming fist, lightning strike) better?

2. What type of attack is a redeeming fist? Holy/positive, or physical?

3. What type of attack is a lightning strike? Holy/positive, physical or lightning?

Thanks!

1 Likely, but can't be sure, maybe parry isn't the thing there.
2 Think wrath-like?
3 None of the above.

I know not very helpful, but I'm learning this as I go.

Best advice EVER: when you have questions about a race/class/spec
make your next character one and 99% of your questions will be
answered. Make sure you have fun though.
