I'm trying to swap around the axe and sword perks (crit and bleed), add daggers to one handed sword perk and add a stagger chance to mace/hammer attacks.
I was successful up to a point; being able to get axes to crit and swords/daggers to bleed (I haven't started on the mace/hammer stagger yet).
Problem:
1. The perk only works when I put 2 points into the specialisation instead of one.
2. I don't see where or how to define the properties of rank 1 2 3 in the perk. (putting anything in the Num Ranks box causes the game to crash when you go to the skill menu, specific skill).
3. Bleed on swords/daggers was working (when I only had iron type material done), but now that I have added all the other types to be the same as the axe had (except with swords) it has stopped working. (even when it was working I still had the problem of needing to have 2 points in the perk).
Never modded anything before, any help or advice would be much appreciated.

Interesting thing I found:
The perk bleed functions are actually called
PerkBleedingSword(type)(number)
Making me think that this is what they had in mind originally, then changed it around before release
