Trying to make a basic attack replacer (new skill) to add some custom fx to basic attacks.

Problem:

1) Can't make this skill to attack twice with dual weapons.

The thing is i cant find skill_attack_*_cast animation for basic attacks (if there is one), have to use Attack1,Attack2 from animation set for applying proper cast animation, and, as a result - problem#1

2) Can't find Basic Attack skill info (the one that sometimes appear on a pannel). Would love to know SkillID param for it or see how it works.

3) Can't find any triggers for scripting to catch the fact of "performing a basic attack" or anything that I could work with. (Was thinking about AnimationOverride instead of new skill)

Would appreciate any help!
