Soul Hunter/Death Reaper skill values

Well, maybe this post is redundant since it's just additional info about the skill on different levels, and there was already similar posts before, but from how I see those posts are kinda too old so I don't want to necropost, and I want to share what I found about the skill.

So basically here's my result after a few tests with Soul Hunter with my bow char, assuming bow/bowgun has a -5 mult penalty on first hit regardless of skill lv:

Skill const: 100 + 30[skill lv], const of both hits
Skill multiplier:
- 1st hit: 7.5 + 0.25[skill lv]
- 2nd hit: 5, regardless of skill lv
- 2nd hit bonus multiplier per Soul Hunt stack: 1, regardless of skill lv
MP recovery per stack: 5*[skill lv]
No idea about [Fear] chance.

Tested on Cabrigo mob in Ruins of Urban Elban map, with 100% stability, 100cr, no element, no buff. Cdmg, srd/lrd, and any dmg multiplier from passives and stuff are listed in the picture.
