It seems Matador style in Demon hunter, its techniques does not scale with the weapon's accuracy.

Code:

* Initial Damage: 70 Darkness Magic, flags: no_reduc, magic, sk: Bellowing Stag (/obj/skill/bellowing_stag) , wep: null
* play_atk_anim was .
* 152 Evade VS 206 Hit.  (Damage Hit Mod was 0)
*2 Roll(s) Remaining. This one was a miss.
*1 Roll(s) Remaining. This one was a miss.
* Critical check: Defender was critical immune or crit_multi was 0. (70)
* spec_flat_reduc was 0. (70)
* amp_multi was 1.06. (74.2)
* elem_reduc was 1. (73.458)
* Damage evaded; evade_multi was 70. (73.458)

With your test of bellowing stag, that is entirely intentional. Bellowing Stag does not use SWA whatsoever, and I remember it being an example in the test patch notes of a skill that would use a set accuracy value instead.

All skills that do not have accuracy innately will use a default accuracy of 90 instead, making them not too far behind standard weaponry.

Marking it as Solved then.
