Is Twister Skill is a Projectile and Piercing Skill?
Like if I use it with Timewarp Skill and Exposed mythic it increase its damge.

I already tried this with 50% pierce Chance, but it does’nt increase the damage. Twister does’nt count as piercing damage…

Twister isn’t considered a Projectile so doesn’t get increased DMG with Timewarp Skill.

if you use Exposed Mythic on Chest with Zenith +50% Pierce Chance on Chest or Head (100% Pierce if you use 2), your Twister and any other Skills will do +50% DMG when the enemy is Pierced.
