The additional on-critical sound damage from Electric Axe is causing retaliate effects to activate (such as Riposte, Fang-Faced Shield, etc), despite being an on-hit effect.
How to test:
- Use this against an enemy with 100% Riposte chance.
- The enemy will riposte the basic hit, and also the on-hit sound damage, which is not intentional.
This can cause infinite riposte loops if two Electric Guitars are being used against each other, by the way.
