The 30% cut never applied: each hand was passed itself as the other hand, and the check compared the template to ItemType.WEAPON. The client (0x466EB0 / 0x46D200) multiplies min and max damage by 0.7 when both held slots contain an item_type WEAPON. Value change: players wielding two weapons now deal 70% damage per hand; single weapon, weapon + shield and unarmed are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
