Phase Blade

For 3 rounds, your melee weapon attacks become Melee Spell Attacks using INT. Each hit triggers Warped Edge effects normally. Additionally, on any turn where you land two or more melee hits on the same target, you may spend a Bonus Action to unleash a Phase Strike - the target is simultaneously hit across three temporal states, taking 1d10 Cold + 1d10 Fire + 1d10 Force damage. Phase Strike's three damage types cannot be individually resisted - the target must have resistance to all three to reduce any of them.
