Heavy Strike is a rare major card out of the Synergy pool. Your Main deals +60% damage and gains Force, but casts 0.15s slower.

Suits builds that want one big, shoving hit — great alongside Crumble or Force stagger pressure. The slower cast hurts fast on-hit status stacking, so pass if you rely on hit volume.

You can take it once · it only turns up when your Main ability can actually use it · it can be offered for 11 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Split Form, Lance Form, Scatter Form, Fanned Volley, Twin Barrage, Rippling Form and Lance Covenant. Take one and the rest are gone for the run.
