Decisive Form is a common minor card out of the Synergy pool. Your Main ability deals 10% more damage, whatever weapon grants it.

A clean pick when your Main attack does most of your killing — it follows the slot even if you swap weapons. Skip it if your Special or Ultimate is the real star.

It stacks up to 4 · it only turns up when your Main ability can actually use it · it can be offered for 11 of the 34 abilities.
