Pick a weapon and the actions you have. Every legal three-action Pathfinder 2e turn is worked out exactly at every AC, so you can see which one deals the most damage, and where the best choice changes.
Write the weapon's dice first (2d8+1d6+6): Vicious Swing adds dice of that size, and a fatal die replaces them on a crit. Weakness and resistance apply to every hit, after a crit is doubled; all the damage is taken to be the weapon's type.
Each band is the turn with the highest average damage against that AC. Below it: how much that turn wins by over the next-best turn, in average damage. A short bar means the choice barely matters.
Dashed: Strike, Strike, Strike, the baseline that needs no feat or spell. Coloured: turns that are the best somewhere. Grey: the rest. Hover for any turn's numbers.
The turn you remember: every attack misses, or resistance soaks every hit. Same colours as above; a turn that wins on average can still come up empty more often.
