AbilityCaster

Remarks

Timing and eligibility, and nothing about damage. What an ability does when it completes is CombatResolver's, because that needs the targets it hit and this only knows the one it was aimed at. The split is what lets a cone ability go through the same caster as a single-target one.

⚠ Costs are paid when the cast completes, not when it starts. Paying up front means an interrupted cast has spent the resource, which every game refunds by hand and gets wrong for channels. A channel pays per tick, which is the only reading of "it costs mana per second" that survives being interrupted halfway.
