Question

When assigning indirect damage, if all legal targets have been assigned damage equal to their remaining hit points, and there is more damage, does all overflow disappear? As an example, if you have 1 HP remaining, and no allies, and Sandman attacks for 4, per the “you can only assign indirect damage as the target has HP, not counting other interactions” ruling, 1 Damage is assigned, and the other 3…. something…. If you then prevent 1 damage, as an ‘other interaction’ are you fine?
