Multi-Hit Spell Level Scaler is a Foundry VTT module for the dnd5e system that allows certain spells to scale by adding extra hits to a single target, instead of increasing damage per hit.
The module uses a total hit pool model: 1 hit = 1 target = 1 action. Only the first hit of the initial cast consumes a spell slot; subsequent hits can be resolved later with a brief prompt.
Spells are configured directly from their spell card using the "Multi-Hit" button. You can choose the hit activity, set the base number of hits, and define the number of additional hits gained for each higher spell slot level.
Examples of use: Blazing Ray and Magic Missile.
Current limitations: Template-based activities are not supported in this controlled workflow.
