Combat Planner

Plan how the creature may behave as the fight develops. Add as many rounds as you need — the planner is open-ended.

Forge CR uses the first 3 rounds of this plan. Planning them is not a rule at the table — it is how Forge learns the creature's expected routine.

First 3 rounds — this is what Forge CR uses.

Longer encounters usually benefit from a meaningful change in tactics, objectives, monster state, or battlefield conditions.

Add Actions or other abilities first so the planner can reference them.

Design estimate

Assigned CR is your chosen game CR (used for XP and encounter budgets); Forge CR is a design check on the combat data entered.

Monster Forge is a design and encounter-planning aid. Analytical ratings and recommendations are tools for the GM, not guarantees of how a fight will play at the table.
