Feat
Form Cascade
Falls into another mastered body instead of reverting
When casting Polymorph, spend one additional spell slot of the same level to add Form Cascade to that casting.
Once during the casting, when the active form reaches 0 HP and would revert, the caster may consume one remaining transformation to enter another mastered form immediately. This change takes no action and occurs before the caster returns to their original body. Below Polymorph Level 8, the casting must have the Ephemeral Aegis.
| Polymorph level | New form's starting HP |
|---|---|
| 6 | 25% of maximum HP |
| 8 | 50% of maximum HP |
| 10 | 100% of maximum HP |
If no transformation remains, or Form Cascade has already triggered during this casting, Polymorph resolves normally.
