Suspends the recovery time after casting, allowing chained spellcasting on a running initiative count: roll initiative plus casting time, then at the end of each spell roll 1d10 to assess and choose plus the next casting time, with every accumulated 30 marking a new round. Only spells of 4th level and below qualify, and no spell may be cast more than once while it runs - violating that ends the effect. Any non-casting action shifts to the next round and restarts the count the round after. When the duration ends there are 2 mandatory rounds of rest with no casting and no combat, though drinking potions and moving are fine. The components are a hummingbird's tongue and poppy seeds.
