Your burst spells linger indefinitely within your time bubble.

Prerequisites: Arcana Lull, Slow Path, 5th-level temporal tinker.

Benefit: Will save DCs for your spells are further increased by 1 when you cast those spells on creatures within your time bubble. This stacks with the bonus from Arcana Lull.

Compression: You may spontaneously apply the effects of the Persistent Spell metamagic feat to any spell you cast without increasing the spell slot consumed. Doing so immediately ends your compression. You do not need to possess Quicken Spell to benefit from this tweak. You can only affect spells up to 2nd level with this ability. At 7th level, and again at 10th level, this maximum is increased by 1, to a maximum of 4th-level spells at 10th level.
