Your spells function precisely and over a longer period of time within your time bubble, making them harder to resist.

Prerequisites: Slow Path, 3rd-level temporal tinker.

Benefit: Will save DCs for your spells are increased by 1 when you cast those spells on creatures within your time bubble.

Compression: You may spontaneously apply the effects of the Extend Spell or Linger Spell metamagic feats to any spell you cast without increasing the casting time or spell slot consumed. Doing so immediately ends your compression. You do not need to possess either metamagic feat to benefit from this tweak. You can only affect spells up to 2nd level with this ability. For every two class levels you posses above 3rd, this maximum is increased by 1, to a maximum of 6th-level spells at 10th level.
