Spellgrip
TactForge
Feat (level 4, Spellcasting or Pact Magic). +1 INT, WIS or CHA. Once per battle, a failed concentration save frays your spell instead of ending it: a frayed spell ends at the end of your next turn unless you spend a Bonus Action on that turn to steady it. Another failed concentration save ends it at once, and dropping to 0 hit points still ends it
