I’ve been playing a bit more 13th Age lately. We just jump started the Living 13th Age game in Jackson, MI, so you should go if you can! How about a feat to help you get out of combat?
Adventurer Tier: Gain a +4 bonus to saves to disengage.
Champion Tier: Gain a +4 bonus to escape being grabbed. You may add the escalation die to all disengagement checks.
Epic Tier: You only need to roll a 9 to escape being grabbed or disengage. You may add the escalation die to all checks to escape being grabbed.
