Entomophobia

FLAW FEAT

You are afraid of insects. You've learned to handle common insects near your space, such as flies or the occasional ant; but groups of insects terrify you, and the mere thought of being touched by a bug makes you break into panic sweats.

• At the start of your turn, when you are within 30ft of an insect swarm or insectoid creature (your size or larger), you must make a DC 15 wisdom saving throw, or become frightened of the swarm/creature for 1 minute. You may repeat this saving throw at the end of each of your turns.
  Succeeding on this throw makes you immune to further saving throws for that swarm/creature. Individual insects (tiny) do not count for the purposes of this check unless your size is tiny.
• Whenever you take damage from an insect swarm or insectoid creature, you must make a wisdom saving throw of DC equal to the damage dealt. On a failure you suffer disadvantage on your next attack roll or ability check made before the end of your next turn.
• Whenever a swarm enters your space, you must spend your next action attempting to leave the space by any means necessary. You cannot take bonus actions or reactions while swarmed.
