Spawn in angry wolves (2-5) near the player so that they are close enough to lock onto the player, but not close enough to instantly damage the player.
If the wolves are too weak, give the player some Nausea for ~5 seconds at a time, and loop it so the player has his/her effects removed for 5 seconds as well, therefore creating a pattern:
Nausea, no effects, nausea, no effects, etc.
This lessens the chance of this being called OP, and actually gives the player a chance to kill off the wolves and find a safe shelter until the segment disaster clears.
