Distraction (Ex): Any living creature vulnerable to the swarm's damage that begins its turn with a swarm in its square is nauseated for 1 round; a DC 13 Fortitude save negates the effect. Even with a successful save, spellcasting or concentrating on spells within the area of a swarm requires a Concentration check (DC 20 + spell level). Using skills requiring patience and concentration requires a Concentration check (DC 20). The save DC is Constitution-based.

The vineswarm gathers due to the will of the verminvine

A vineswarm attacks to defend the verminvine or to assist the verminvine in gaining the nutrients it requires. See the verminvine for more about the vineswarm.
