"When it comes to threat level 5 the flora become more active in their aggression. The poison can affect you even if you don't breath it in, trees can usually move and attack with their roots and branches and some can spurt out acid that can burn through metal, leather and even rock. By this point flora starts to resemble fauna." Threat level 5 required one to be prepared for battle, gear and support magic wasn't enough to protect you.
