Instinctive Bond of Nature

Once per long rest, when you reach 5 hp or less in combat, you emit a powerful psychic compulsion for nearby nature to aid you.

All hostile creatures with the Beast or Plant type, as well as some Elemental/Fey/Monstrosity (GM's discretion), must make a CHA save with DC 8 + your level, or be charmed by you for 5 rounds.

In addition, if you are in a wilderness environment, roll a random encounter using a generator (e.g. Goblinist). Use yourself as the seed (e.g. 1 lvl 7 player) and Easy as the difficulty. Keep generating until you get a Beast or Plant or Elemental/Fey/Monstrosity (GM's discretion) encounter appropriate for the terrain. Those creatures join the combat on your side (not necessarily controlled by you).
