The issue I notice is via vines I summon with fury leap. It seems like the vines don’t attack new enemies that enter their area. Usually if there is an enemy within range immediately upon their summoning, they will attack it, however new enemies that enter into the attack range of a vine that is not attacking will not be attacked.
Wanted to add that from what info I can find, the summoned vine has an attack range of 2 meters, engage range of 1.8, and pursuit range of 3. So perhaps enemies standing just outside of its attack range are causing it to “pursue” that monster which can’t be hit while there are other enemies that it could be attacking inside its range?
