A phantom fungus prefers to ambush lone creatures. When it encounters a larger group, a phantom fungus often stalks prey for hours, waiting for the targets to spread out or make camp so that it may attack a single foe at its leisure. Though phantom fungi are not normally pack hunters, there are reports of groves working together to bring down larger foes. When faced with no other option than to attack multiple foes, a group of phantom fungi focuses its attacks on single targets. They prefer to attack noisier foes if possible-characters wearing heavy armor or those that make heavy use of loud attacks (such as bards or spellcasters) are preferred over quieter creatures.
