Often, the entry will limit the kinds of targets you can select. For example, living creatures, objects, or willing creatures. A creature is anything that has both a Wisdom and a Charisma score. A living creature also has a Constitution score.
An object is anything that lacks a Wisdom and a Charisma score, even if it is actually alive. (A rose bush, for example, is alive, but it's an object insofar as the D&D rules are concerned.)
根据Rules Of the Game的解释,Creature是指任何有WIS和CHA属性的东西,大树显然没有CHA,不能被算做Creature,解释中给的也是一种植物(玫瑰丛)
