Conjure Woodland Beings

Hi all,

I have been looking at the wording on ‘Conjure Woodland Beings’ (2024), and am trying to understand the following:

The spell states, “Whenever the Emanation enters the space of a creature you can see and whenever a creature you can see enters the Emanation or ends its turn there, you can force that creature to make a Wisdom saving throw.”

Does this mean if a Druid casts this, it has to move the emanation towards the target for the effect only? What if a creature moves into the emanation’s space? Does it trigger the effect? 

Would value your thoughts. 👍
