Phase Spiders are line-of-sight creatures.
With that said, there's a bug that allows a Phase Spider to "phase" to any party member, regardless of where they are on the map.
Current Behavior -
Neera was at the top right corner of the Cloakwood map, leaving the clearing of the wood to the other 5 party members.
The party attacked a Phase Spider in the lower left region of the map.
The Phase Spider "phased" to Neera.
Expected Behavior -
Phase Spiders are line-of-sight creatures and should only phase to attack party members in view, not phasing to a party member on the other side of the map.
