What WvW build was this?
“live long and prosper” – Obi-wan Kenobi
umm… phantasm build?
anyway it’s hard to tell as phantasms are part of weapon skills and with any combination of weapons you will have two phantasms at your disposal.
Most likely the greatsword’s Berserker, possibly the focus’ Warden. Both can spawn regardless of LoS.
Don’t ignore them, they can do a lot of damage and usually apply bleeds.
Actually Warden cannot spawn without LoS. Berserker is the only one that does not require LoS to my knowledge.
