Multiple shadow clones?

Hello! I am new to the rogue class and at the moment I have a level 81 rogue (ranged weapons build) in WT4. I was just doing routine fighting monsters in a helltide one day, and was suddenly joined by another rogue player during in an event. I think she/he was level 100 (can’t remember) but what I noticed was that this player was able to summon multiple shadow clones! This player was also using a ranged build and not dagger or melee based. As a rogue, how can I summon multiple shadow clones? My ultimate skill is only able to summon a single shadow clone. Is this ability granted by some item? I have grasp of shadow gloves but it doesn’t seem to help me summon multiple clones. I tried searching this topic on the internet and this forum but found nothing.

Was it barrage and or he was using Grasp of Shadows? Plus can have Shadow Clone up.

forget the entire shadow clone thing, they are bugged or dont work at all.
