I found relic of the demon queen doesn't triggered by mech(Sky Circus) or turret(Thumper turret) action. I estimate companion (ex, ranger's pet and necromancer's minion) attack also doesn't count as player's action. We spent a skill slot for CC but can't benefit from that sigil/relic. It's pretty unfair, isn't it?
I hope ArenaNet fix these sigils/relics before March 19 balance patch.
