another legendary action character[edit source]
hey , just noticed that in act 2 the Shadowed Spirit of the Land is not listed. He has the legendary action Vengeful Playmate: Once per round, Oliver can spend a legendary action to summon The Wasting Quiet in an area after a summoned shadow is slain. The Wasting Quiet will affect any creature within the miasma of childlike terror with Silence and will take 3-24 necrotic damage every time they enter or start their turn inside the aura
As of patch 6: Shadow cursed shambling mound has the Legendary Action: Wretched Growth which makes creatures that end their turn within 5m of it take 3-30 necrotic damage and shadow cursed vines will sprout at its feet, possibly entangling it.
