Sigil of Voltaris (Blue)

Sigil of Voltaris’ first ability triggers when it enters the arena (e.g. resolves on the stack or when it is put into the arena from another card’s effect). It also triggers when it leaves the arena (e.g. when it is destroyed, when it is banished, etc.). This is a targeted effect: you must target a hero when you add the triggered effect to the stack. You will deal 1 arcane damage to that targeted hero when the triggered effect resolves.

Sigil of Voltaris’ first ability is not functional while it is defending. It will not trigger this ability when it leaves the arena while it’s defending on the combat chain.

Sigil of Silphidae’s second ability triggers at the beginning of your action phase. You will destroy it when this triggered effect resolves.
