Arcane is a damage type in Shadow Era.

Arcane damage was once a more limited type in the game, with few cards either dealing it or interacting with it.
However, it received more support in Shattered Fates, including allies that can deal this type of damage with their attacks.
Arcane damage is now highly associated with Priests and the Templar alignment of allies.

It is shown on the card by a "yellow orb of energy" icon.
