The Sectarian is a common card of the Darkness element, which for its rarity is very powerful. It has 3 and 4 attack and defense points respectively for a cost of 4 crystals. But there is a price to pay for this card... Its "Thirst 1" ability causes it to inflict 1 point of damage to a card that is on an adjacent square randomly before attacking. If there are no cards that can take the damage, it will remain inactive.
