Gremlin Horn

Gremlin Horn

Uncommon
Whenever an enemy dies, gain and draw 1 card.

Whenever any creature on the enemy side dies, you gain 1 energy and draw 1 card. It checks only the side, so minions and summoned adds count as much as the main enemy. Uncommon shared relic, 225 Gold.

When to take Gremlin Horn

Best in acts full of group fights and in decks that kill in pieces, since each death mid-turn refunds a card and its energy. Fine at any point of the run, weak only against lone bosses.
