Tri-Boomerang

Tri-Boomerang

Ancient
Choose 3 Attacks in your Deck. Enchant them with Instinct.

On pickup you choose 3 Attacks in your deck, and each is enchanted with Instinct, which doubles that card's attack damage for the rest of the run. The enchantment is on the card, so upgrades and other bonuses still apply, and the cards count as enchanted for anything that cares about that.

When to take Tri-Boomerang

Take it from Tanx in Glory when your deck has three Attacks worth doubling, since a single big hit gains the most in absolute terms. It does nothing for Poison, Doom or Orb damage.
