Upon pickup, add 1 Whistle to your Deck.

On pickup it adds one Whistle to your deck: a 3-cost Ancient Attack that deals 33 damage, applies Stun so the enemy does nothing on its next turn, and Exhausts. Upgraded it deals 44. Because it Exhausts you get one use per combat, and it comes back for the next fight.

When to take Tanx's Whistle

Take it from Tanx in Glory when your deck lacks one big hit for bosses and Elites, since 33 damage plus a skipped enemy turn is a strong swing. A thin combo deck feels the dilution.
