Boon Keyword and Support Cards

Boon is a new keyword first being introduced in Legends of Runeterra with the Worldwalker set on May 25, 2022. These are special effects that attach to another card in your deck, and activate when they are drawn.

Boons attach to another card in a deck. When that card is drawn, activate the effect.

They can be considered opposite to mechanics such as Poison Puffcaps or Caithlyn’s Flashbomb Traps in LoR – they are placed in your decks and you want to actively draw cards to maximize their effect. Use this keyword to buff the cards in your deck as you advance your game plan!
