Not to be confused with Boon (slang).

A boon is a designed-for-digital, MTG Arena-specific marker introduced in Alchemy Horizons: Baldur's Gate that represents a delayed trigger.

Description

A boon is a separate game object with a triggered ability created by cards, similar to an emblem. Boons are used for triggers that could be delayed over many turns, such as a player casting their next creature spell. The Arena software takes care of tracking this, so each boon acts as a reminder of what triggers are active. In contrast, typical triggered abilities either occur immediately or are delayed at most until the player's next turn, which requires less long-term memory by players.

There are two types of boons:

• One-time boons, originally just called "a boon" until Alchemy: Eldraine, disappear after the criteria for their trigger have been met.
• Multiple-time boons can be triggered more than once, with the boon disappearing only after the last of the predetermined number of uses.

Like emblems, there are no cards that interact with or modify an existing boon.

History

Before boons were introduced, a few digital cards used similar phrasing but did not attribute the text to a boon, such as Tenacious Pup or Molten Impact. These simply used triggered abilities delayed longer than usual.

Boons were first introduced on ten cards in Alchemy Horizons: Baldur's Gate, to replace some of the mechanics on reimagined cards.

As part of the Alchemy: Eldraine update, the boon mechanics were modified to allow a boon to be used multiple times instead of always disappearing after being triggered. While the patch notes for the update indicate all previous cards with the mechanic would be errata'd to be called a "one-time boon", only the cards in Alchemy: Eldraine featured the new wording. Underbridge Warlock from the set is the first card to check if a player has a boon.

The first use of the new multiple-time boon mechanic was introduced in Alchemy: Ixalan with Merfolk Tunnel-Guide. It allows for the next three Merfolk cast by a player to explore. The errata for previous cards is implemented, bring them in line with the new "one-time boon" wording.
