Addendum

Keywords · beginner

Addendum is an ability word. An addendum spell gets a bonus if you cast it during your main phase.

How it works

• Addendum spells are instants, so they can be cast at any time.
• If you cast one during your own main phase, the addendum effect is added on top of the normal effect.

Rules notes

• Cast outside your main phase (on an opponent's turn, or during combat), the spell still works, just without the addendum bonus.
• Addendum rewards using your instants proactively on your own turn.
