"When you play a spell, the Spellboost effects of cards in your hand activate. Effects vary by card." |
Spellboost is a mechanic exclusive of the Runecraft class.
Spellboost effects are activated each time you play a spell while the card with Spellboost is in your hand. Spellboost effects are separated from the ones the card has in play to help distinguish between them.
Spellboost effects usually encompass buffs for the card in question that stack as more spells are played, such as reducing the card's cost, increasing the damage its effects deal, or increasing the number of followers it summons. Some cards have effects that only activate if they've been Spellboosted a certain number of times.
Details[]
- Followers played with their Accelerate effects activate the Spellboost since they are treated as spells when they are played.
