Spell is a type of card that a player can own, or a non-keyword effect that units can trigger.
Type of spells
There are 3 different kinds of Spell cards.
Some units can trigger spells or create spell cards. Some spells are unique to specific units. Here are some unit-generated spells:
- Mystic Shot: Ezreal can create them with his ability.
- Balesight: An effect unique to the unit She Who Wanders.
- Glacial Storm: Anivia can trigger two different versions of Glacial Storm, based on her level.
If a player plays a Champion, all duplicates of that card will turn into a special spell card. This card is a variant of a normal spell card that will also shuffle a card of the champion into the deck, in addition to its usual effect.
To play a spell card, a player must pay the Mana cost. If the player has any spell mana left, the spell will use up spell mana before tapping into normal mana.
Burst spell's effects trigger immediately, without progressing the spell stack. Also, the player continues their turn after the spell cast. This means, player can cast as many Burst Spells as possible, as long as the timer did not run out and player can pay the cost. If the player passes their turn after playing a burst spell, the opponent will get a chance to respond in the spell stack.
When a player doesn't play a spell and passes during a spell stack, the stack stops and resolves. Then the spell reaction starts rolling out, in the order of the last spell played occur first. If the outcome is predictable, a player can use the Oracle's Eye to view how the current spell stack will resolve.
