Spell Block

Spell Block is a defensive ability that protects the unit from most single target abilities, ranging from basic small abilities to the strongest single target ultimates.

Mechanics
Spell Block acts as a passive effect, activating automatically when a blockable single target spell is targeted at the unit. It may also come in form of a buff, protecting the unit while the buff is active. All Spell Blocks have a down time and go on cooldown after blocking a spell. It does not provide permanent protection against single target spells. Spell Block only blocks spells upon cast, it does not cancel already ongoing cast when going off cooldown while already affected by a single target spell.

With a very few exceptions, Spell Block does not protect against area of effect spells. It also does not protect against single target spells when hit as a secondary target. The unit must be the primary targeting order to block the spell. If a single target spell has an area effect, Spell Block also completely negates the area effect, effectively protecting nearby allies as well, but again, there are exceptions to this. Projectile-based spells are usually blocked upon impact, and not upon cast, with a few exceptions.

A spell's interaction against Spell Block may change if the ability gets changed by other abilities, talents or by. For example, when a single target turns into a non-targeted spell, Spell Block may no longer block it.

Spell Block does not block any active attack modifier and does not block any abilities of allies.
