Spell shield

Not to be confused with Magic shield

General

A Spell Shield refers to one of several effects that have the capacity to negate hostile abilities from applying to the recipient.

• The shielding can vary per case with other included mechanisms such as  on-hit effects and subsequent targeting ( Bouncing).
• Spell Shields negate effects coming from champion abilities,  monsters and items, with the exception of summoner spells and persistent damage from  AoE DoT and passive  DoT effects.
• Multiple active Spell Shields over a single unit will break simultaneously. This is intentional.
• Spell Shields take priority over  shields and conditional  crowd control immunity.
• Dragons' attacks can be blocked, but their  knockback upon taking damage cannot.
• Abilities applying multiple instances of damage ( Boomerang Blade, Unleashed Power, Blooming Burst) will only prevent a single instance of damage.
• Some abilities that have already applied onto the target ( Death Mark, Umbral Trespass, Sleepy Trouble Bubble) do not get blocked.
• Some empowered basic attacks will also trigger Spell Shields ( Power Fist) but the damage being blocked, being total or bonus, is case by case.

Single ability

The following will block one enemy ability, with precedence given to the ability spell shield. If the ability is of an enhanced basic attack (e.g. Harsh Lesson, Power Fist) the spell shield will not block the damage of it, but only any additional effect it might have, like  crowd control. In the case of Harsh Lesson, the spell shield breaks even if the attack doesn't have any crowd control effect with it.
