Increases your spell resistances by 100 for 1 min. Every time a hostile spell lands on you, this bonus is reduced by 10 resistance.

How it works

Its aura procs every time its trigger condition is met.

Mercurial Shield is built from 2 client effects, applied in this order:

  1. Effect 1 is Apply Aura (effect type 6). It applies aura type 42. It triggers Mercurial Shield.
  2. Effect 2 is Trigger Spell (effect type 64). It triggers Mercurial Shield.

What it does

Mercurial Shield is a spell with an instant cast, no range (it targets the caster) and effects that last 1 min. When cast it applies an aura. It also casts Mercurial Shield (record #26465) and Mercurial Shield (record #29286).

Generated from the SpellEffect, SpellMisc, SpellCooldowns and SpellRange records in the WoW Forever beta client, build 1.60.1.70532. Effects the client marks as internal hooks are left out.
