Wrath

Wrath is one of the seven deadly sins and a mini-boss that can be found randomly on any floor. He typically attacks by launching active bombs towards Isaac or planting them in place as he walks around. In Revelation floors, however, this attack is altered around the corresponding chapter's mechanics.

Glacier Wrath
In the Glacier, Wrath appears to be a living chunk of fiery coal and his mini-boss room is often undergoing a blizzard as part of his main mechanic.

Behaviour

 * Wonders around the room randomly in straight lines.
 * Launches a Hot Bomb at Isaac, or plants one down, which deals contact damage.
 * When the bomb detonates it creates a temporary damaging fire which creates an area of warmth around itself as it burns.
 * Since Wrath is often fought in blizzard rooms with heat sources either incredibly sparse or non-existent, Wrath's own attacks are often the best/only way to be able to continue attacking him on order to beat him.

Upon death, Wrath leaves behind a Grill O' Wisp.

Tomb Wrath
In the Tomb, Wrath appears in Egyptian attire and is centred around the revival mechanic.

Behaviour

 * Wonders around the room randomly in straight lines.
 * Launches a purple Bomb at Isaac, or plants one down, which will home in towards any nearby Revival Rags and revive the monster upon detonation.

Trivia

 * The music that plays during Wrath's battle in Revelation floors is named Overclocked.
