Mysterious Book

About:
The Mysterious book is a niche use codex dropped by The Dark Lord.

As this book is an item rather than an ability, it may be cast at any time, not just when the player has no GCD (global cool-down). Adrenaline requirement: 0%

Cool-down: 60 Seconds

Duration: 60 Seconds (consumed)

Effects:
The Mysterious Book offers a unique ability: for the next 60 seconds, the next attack/ability/spell that a player casts, is guaranteed to have 100% hit-chance. Once a hit is performed, you will lose this ability. The hit will also have 100% critical strike chance.

Usage:
This effect can be used in a pinch to save yourself with a sometimes risky debilitate on bosses such as Araxxi, where missing it could result in death. This is also useful because it allows the use of spells such as vulnerability or ice barrage whilst wearing full melee armour or ranged armour, and not needing to worry about the accuracy penalty. A potential use is guaranteeing that a high damage ability, such as bombardment or snipe lands, whilst under the effects of deaths's swiftness.
