Spiritblade

Spiritblade is a Mystic ability.

In-Game Description

(Passive/Active) When allies stand next to an interfused object, they gain +1 damage; Interfused blazes can be used to grant nearby allies fiery attacks.

Upgrade

 Allies directly adjacent to an interfused object get +10 Stunt Chance 
 Blazing Sword/Burning Arrow: Changed from turn-ending actions to single actions.

Specifics

• The ally must stand directly adjacent to the interfused object; diagonal does not count.
• The Spiritblade aura is only created around interfused objects, not Blazes (or any non-stationary target?)
• +1 bonus damage only benefits physical attacks

The mystic gains the following abilities when interfused with a Blaze.

Burning Arrow

When interfused with a blaze, grant a free ranged attack to a nearby ally. The attack has pierce equal to Hero's potency and creates a blaze at the target.

• Ally must be equipped with a ranged weapon, within 5.6 tiles of the blaze
• The attack happens immediately when the mystic takes the Burning Arrow action.
• The attack uses the ally's ranged accuracy, weapon range, damage and effects

Blazing Sword

 When interfused with a blaze, grant a free melee attack to a nearby ally. The attack deals bonus damage and creates a blaze.

• Ally must be equipped with a melee weapon, within 5.6 tiles of the blaze
• The attack happens immediately when the mystic takes the Blazing Sword action
• The attack uses the ally's melee accuracy, weapon range, damage and effects
• As of v1.0, the attack does not use the ally's Long Reach; this may be a bug

Both

These details apply to both Burning Arrow and Blazing Sword:

• A leashed Blaze is required; lamps, forges and campfires do not qualify
• The attack gains pierce equal to the mystic's Potency
• The blaze created on the target's tile causes additional damage at the beginning of the target's next turn.
• If the ally is hidden they are revealed.
• If the target is killed, it counts as a kill by the mystic and not the ally, so abilities such as Wolfcall and Thornfang do not trigger.

Uses

Burning Arrow and Blazing Shield are greatly improved when the party has a reliable means to start fires at will, such as Ignite or Raider.

Elementalist lets your leashed Blaze continue burning indefinitely without needing debris.

A spiritblade mystic doesn't need Spell Damage and doesn't need to compete with other mystics for interfusion targets, so can co-exist well in a party with more than one mystic.

Burning Arrow and Blazing Shield are an excellent insurance policy for reducing RNG variance. Let all your heroes take their 85-90% attacks, and use spiritblade for a do-over on whatever misses.
