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
• Blazing Sword does trigger Broadswipes.

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.
• As of v1.0, Burning Arrow does not take advantage of bonus damage from Vigorflow or Bloodrage.

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.
