Current abilities
FluxInfuses a lone enemy unit with swirling, volatile energy, dealing damage over time and slowing the target. The damage is not applied if another enemy unit is near the target.
Magnetic FieldArc Warden generates a circular distortion field of magnetic energy. The Magnetic Field grants bonus attack speed and protects allied units within it by evading attacks coming from outside the field. The Magnetic Field pulls runes, and runes inside Magnetic Field automatically activate.
Spark WraithSummons a Spark Wraith that slowly materializes and patrols a targeted area until an enemy comes within its range. Once a target has been found the wraith fuses with them, dealing magical damage and slowing the unit.
Runic Infusion innateRunes of Power fuse to the Self. Arc Warden gains +1.5 all attributes permanently whenever Arc Warden or the Tempest Double activates a Power Rune.
Tempest DoubleBriefly refocusing its fractured elements into a single form, the Arc Warden is able to create a perfect electrical duplication of itself. The duplicate can use all of Arc Warden's current items and spells, except most consumables and items that drop on death. The duplicate has separate item and ability cooldowns. The Tempest Double loses its sense of self and fractures over time, becoming slower and less accurate.
