Priestess

Standard Evolutions:
Priestess I, II, III"'Rarely seen outside their Temple in the remote peaks of Bandaku, these practitioners of the Photonic Arts can manipulate healing light.'"

Elite Evolution:
Divinity"'Saved by the monks of Bandaku's Photonic Temple, Divinity walks the realm, bringing light to its deepest corners and darkest souls.'"

Strategy:
Not only does Mark of Light provide a small amount of direct healing, but the effect also heals the targeted character whenever they deal damage. But pay attention: the Mark of Light status effect only works the turn it is applied. For maximum benefits, use on a low-health ally at the start of a round so they can heal when they attack. And if your Priestess is your last character standing, always use Mark of Light before using Lightwave for maximum healing. Lightwave is a powerful ability that can have a huge impact throughout battle, especially when used in synergy with Priestess' Concentrate trait. So try to avoid using abilities in early rounds of battle to charge up her Concentrate buff. The Concentrate buff does not affect the life-steal effect of Mark of Light, so in most circumstances use Lightwave to expend any Concentrate stacks.

Items:
Burst & Time Warp can be very effective on your Priestess. Mark of Light is most effective when used at the start of rounds, so if it Bursts, you’ll save AP. If you also get your Time Warp, then you can apply Mark of Light status effect to multiple allies. Getting Burst or Time Warp on the 4 AP Lightwave provides some serious damage & healing capabilities. Apply a Weaken item for nice synergy with her support abilities, or try an Amp item if you find yourself using Mark of Light often.

Team:
Try and create a team with a selection of low cost attacks so your Priestess can gain multiple Concentrate stacks before unleashing a powerful Lightwave, which can usually offset any damage her allies have taken in the first few rounds. For a more offensive team, try a Demon Wing, Swordsman, or Dark Archer. Or balance that team by swapping in a Shield Keeper or Giant.
