How to Play Rei



Support Team with Damage Bonuses

Support Team with Damage Bonuses

The primary use of Rei's kit involves buffing Attack cards with more damage to clear waves and Bosses faster. Strike of Darkness enables 100% more Basic Attack card damage for a turn, while Dark Condensation will select an Attack card of your choosing to buff it with 100% more damage for a turn as well.

Predator's Blade allows Rei to grant the team the Morale buff, which provides 20% increased Attack for each stack. This can be useful for every DPS characters to further maximize their damage output if needed.

As a support damage buffer, make sure you focus on buffing your main DPS Attack cards so you can maximize the damage output of your team composition.

Exhaust Specific Cards

Snack Time is one of Rei's best cards as it triggers 3 effects for 0 AP cost. This allows her to Exhaust specific cards for better draw chances to target draw high-value cards, provide 100% Heals, and draw 1 card to further enable your actions within the turn.

Viable Void Sub-DPS Role

Since Rei has a few cards that can also deal good damage, she can also be viable as a sub-DPS for Void teams that want to capitalize on attribute weaknesses. Her Predator's Blade let's her deal 250% damage while also providing Morale, while Strike of Darkness also deals 100% damage and buffs your Basic Attack damage all for a measly 1 AP cost for each card.

With most of her cards being only 1 AP Cost, Resonating Darkness provides a 40% damage increase for any 1 AP cost cards which can prove effective for both Rei herself and any teammate that has the same AP cost cards.
