LeilaniBuild and Guide

Leilani has a unique mechanic that gives Moxie to allies when she enters battle (Passive from Insight 1) and every time she uses her Ultimate. For this reason, it is recommended to get her at least to i1 L1 as soon as possible.

When it comes to gameplay, one of her skills, “A Greeting!” deals bonus damage when the enemy is under a Control or Negative status, giving her a good synergy with debuffers. Her second skill, “Check Carefully”, deals more damage if the enemy is below 50% HP, so that should most of the time be selected as the last attack of the round or to finish off a low-HP enemy.

Since you get the resources back for raising her to insight 1, it may still be worth leveling her to fill a need for Beast DMG early on, or for her Moxie mechanic. Another way to use Leilani, since her damage is average at best, is to spam her cards early, so she can use her ultimate right away and give the team a head start. That's usually the way to go on sacrificial strategies, with Leilani leaving the battle early with her job done and giving room for the character in the Substitute slot.

You can also go the other way around and get her to max level, which is very cheap as well since she’s a low rarity unit, and setting her as a Substitute. That way, if someone in the team dies, Leilani enters and automatically gives 1 Moxie to all allies and 2 to herself, facilitating a comeback. Since her skill “Check Carefully” benefits from low health enemies, this tactic can be surprisingly effective.
