IV Checker (All Heroes / All Rarities)

+Spd and -HP

Thrasir's best IVs are +Spd and -HP. Her B skill has a similar effect to that of Desperation built into it, so the easier it is for her to trigger follow-up attacks, the better. This stat is also a superboon for her, so an asset will allow her to get Spd+4.

Thrasir is a ranged magic attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Res stat.

Thrasir is a Mythic Hero, and when summoned, you will receive an Anima Blessing. During Anima Season, allies who have been given an Anima Blessing and appear together with Thrasir in batlle will receive a HP+5 and Def+5 bonus to their stats, increasing the party's overall power.

Thrasir Strengths

Exclusive weapon that is effective on dragons

Thrasir's exclusive weapon Ífingr is effective on dragongs, and will give her a +4 buff to all stats in combat if she is within 3 spaces of an ally. On top of this, it will negate that foe's guaranteed follow-up attack. While this is a very good weapon skill, it will also inflict a penalty on the nearest ally after combat, so you must keep an eye on where you are positioning your units.

Exclusive skill with built in Desperation

Thrasir's B skill Killing Intent will inflict Spd/Res-5 on a foe in combat and allow Thrasir to get a follow-up attack before the foe's counterattack, if that foe has taken damage or has an active penalty cast on them.

If an ally has a Seal skill, or an ally like Duma can cast damage on all foes on the first turn, this skill will be very easy to trigger, so edit your team with an ally who can help trigger it.

Flashing Blade makes special easy to trigger

Flashing Blade 4 will give Thrasir special cooldown charge +1 and +5 damage on her special when her Spd exceeds that of the foe. This has excellent synergy with Killing Intent, and effectively makes it so that Moonbow will be ready to trigger after the first attack, and on her follow-up attack, her special will deal additional damage, easily wiping out a large number of foes.

Thrasir Weaknesses

Inflicts a debuff on nearby allies after combat

Thrasir's exclusive weapon Ífingr gives her a powerful buff during combat with a nearby ally, but after this effect triggers, it will cast a significant penalty on that ally. This penalty can be eliminated through Harsh Command or Restore, so pairing her together with an ally that has one of these skills is a good move.
