Review

From Tanking, to healing, to damage dealing - Tiamat does it all. She is a tank that transforms into a damage dealer (while retaining her tankiness) after taking damage, or healing enough of her HP through her passive, [Mother of Evolution]. With it, she enters her ultimate form and gains an extra turn, allowing her to immediately use her skill 1, which does massive AOE damage. Besides her Ultimate Form, she still has AOE Healing over time, AOE Shields, and an AOE taunt, allowing her to be an oppressive unit in PVP while also being very good in PVE content, such as DokiDoki.

She's a great example of an early/mid game starter character that makes progressing through the PVE content easy, but while she still can be used in the highest difficulty stages, other characters overcome her later - especially in the 'speed' category, so how fast they clear a stage. Still, even outside of that, she's a menace in PVP and is very annoying to deal with.

Tiamat works extremely well with a unit like Lingluo and Sania in order to heal and get more stacks to get her closer to her Ultimate form. If you allow your opponent to pair her with those units in PVP, you won’t have a good time. Lily, too, is an amazing unit with Tiamat because of her built-in assist that procs on the S1, which can allow Tiamat to do twice as many of her AOE S1s in her [Mother of Evolution] state.

Pros & Cons

Pros

High AOE damage potential.
Hard to kill & can taunt.
Good team-wide sustain.

Cons

Low single-target damage output.
On auto, she will use her S3 first to Taunt enemies, while in PVE content (and even in PVP), you want her to start with S2 in a lot of cases - as her Shields are based on current HP.

Best Builds (Generic)

Before the owner takes action, if the owner has any debuffs, dispels 3 debuff(s) and increases their Effect RES by 25% for every 1 debuff(s) dispelled, lasting for 2 turn(s).

A PVP-focused shell option offering a triple cleanse and up to 75% Effect RES for 2 turns at turn start with a 4-turn cooldown. A solid option for characters who need to ensure they aren’t taken out of the fight by stuns, freezes, or other debilitating effects on their opening turn.

It can help her dispell some annoying debuffs that may make the run dangerous or slower to clear like SPD down\Def Down\Stuns

Triggers when the main body takes DMG greater than 25% of Max HP within a turn, healing the main body for 25% Max HP and increasing Turn Meter progress by 35%.

A strong personal sustain option for characters, granting them a 25% max HP restore and 35% gauge boost upon taking hits within a single turn greater than 25% of their max HP (on a 2-turn cooldown). Has situational use in PVE but shines the most in PVP, granting your teams extra healing and gauge boost on a semi-frequent cooldown.

A great option to increase the surviability of this character in PvE. Works great on Tia to help her transform faster.

When the owner Animus is about to die, halves their current Turn Meter, removes all effects on them, recovers 60% of their Max HP, and puts them into a 1-turn [Iced] state.,

The cooldown of the skill can't be reduced.

Allows the wearer to cheat death once every 6 turns. Upon dying, they will instead recover 60% HP and enter a special state, becoming immune to turn meter reductions, debuffs, buffs, and also gaining 200% increased DEF until the start of their next turn. A powerful option for keeping vulnerable high-value units alive in PVP.

Safest option that lets you recover if Tiamat gets bursted.

Amber is still the most generic good Tiamat build, but Gator is growing in popularity; it needs more testing to see which is best overall.

When a unit dies in battle, Purifies all Debuffs from the host Animus, restores 50% Max HP, and increases Turn Meter by 30%. Only triggers once if multiple units die simultaneously.

A PVP-focused shell option tailor-made for high HP Animuses who are weak to CCs. The moment an ally dies, the host Animus gets supercharged with Purifies, max HP Heal and a big Turn Meter boost. Ideal for heavy-hitters who don't die easily.

Gator has been a breakout star of this format and it's quickly showing its strength on any HP Scaler. Highly recommend trying out Gator Tiamat if you can get good stats on it. While it is less useful in the single Tiamat carry teams, those are not really a thing anymore. Gator makes her way less reliant on the rest of her team and can act more like a solo protective Tank with good damage rather than a heal spammed carry.
