[T Corp. Class 3 Collection Staff] Don Quixote

T Corp Don, an extremely exceptional tank when it comes to her sheer versatility, utility, and tankiness. She has a very high HP pool, her passive allows her to heal 80% of her health back if left on 24-48 HP (Level 45), and she has pretty fast speeds. She also has extremely high clashes which gets even further boosted by her Borrowed Time state, which also boosts her speed as well. Borrowed Time also works extremely well with her passive, as when it expires, she's normally down to 1 speed due to the bind but also gains 8 aggro on a slot to still tank and use her guard to get Borrowed Time back. You have to spend one dead turn though to set it up, so it's recommended to use the guard when you have nothing but S1s or turn 1 to set up a nuke with her S3.

What makes her truly stand out as a tank is the debuff she inflicts onto the enemy with her S3, Time Moratorium, which stores the damage the enemy takes while it is active, and when it's effect expires the stored damage will hit the enemy all at once as Sloth damage, with an additional +30% (or +15% if you inflict it again the very next turn) more damage being added onto all of the damage stored. This effect is pretty much a better fragile in every way and fragile can even stack onto this stored damage.

The downsides here is the cost to inflict Time Moratorium being 10 Tremor, which isn't too much of an issue. Her guard gives her the Borrowed Time state, so if you don't want to consume Tremor on the target and also make full use of her high clashing skills, you have to use her guard which wastes a single turn when you could've been doing more damage. Her Borrowed Time state can also be pretty detrimental against opponents who can inflict bind, which is a niche risk, but she can instantly stagger when she gets hit with 4, 3, or 2 bind on turn 1, 2, or 3 respectively. Additionally Borrowed Time also gives you fragile but it gives less the longer you stay in the state. It wouldn't matter as she'd be a monster at clashes, but against enemies with unclashable attacks or an overwhelming number of attacks, she will be shredded apart.

Finally, her S3 also triggers Amplitude Conversion into Tremor - Chain, which does decreases 1 Clash Power for the enemy for every 10 Tremor Potency they have at a maximum of 3. While this is useful, there are also just better options for Tremor, such as Tremor Reverb, and it replaces the current Amplitude Conversion, forcing you to reapply that better version.
