Thermal Sunder is one of the best AoE nukes in the game. Titania is one of the most mobile frames in the game since she can cast abilities while flying around.

That's all there is to it, there's no specific synergy between the rest of her kit. It's just for moving fast and nuking.

Sunder gives a radial cold proc. If u hold it, it gives a heat proc. If u have a heat proc on the enemies already, (from a heat sunder), using a cold sunder will do blast damage equal to the total damage the hear would have done. This creates a massive blast. I think this is amazing on titania as u gotta build her for strength as well, and sunder has massive strength scaling

It's a speedfarming blitz build. Doesn't do so hot in Steel Path since the helminth version has it's damage capped, but in base starchart it 1-3 taps pretty much anything including those pesky Ancient Disruptors.

A build like this allows you to basically afk spam 2 towards extraction. It takes ~90 seconds to complete capture fissures if you're farming void traces/ cracking relics.

If you don't have Primed Sure Footed, you can use Preparation and simply use your 1 on yourself to prevent knockdowns and statuses but you'll need more duration (from something like Molt Efficiency) so it's comfier.

I recommend only using this kind of build while solo blitz farming since:

• 1: it's faster solo since you extract the instant you reach extraction, and you can skip the end of screen loot by pressing spacebar (for PC).

• 2: it's really boring for teammates to be paired with a Thermal Sunder Titania. It also doesn't really make the mission much faster since you're not speeding up your team (like with Volt or Wisp).

I mean, a volt doesn't really speed up my missions cause he ends up making me backflip halfway to Lua to control my momentum and most times I still show up within a couple seconds +/- of the volts lol

Another good alternative to Primed Sure Footed for Titania is the motus set. [Motus Signal] in her exilus slot, [Motus Setup] on a shotgun, and [Motus Impact] on a melee gives stagger immunity in the air and only takes up 4 mod capacity on Titania if signal is unranked

... the other comments have it mostly covered, but it's worth adding that Titania wants to have an ability to cast, preferably one that doesn't interrupt her movement and doesn't require targeting an enemy, while she's in her 4. This is to get and maintain stacks on her 4's augment (Razorwing Blitz), which is what elevates her from "reasonably fast" to "speed demon from hell".

If you don't subsume an ability on her, your best bet is her 1. (You'd want to invert "tap/hold" on her so you can just tap it to cast it on yourself with no enemy required.) And that's... fine. It's kind of low-impact as far as abilities go.

So people instead turn to subsumed abilities, and... hey, turns out that Thermal Sunder doesn't require an enemy to be targeted and doesn't interrupt movement, and is really really good.

So the end result is that by meeting the conditions necessary to achieve peak speed with Titania, you also get one of the best nuke abilities, just going off as you zoom through the level, in one neat package.

Its just a way to speedrun relic missions.

If you plan to use it in actual content i recomend archon vitality, this will also double the heat procs from your dex pixia

Thermal Sunder is an AoE damage and status proc ability from Gauss that you can Helminth subsume to other frames. Tap for Cold, hold for Heat, but you can reverse them in the options.

I like to use my Thermal Sunder Titania to quickly solo clear Fissures. Activate her 4, fly to a room, Thermal Sunder, fly to the next room, repeat until everything dies. Head to extraction. She can clear Mariana in just 50 seconds without even trying.

Thermal Sunder is the subsumable ability of Gauss in Helminth. To wit, Thermal Sunder Titania is primarily used for normal Star Chart fissure due to how easy it is to kill enemies while moving when you tap or hold Thermal Sunder. Put Archon Vitality on a build for the heat proc and you got a mobile nuke machine in your hands.

Is Nezha's trail bad on her? Maybe with Archon vitality, she zooms and burns...
