Solo tamed it with an imprinted mana with 3k stam.

Waited under it until it was going to fire lightning at me, jumped up 3 times, with slight delays between jumps so on the 3rd jump (jumped the 3rd time when the lightning was around 1 second) to shock its right wing corruption. I kept repeating it and it kept shocking itself, then I moved to the left wing, then the back.

It took a bit of precision and learning, but I eventually figured out the timing and had it tamed in like 15 minutes. Alpha tamed as it’s lightning doesn’t damage it.

I took 0 damage with this method, and always dodged its lightnings and flock. Maybe this doesn’t work on ascended, but on evolved, I think this might actually be the best way to tame the desert titan if you have the skill to do it.

Overall, I spent about 2 hours trying to do it with other methods, like a tek tapejara, damaging with the ice breath, using a tek suit.. this one was way easier. And easier than finding quetzals on extinction.
