ICE, ICE, BABY. There are those who are blessed by the gods, gifted with the ability to wield the elements. This gift is called a Vision, and Kaeya's specifically is that of Cryo. As such, he can harness the element of ice — both offensively and defensively. In Genshin Impact, he can cast a burst of ice that will freeze his opponents and he can summon icicles that cause damage to those who come into contact with them. If his health dips low, his Vision grants him a shield. He is also shown to be able to create objects from ice, such as a sword or other projectiles that he can use to fight.

CAVALRY CAPTAIN. Kaeya is a clever individual, possessing a strategic and perceptive mind. The Knights of Favonius often rely on him for any tactical plans regarding their missions even if his methods can be unconventional. He is also very proficient with the sword and other weapons befitting of a knight. He fights with grace and elegance, but also with a bit of flair for the dramatics. Unfortunately, he's someone who likes to show off so I'm sorry he's like this. :(

Abilities of OTHER characters mine would reveal: He's not a rat... yet.
I want to participate in Training Logs/Activities: Yes, but I'd probably like to balance handwaved threads and writing threads out. i'll get burnt out if i gotta write so many fight threads, i'm gomen, Kaeya would also probs volunteer to help train if they need extra hands! Otherwise, he's happy to defer to whatever grandpa needs him to do.
Training Activities Suggestions: Hunt Eustace. :)
When should the first Training Log occur? Probably next month so it's a nice offset activity during app/TDM months? 🤔 Not entirely sure how the cadence of the game works just yet though,,,
