Speculation about Mitya's element and role
By now, all of us should be aware that Mitya is a catalyst user. Looking into the Snezhnayan craftable weapons (most of which are explicitly tied to Stellar reactions), almost all of them increase ATK and EM, with the sword and catalyst even giving Stellar DMG%. The only exceptions are the bow which gives DEF and EM, and the polearm (still debatable tho) which provides ER and ATK. Unlike Lunar characters, it seems like majority, if not all of the Stellar roster is ATK scaling, as these weapons appears to be good options for them (sword for Odette, polearm for Alyosha, claymore for Sandrone). Currently, only Mitya is said to be a catalyst user, so it is safe to assume that the catalyst will be good for him. If so, then he:
should be ATK scaling
should be from an element involved in Stellar reactions (for now Cryo, Electro, Anemo)
does considerable Stellar damage (so Main/Sub DPS)
is a 5 star! (as Stellar Main/Sub DPS should all be 5 stars, as seen with Lunar)
Most of the past craftables have been compatible for their regions' characters, at least from Natlan onwards. Nod-Krai even had 2 weapons dedicated to 2 separate Lunar reactions (polearm for Lunar Charged, catalyst for Lunar Bloom). The only weird one was the Nod-Krai sword (ER and HP). I'm using this to fuel my hope that Mitya gets the 5 star role he deserves.... or he can just pull a Zibai and use previously available weapons.
Anyways, what are your thoughts on his vision, rarity, etc? Feel free to share and speculate.
