Alyosha is a Stellar-Conduct support who can heal the active character with Tugarin, who is summoned by his Burst. His Skill or the end of his Normal Attack string applies the Hunter's Mark. Consuming the mark with these abilities (or having Tugarin hit a marked target) grants the team Hunter's Precision, boosting the ATK of on-field characters. While in a Polestar Field, Alyosha also grants a 20% Stellar-Conduct DMG buff. His Burst can additionally taunt enemies.
Alyosha's [C1] gives him 15 Energy when a teammate triggers an Electro-related reaction, effectively changing his Burst cost from 70 to 55. This has a cooldown of 18 seconds.
At [C0], if Alyosha is the only Electro character in the team, his Energy Recharge needs may become unrealistically high. As such, Energy Recharge weapons are highly encouraged.
