>!Regular 4-hit combo, but the last hit applies Hunting Mark!<
>>!ELEMENTAL SKILL :!<
>!Tapping deals Electro DMG and applies Hunting Mark!<
>!Holding enters aiming mode and locks onto enemies and applies Hunting Mark!<
>!Applying Hunting Mark to an enemy that already has Hunting Mark procs the mark and increases team attack by 14% (at level 1)!<
>>!ELEMENTAL BURST :!<
>!Summons a pet (Tugarin) and creates a zone that taunts enemies and deals electro DMG!<
>!Tugarin chomps enemies that have Hunting Mark applied on them every 2 seconds (the A1 passive makes it heal) and procsc it!<
>>!A1 PASSIVE :!<
>!Tugarin heals allies when he chomps enemies!<
>>!A4 PASSIVE :!<
>!SKILL and BURST deal more damage based on Alyosha's ER!<
>>!UTILITY PASSIVE :!<
>!When inside a Stellarconduct field, Hunting Mark also increases the team Stellarconduct damage by 25%!<
>>!CONSTELLATIONS :!<
>!C1 restores 15 energy to Alyosha when your team deals an electro reaction!<
>!C2 increases burst duration from 14s to 20s and allows Tugarin to apply an additional Hunting Mark before attacking (but it DOESN'T proc it)!<
>!C4 adds a heal to the lowest HP character based on Alyosha's attack!<
>!C6 makes it so Hunting Mark can stack twice; with 2 stacks, team members gain 100 EM!<
