Alyosha Build and Guide

Alyosha is a 4-star Electro Polearm character who is most commonly played as a Stellar-Conduct support and sustain for the active character. While this limits his use due to the presence of powerful off-field damage dealers in the archetype, his buff volume - doubled at C6 - allows him to nonetheless serve as a great and simple option, setting up his buffs with Skill and activating them and providing Electro application with Burst.

Stellar-Conduct is a reaction that replaces Superconduct when certain characters are on the team. It deals no damage when triggered, instead spawning a Polestar Field around it. This applies the 40% Physical RES Shred from the base reaction while also activating Radiance: Stellar-Conduct effects in kit - many of which allow characters to deal direct Stellar-Conduct damage. It additionally provides a DMG Bonus for the Electro and Cryo DMG and a Base Reaction Coefficient for direct Stellar-Conduct damage based on a tally which counts whenever these elements are applied; this starts at 29% and 1.45 at one stack, and increase by 1% and 0.05 to a maximum of 40% and 2 respectively. These bonuses are granted every 4 seconds, with the tally beginning anew each time. Note that if both Stellar-Conduct and Stellar-Swirl are triggered by the team, Radiance: Stellar-Conduct will take priority.

Similar to damaging reactions, direct Stellar-Conduct damage scales with EM, reaction damage bonuses, ignores DEF, and does not benefit from standard DMG% - unlike typical reaction damage, it can also CRIT. Direct Stellar-Conduct damage is considered to be of the element of the unit dealing it and is based on the multiplier and the scaling stat listed in the ability instead of level, with Stellar-Conduct damage additionally being multiplied by the Base Reaction Coefficient.

As previously mentioned, Alyosha’s Skill and Burst are tied together to fully enable his kit. His Skill has a Tap and Hold version, with the latter allowing for manual aim; however, both of them achieve their core role of applying a “Hunter’s Mark” on the enemy. Hunter’s Mark has no effect on its own, but can be activated when reapplied to grant an 21.2% ATK buff to the active character for 15 seconds at talent level 10. When Alyosha has Radiance: Stellar-Conduct, he additionally grants 20% Stellar-Conduct DMG.

However, Alyosha is not reliant on waiting out his Skill’s 15 second cooldown merely to activate his buffs. His Burst summons his hound Tarquin, and creates a Fulgurite Hunting Field which can taunt enemies. Both deal Electro damage to enemies every 2 seconds; enemies that take damage also have their Hunter’s Mark activated, forgoing the need to reapply it in order to activate it. His first Ascension Passive additionally allows Tarquin to heal the active character when it attacks.
The rest of his base kit goes relatively unused.

His second Ascension Passive grants him DMG% based on his Energy Recharge, but his damage is negligible and so this is rarely relevant. His Normal Attacks are substandard, only used to trigger weapon Passives such as Favonius Lance.

Finally, as a 4* character, his Constellations are "relatively" accessible. His C1 till C4 are relatively unremarkable: C1 reduces his Energy requirements significantly and C2 extends his Burst duration by 6 seconds and allows Tugarin to apply Hunter’s Marks to improve his already good uptime; his C3 meanwhile improves his ATK% buff scaling to 25%, and C4 also allows him to heal off-field characters. His C6, however, is the real deal. It not only doubles his buff volume to a great 50% ATK and 40% Stellar-Conduct DMG, but also allows him to provide an additional 100 Elemental Mastery to the active character! This allows the sheer volume of his buff to compensate for his inability to buff off-field damage dealers.
