This is my first guide on mobafire. I hope this guide helps you to play better as swain.

I'm not too experienced on swain but have done lots of research and i know how his abilities work.

for help with the matchups :)

Passive: Swain can periodically target a nearby Stun icon immobilized enemy champion to rip out a Soul Fragment from them, dealing 20 − 105 (based on level) (+ 30% AP) Ability power magic damage and Airborne icon pulling them X-units towards him.

Enemy champion Damage rating takedowns will also leave a Soul Fragment behind.

Innate - Flock: Swain's ravens harvest Soul Fragments for him, Heal power restoring 4% / 5.5% / 7% maximum health. Swain can store up to 5 Soul Fragments in reserve, which empower Demonflare Demonflare.

Q: Swain unleashes five bolts of eldritch power in the target direction, dealing magic damage to the first enemies they hit. Enemies can intercept multiple bolts, taking bonus damage.

Bolts that kill their targets continue onward and restore 3% maximum mana. This can repeat indefinitely until the bolts reach their maximum distance.

W: Swain summons a demonic eye at the target area, Sight icon revealing it for 2 seconds, which explodes after 1.5 seconds, dealing magic damage to all enemies hit, halved against minions, and Slow icon slowing them for 2.5 seconds.

Enemy champions are Sight icon revealed for an additional duration and have a Soul Fragment ripped from them.

E: Swain launches a demonic wave in the target direction, dealing magic damage to enemies it passes through.

Upon reaching its maximum distance, the wave returns to Swain, detonating at the first enemy hit, dealing magic damage to all nearby enemies and Root icon rooting them for 1.5 seconds.

R: Swain frees the demon within for 12 seconds, gaining bonus health.

While Demonic Ascension is active, Swain drains the 3 closest Sight icon visible enemies to him, prioritizing champions, dealing magic damage to them each second, and Heal power healing himself for each enemy hit, reduced by 80% against minions and monsters.

After Heal power restoring 125 / 300 / 450 health with Demonic Ascension, Swain can end its effects early to cast Demonflare Demonflare, and automatically does so at the end of its duration.

If Swain dies while Demonic Ascension is active, he loses all of his stored Soul Fragments. If Swain dies during the channel time of Demonic Ascension, the cooldown and all Soul Fragments are fully refunded.
