Hi this is my first guide to my fave champ SWAIN.Swain is excellent solo mid champ and it has great harrasment.Swain is a tanky/ap caster who deals a lot of damage and has great CC
One the beginning it was hard to play but now it's fun and easy

Let's start with runes.

Marks: Greater Mark of Magic Penetration-this is normal mark for ap casters,i so recommend this.
Seals: Greater Seal of Scaling Mana Regeneration-swain needs a lot of mana so this runes+passive=You will always have mana
Glyphs: Greater Glyph of Scaling Magic Resist-MAGIC RESIST?! WUT?!-yeah you see,swain needs magic resist runes so he can deal a lot of damage with all spells
Quintessence:2 Greater Quintessence of Health and 1 Greater Quintessence of Magic Penetration-Like most ap casters at level 1 he has about 450HP so this rune is important.Why not 3 Greater Quintessence of Health???? well u need also magic pen and 2 is just enough.

When is stared to play with swain i thought"ABILITY POWER,ABILITY POWER,ABILITY POWER"-NO
See when u cast Q what happents?-Bird slows over 3 seconds enemy and deals damage-When you cast a bird it dosent hits enemy like Veigar's Primordial Burst and deals damage instantly,it deals DAMAGE OVER TIME(DOT)
When u cast W what happents?-When you cast it after 0.5 seconds circle stuns enemy champs. in it-Look it's a ****ing stun it dosent do any ****ing damage it STUNS enemy.
When u cast E what happents?-Swain throws a bird **** and it deals DOT like ignite-Same **** as Q i dont want to ****ing repeat it.

BEST-This is great for escaping and chasing enemys.Little tip for flash on ANY champ. DONT USE IT TO ENGAGE TEAM FIGHTS.
"UUUUGHH 15 HP AND I CANT CATCH HIM" WELL FEAR NO MORE WHIT THIS ****ING AWESOME SUMMONER SPELL IGNITE.JUST THROW THIS **** IN HIM BEFORE HE FLASHES AWAY AND IN 3,2,1-FIRSTBLOOD!!!!!!!!!!!!

?It's good if you feel like your gonna PWN SOME NOOBS in this game
?On the early game=awesome,mid game=meh,late game=THIS IS ****ING USELESS
?You dont need this you have Q
