Hi, I'm hoping that you liked my build so far i'm just going to tell you a few tips I know about Swain I hope this will help

For some people who dont know when a good time is to use your ultimate, it's normally best to just use it either when your about to kill someone so its an easy killsteal or when your about to die because it heals you alot, The reason why I put will of the ancients is because it helps with your ultimate and your other spells too

It is good to make sure your not wasting all your money on ability power other things that are good can be mana/regen spell vamp health armor things like that because he is abit of a tank aswell as a mage,

The reason why I got philo's stone first is because he tends to run out of mana alot especially when he is using his ultimate, so this helps with being able to keep it up for longer

I suggest in the very late game replace your sorce boots with a radabons deathcap just to get the kills up a little

The reason why I didnt get soulstealer is because with swain i need to focus on other things like i said before

That is all hope you enjoyed my build
