This is the Life Fiddler. This is a way that I play. So this could be more of a advice thing.... yea...

Main Skills are Terrify and Drain.

The beginning is a little slow. But after about 10 or 15 minutes of good play, I'm usually killing or scaring away most opponents. I'm not very good at explaining things, so stick with me here.

First of all, Kage's is an optional item which is why I put it at the end. Added for the increased income.

Second, when you have the money to buy something, buy it! If I am on a roll I like to keep going and buy at deaths/heals only.

Doran's Ring: The first item you buy. Duh

Catalyst The Protector: When buying the items (Ruby and Sapphire Crystals) you should buy the Sapphire crystal first since Drain is your main skill. With the added Health and Mana bonuses you also restore life when leveling.

Blasting Wand: +40 AP... what more can I say?

Rod Of Ages: Good weapon with good bonuses can't go wrong with it sense it gains bonuses as time goes by.

The next item purchase is your choice

Warmog's Armor or Rabadons Deathcap.

I like to choose the Rabadons Deathcap first, as the +155 AP is a killer boost to your current prowess, and after that, you gain another 30% AP boost. Even better, when you buy items that increase your AP, you gain extra AP as the passive ability increases by percent.

Warmog's Armor: +920 health... By the time you get this you should have over 2.5k maybe 3k. this armor also gives you +30 health regen. This mixed with your Drain skill and you are Healing non-stop. Keep killing all the minions your can to stack the bonus to max.

Void Staff: This gives you +70 AP and +40% armor pen.

Your main skills are Terrify and Drain.

The Ult skill is there to help with the big groups.

After you have the bulk of your AP, drain will do enough damage to keep you alive, and at level 5, it will last nearly as long as the cooldown, allowing you to run a full chain of drain. In between drains you can cast your Terrify skill followed by the dark wind skill then continue draining.

Once you get the Ult skill Crowstorm the bushes and jungle become your friends. Try to come out of the jungle behind your opponent but keep the enemy just a little bit out of the Crowstorm range and Cast it. As soon as you appear next to your victim cast Exhaust followed by Terrify and then drain the life out of them. Try your best to not cancel Drain, and let the victim run out of the range of Drain. If your life is dropping faster than you can heal, then run back and heal.

Since the Ult skill takes a while to cooldown, I didn't make it the main skill. Drain is far more efficient when draining over 300 a sec and doin even more damage the few seconds the Ult is going.

There is not a lot to this build as of right now. I will update this as I continue to play and learn.
