This is my first build guide please comment with suggestions.

Fiddlesticks is great against most of the champions unless they have stuns or silences or anything that will interrupt your drain.

I would say max your drain first because when in 1v1 combat your drain has a max cast time of 5 seconds and at level 9 max drain your cool down is 6 seconds if you get blue buff you can constantly be casting drain at level 9. The skill I like to max next is terrify so that your enemy can’t run away. I don’t use dark wind as much as drain and terrify so I max this last it is a very nice skill to have for the silence and that last hit to kill them before they go away.

the items that I have as my six change from game to game but the most commonly used items are mejai's soulstealer if I’m getting kills early game it can give me lots of early ap, will of the ancients for the spell vamp and ap sorcerer’s shoes for spell pen and movement speed, the last two items very I either go spell pen and ap or cool down ap or health ap generally I prefer health + spell pen.

I generally use flash for summoner spells so I can get away if I’m out matched or if I don’t have quite the reach I need for my ult. I use either teleport or exhaust for my second spell and if I notice mana issues I change it to clarity. Teleport is for quickness with max xp and in the fightness, and exhausts to slow the enemies down so I can kill them.

the things about this build are lots of ap so you can get tons of health and deal lots of damage but if you get silenced and or stunned there isn’t much armor to protect you so very squishy unless casting drain.

I know this isn't a complete guide maybe I'll make one at a later date, but not enough time right now.

Please leave a comment with your opinion on the build and suggestions thanks.
