Hello! This is my first guide I have made, so please leave me your feedback and I'll try to make my next guide better! Now this guide I will be explaining is a lifesteal nasus. Now before you leave the page because I know, it sounds stupid, let me tell you a few things.
- When you farm your siphoning strike at the begining, it gives you life back according to your lifesteal, so when you use it with this lifesteal build, you deal tons of damage while getting tons of life back.
- When you get silenced and you can't cast anything, just basic attack everything.
Yes, this build is a little troll, but the first and only time I saw it in a real game, the nasus got a quadra-kill. That got me thinking and I realized it is alot better than you would think; so let's get started!

You always have to have a little bit of survivability, so those armor/magic resist runes will really help with your first blood early game. I chose those quintessences because, well, hey, a little armor penetration never hurt no one right? And with the marks, you have to have a little damage early game for your siphoning strike.

These masteries are just something I came up with on the spot, I don't really put these into consideration to much, but the lifesteal helps add to this build, and the armor and magic resist are for, again, the early game/first blood deal. The rest of it just follows in to a classic nasus.

The items are pretty self-explanatory here, you want three bloodthirsters because they really help out with damage for your siphoning strike and the lifesteal helps with the whole point of this build. the executioners calling is just a nice, cheap early game item with a good amount of lifesteal, and the wriggles lantern is just sort of a survivability/lifesteal item I like to throw in. If you don't prefer it though, it can be easily replaced with a phantom dancer for attack speed and movement speed. Same reason for those boots, the attack speed helps you get life faster with your lifesteal, and the movement speed is pretty self explanatory.

You always want to start out with one of everything first before you max anything, but after, you want to max out your siphoning strike. And from there, just follow with maxing your spirit fire, then wither. And obviously, get your ultimate whenever you can, at level 6, 12, and 16.

I highly prefer these two abilities, because they help you get around a lot quicker. But, I just like movement speed. You can also do Flash/Ignite, your Teleport/Ignite. You can experiment with this one, but those are the only three combinations I have tried with this build.

Okay, this part is explanatory for those of you that have read the abilities, but if you havent, every time you kill a player/minion, you get 3 bonus damage on your siphoning strike, so you always want to last hit with it. And remember, do this late game also, it stacks infinate amount of times, so don't worry about capping it. And, last hitting is a good habbit for getting those bloodthirsters up. I personally like to jungle after I get a bloodthirster, because it helps get stacks right away instead of dealing with your teammate in your lane, or your enemy killing you.

Pros:
- You rarely die with this build if you can get it done rightl
- Your siphoning strike will give you life according to your lifesteal, so this is a huge advantage.
Cons:
- You don't get alot of damage with this, so don't expect your siphoning strike to do AS much as it would in a regular nasus build.
- Against ranged, you are almost useless because you can't catch them and you don't have alot of survivablility.
