Support Tank- Cho'Gath

Hope u will comment to help us improve this Guide

|In progress|

Classic ad build, the only diference its the stile of play. To basis you only need the build above

How i play varus its diferent from what ive seen other people play

1st- Normaly these people go mid, treat varus like a caster, only using their Piercing Arrow most of time

2nd- Normaly people used to other ad carrys hate his Piercing Arrow, so when playing him they dont even bother to use it efectivly when using it at all

->How i use him its very simple:

Start- put 2 points in Piercing Arrow, and fire it when u can. It will have great damage and realy zoning out your enemies

Laning phase- Now your Hail of Arrows starts to shine. Land it (preferibly on smartcast) and stack 3 times your w. Then u can stay back allitle and snipe with Piercing Arrow to deal a great deal of damage

Late game- you are just like any other ad carry, stack your w then blow up. (Teamfights are described below in varus ulti)

Q Piercing Arrow- Praticly a sniper, deals "TonZ Of DamAgE" to anyone on its huge range in a line

W- Every auto atack deals extra magic damage and stacks blight with a maximun of 3 for 6 seconds. all other abilities will detonate blight to deal aditional magic damage

Varus ultimate: Chain of Corruption

-When used in a teamfight, u can realy change it around. If you see someone out off plance just fire it and you will see everyone atached to the ground vonerable to your team atacks

-one good way to use it its to hide and let them push, then use it (preferebly beneth the tower) to stack your w, then when they can move use your Hail of Arrows to blow the stacks and put another 3. If they are not dead yet, just use Piercing Arrow to snipe them blowing up your stacks

Using Cho´Gath has a support its good because he has "free health"(ulti) to late game, it has good sinergy with Varus because lets him apply stacks with Rupture and it still has a silence

+ gives u a nice way to stop their team ad carry or to help someone flee and still having that flash for a more dificult situation

Defensive Runes

Skill Sequence
Rupture- After a brief delay, u will trow enemies into the air dealing magic damage. Very good to let the ad carry get some shots, in Varus case, it will alow u to put an extra 2-3 stacks (1st priority)

"feral scream"- Gives an amount of magic damage and cilences the target. This is realy good to dont let enemies get away or casters to do anything (2nd priority)

"vorpal spikes"- It ads spikes that go in a cone infront of Cho. This doesnt have much efect on support, but does help get a bigger amount of minions low hp and may zone out enemies (take this only when u need to)

Feast- U eat an enemy and deal a large amout of true damage. If the target is killed, u grow larget, increased range and get an amout of health. 6 stacks Max
(take this wenever u can)
