M1- 14 damage, heals 2 on hit and applies Corruption- reduces damage and healing by 15%.
Great auto attack. Weaken is really strong right now and having it on aa is great. It isn't the easiest aa to hit, its quite slow but has huge value. Always use this when in downtime, but watch out for counters as while it is flying it begs for the enemy to hit counter.

M2- 1sec cast time, 22 damage, applies Judgement- increases damage taken by 15%.
Always try to have this debuff on the target. It enables you but also your teammates. At the end of the round a good placed Judgement on a focused target could result 60+ bonus damage.
For BLC players, this ability could feel strange at first. You just need to get used to the fact that Inhib lost alot of his mobility with the revamp and later rework of Varesh.
Ex M2 - 14 damage, 6 heal, both debuffs. Nothing more to say here, it has a quicker cast (0.5s) and is very rewarding to hit, but costs 1 energy. Helps your sustain alot vs every matchup.

Space- 28 damage shield to Varesh or ally. Nothing special here. BLC players will miss old space.

Q Counter - basic counter, activates after getting hit by counterable attack. Lets you teleport to chosen location. If you teleport next to an enemy with corruption or judgement you consume them.
Consuming corruption heals for 6 and inflicts short snare.Judgement silences the target for 0.5 secs.
This ability is great. Most times you will have corruption on atleast 1 target and this ability enables Varesh to dive and be tanky.

E- spawns circle on the floor. Explodes after 0.7 sec, deals 12 damage and consumes Varesh's debuffs on the enemy. Consuming corruption heals for 6 and inflicts short snare.Judgement silences the target for 0.5 secs. Easily his best ability.Enables him to have so much control over the game. His Ex E spawns a bit bigger circle that knocks enemies back.

R- dash, spawns E under enemies it passes through. Use it to chase or escape. Good for consuming debuffs.

F- iFrame dash, deals 24 damage and applies both debuffs,continuing up to 3 times if it connects to target. That means consecutives would deal 28 damage. Easily dodgeable, so use it after enemy burns all escapes.

Playing Varesh you will realise he is best played as a burst and diver to punish mistakes.
Use your Ex E to get melees off you and on orb to get it closer to your team.
While dashing with R and F you pickup heals, energy and teammates energy. Your R and F also work on orb! Use it to spawn E under orb with R or to continue F spree by hitting orb.
As a rule of thumb try to keep your Judgement on the target while he has escapes and silence chain him while he is vunerable. Never use both your escapes. With his revamp, Inhib lost so much mobility. Without his counter or R, he is a sitting duck.

If you come from BLC, you will either hate Varesh or love him. Some say he has become super weak and he has no chase or mobility now, but that is not true. A silenced enemy can't use escapes to run from Varesh. That also means Varesh now fills the role of an enabler. He is definitely the hardest champion to learn in the game atm, but has serious outplay potential at the very top.
