Slardar

Keep an eye on Bash of the Deep charges and preferably bash the opponents.

Use Slithereen Crush and Bash of the Deep to secure ranged creep last hits.

Run through the river as much as you can when you are moving around due to extra movement speed.

Build up Bash of the Deep charges up to 3 ideally, before making a move or gank attempt.

Once you have Blink Dagger, make use of it before opponents are able to see it in your inventory.

In fights, play around your right-clicking core. Jump and Corrosive Haze the target he is able to hit.

Slardar enables the team to take Roshan down fairly early due to Corrosive Haze.

After every 3rd hit, Slardar will have Bash of the Deep charged up. Keep yourself at distance.

Be aware of Slardar's Blink Dagger timing. Look to cancel his Dagger in the fights.

Items that provide dispel are great against Slardar's Corrosive Haze.

Armor items are great against Slardar's damage output and armor reduction.

Slardar lineups are able to take Roshan early on. Ward around Roshpit and check.
