Doom

Bonus gold from Devour is granted at the end of the Devour cycle and you will lose it if you die.

Once you get Blink Dagger, try to make use of it immediately before opponent see it in your inventory.

Usually you want to devour Centaur Conqueror and obtain War Stomp to disable opponents after blink and cast Doom.

Avoid showing yourself at the start of the fight and wait for your Doom target to show.

Avoid fighting while Doom is on cooldown. Push out lanes or play defensively.

Check opponents' inventories for Linken's Spheres and Lotus Orbs. Be careful not to drop Doom on those.

Look to use Devour as frequently as possible on lane creeps or neutral creeps to maintain your armor in the lane.

Doom is a weak laner at lower levels. Pressure him early on.

The Doom spell has long cooldown. Look to play aggressively when it is down.

Linken's Sphere, status resistance items and Lotus Orb are good at dealing with The Doom spell.

Acquiring Aegis for your core is a good way of dealing with The Doom spell. Look to kill Roshan.

Until Dooms level 25 mute talent, you can still use your own items to kite or escape while Doomed.
