Magnus

Skewer destroys trees which can be useful against certain heroes.

When fighting close to pillars and cliffs, consider Skewering opponents on them.

Magnus has huge base damage that is further amplified by Empower. Use to win the lane last hit wise.

When an opponent is close to your tower, consider making Shockwave into Skewer play.

Ask your teammates to make stacks for you as you can clear them with ease once Empower is maxed out.

Consider turning during Reverse Polarity animation to be able to Skewer stunned units towards allies right away.

Don't rotate too much. Focus on farming Blink Dagger and then start playing more actively.

Once you have Blink Dagger, make use of it immediately before opponents are able to scout it.

Avoid showing yourself at the start of the fight. Wait for opponents to clump up and do your combo.

Pick up Aghanims Shard later in the game to boost your farming speed, damage output, and control.

Be careful not to get Skewered by Magnus under the opponent's tower.

Empower is a great farming buff for Magnus and his melee cores. Contest their jungle and block camps.

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

Avoid fighting in choke spots and clumping up against Blink Dagger into Reverse Polarity combos.

Reverse Polarity has a long cooldown. Look to fight opponents when it is down.

Status resistance items shorten the disable duration of Reverse Polarity.

Having Aegis on a core hero is a protection against Reverse Polarity. Kill Roshan on the first chance.
