Glaive is a very versatile hero. You could play him as a jungler, laner, or captain/support. His first ability Afterburn (A) Glaive rockets in the target direction, damaging enemies along the way. His basic attack knocks people away and stuns them for a short period of time. His second ability Twisted Stroke (B) Glaive instantly executes a critical strike. This ability deals weapon power, it can also deal crystal power (if you go crystal power). It triggers basic-attack effects. Lastly, its passive increases critical-strike chance and AOE-cleave damage of basic attacks.

Finally, his Ultimate, Bloodsong (C) Glaive swings his axe in a circle dealing area damage that increases with the number of stacks used. This ability removes all stacks. Glaive generates Bloodsong stacks from basic attacking or from receiving basic attacks (max 20 stacks). Each stack grnats Glaive bonus lifesteal.

In the early game, it depends on the position you are playing. If your a laner, I suggest playing aggressive by using you A ability to punish enemy trying to get cs (minions). As a jungler, you would do the ordinary jungle camps and ganking lanes. When your ganking, I suggest diving in by using your A ability then knocking back enemies to your allies to potentially get a kill. If you are a captain/support protect your laner, and use your abilities to be aggressive against the enemy.

During the Mid to Early Late Game, as Glaive you would be pushing in lanes by destroying turrets. In Teamfights, Glaive is not really tanky, so I suggest just attacking the enemy carries with your high damage output and using your E ability to get a massive health boost to survive. If your going for a more tanky/support build use your abilities to damage enemies and get your carries fed. Some people randomly do Blackclaw or Ghostwing while the enemy team is still alive. I suggest doing these objectives after winning a team fight, and the majority of the enemy carries are dead (at least 2 or 3)

Vision is really important and key to winning a game. As any hero in Vainglory you need to be constantly putting down scout cams. I promise you this will be very important to winning a game. Vision of the map or some areas of it gives you information of the enemy. It shows you if the enemy jungler is going to gank a lane or steal a camp from your jungle. Where enemies are on a map. If they are going to do objectives. These are all key information you should know. Some main spots your should puts scout cams are in the bushes in the river, the enemies jungle, or Ghostwing or Blackclaw.

[*] Use your A ability to go through walls or obstacles on the map
[*] Use your Ultimate in teamfights to gain bonus health
[*] Use your A ability to knock enemies into your team for any easy kill
[*] Use your E ability to finish of opponents
[*] Glaive isn't tanky so try to pick off the enemies and back off
