Here is the quick and easy way to beat Atheon in Vault of Glass using only a Titan. This awesome feat was completed by @Auth using his level 28 Titan Alt, two grenades, and a charged Ultimate. ( @Auth, feel free to elaborate on the exact specifications)
There is a video of the whole process in action at the bottom of this guide.
- Have everyone else in the party run to the Left or Right and stay out of Atheon’s line of sight. Take your Titan straight towards where Atheon is beginning to spawn. Aim towards the left side.
- The goal is for you to aggro Atheon and entice him to walk between this rough stone and the first pillar.
- Here is a closer look
- Take your time and lure him around.
3.) Toss your first grenade in front of him ( you should aim at the patch of grass at his feet)
4.) As he begins to back away from the gernade blast, Toss the second one at his feet.
5.) Let loose with your Ultimate right in front of him while he is still reeling from the second grenade blast.
6.) Watch him fall to his death, do a little dance and collect some awesome loot.
Now you know and knowing is half the battle!
