Sage

[C] Barrier Orb can be combined with [X] Resurrection to ensure your teammates safely revives.

Sage's [C] Barrier Orb is great for denying pushes on defense and for splitting a site on attack. The wall is very fragile before it fortifies, so try to wall in situations where it won't instantly be broken.

[C] Barrier Orb can be used to boost yourself or teammates by casting the ability under yourself or teammate(s).

Sage's [Q] Slow Orb is one of the best combo abilities in the game, especially when paired with damaging abilities like mollies or grenades.
