Top 5-

1.Spire is best in closed spaces so try to get in a small arena that has lots of walls.

2.With the Magmaul shoot right under your opponent for maximum effect because magmaul bounces.

3.Spire can roll up walls use that to your advantage(get to a good sniping spot)

4.Don't burn yourself with the Magmaul it looks so foolish.

5.Recommended arena: Proccessor Core
