CODEX Entry: Miter
The Miter launches high velocity saw blades, tearing apart anyone unfortunate enough to be in their path.
Miter is a saw blade launcher which is used by GrineerEviscerators. This weapon has a charge mechanic similar to the Paris, Paris Prime, Dread, and Drakgoon; the disc must be charged in order to deal maximum damage. However, weaker uncharged shots can be fired in rapid succession as well.
The Miter blueprint in the rewards screen used to show as a Seer Blueprint (screenshot in the gallery). This has since been fixed.
Fully charged shots fired from the Miter do not have projectile width. Instead they behave like a bullet-sized projectile that bounces off the floor of the map. This means that often the player will see the saw blade visibly touch enemies, but not actually apply damage because the center of the blade didn't hit them. You'll be lucky to hit more than 2 or 3 infested with a single charged shot, even when they're packed together tightly.
