Rune

Rune is a Celestial boss that was added on 31 May 2021.

Design
Rune has three shells, each of which rotates. The middle shell rotates counter to the other two shells. The bottom shell is a nonagon, and has a Giga Trap launcher on each side. The middle shell is a heptagon, and has a minion spawner on each side. The top shell is a pentagon, and have a Redistributor turret on each side.

Technical
Rune fires very strong traps and minions, as well as nearly-unstoppable stabilizer bullets. Rune was slightly nerfed the day it was released during a livestream by Oblivion.

Countering
Rune is an extremely formidable boss. Its stabilizer bullets are fast and instantly kill any tank they hit, while the minions have high range and can overpower solo players. To kill Rune, have a large number of Twisted Hybrids, Fusiliers, and other high-DPS tanks hide behind a number of large Rocks. Rune cannot enter the rocks as it is too large and too slow. Therefore, use tanks like Professor, Redistributor, and Overload to penetrate the traps and hit the boss directly, as the redistributor turrets will be focused on tanks behind the rocks. If there are no good Rock areas in the server, use Shooting Star or Rammer to distract the redistributor turrets.
