If you didn't know, tessellation + rebirth + evolution + threaded blast + swarmers + the wanderer creates the most devastating explosions compared to the other subclasses and that includes prismatic.
After severing on hit this setup does the following on kill using the alternate firing mode: Causes a secondary chain reaction explosion, spawns several threadlings that unravel targets, creates tangles which detonate in a much larger and more damaging explosion. Thanks to the wander aspect tangles also suspend on detonation and create more threadlings thanks to the swarmers exotic boots. If you somehow don't manage to kill enough ads in that nuclear explosion you will get your grenade back in no time through the thread of generation and most notably 20% energy per kill from tessellation.
