How do you do dungeons with blu mage?

[Neophyte]

Get, 4 BLU. Big pull. Fully buffed Self-destruct (Toad Oil, Peculiar Light, Moon Flute and Bristle). Repeat until boss, pull boss and have the room locked so the ressurected BLUs teleport inside the arena. That's the fastest way me and friends found to run throught dungeons. This strategy one shots every big pull until 2.5 dungeons. Always undersize even at 50 to avoid ilv Sync.

You can do it solo too but you've to Ram's Voice the trash before you turn off Mighty Guard to explode yoruself and walk all the way back without using the Boss room teleport.

You can also use a fully buffed self-destruct right at the start of a boss. If you explode on like the 3-4th GCD you can still teleport in after respawn, killing bosses in seconds if 2-3 BLUs do that.
