These are all the mods you need to speedrun tridolon. If you are not used to the timing yet, use a R13 [Transient Fortitude] instead.

For new players:
Synchronize your cast with the breaking sound right after eidolon starts screaming.

Final phase of each eidolon (all broken limbs):
Cast 4 when the eidolon starts getting up, and 2 when 4's invulnerability timer ends.

Void Strike users:
Transference into [Harrow] when eidolon charged it's scream (moment of silence) > drop energy pad > cast 4 > transference out to operator void mode
Don't equip melee or you'll waste an instance of damage when coming down from archwing.
Stay in operator void mode when not casting 4.
