I am using The Twins from Assist to do this as mine is already P5.

0:00 Stage 2

Sorry, I mess up the order.

For this stage, cast [Catalysed Reaction] then [Polymeric Frostbite] then hit them as many time as possible to trigger Genesis Dmg.

4:40 Stage 1

Quite similar, cast [Catalysed Reaction] then [Shok]. Don't cast during the first round. Save the energy and start casting both abilities every round until the Boss dies.

10:22 Stage 3

Boss counters A LOT, use [Shok] to reduce their DMG by inflicting [Tophor] and use [Polymeric Shield], when they hit the shield, they receive Genesis Dmg and will die.

17:05 Stage 4

[Polymeric Frostbite] twice, then let it attack us while having [Polymeric Shield]

Round 1: Polymeric Frostbite
Round 2: Polymeric Frostbite
Round 3: Polymeric Shield

26:00 Stage 5

Round 1: -
Round 2: Polymeric Frostbite
Round 3: Polymeric Frostbite, SHOK

3 Rounds and they will gain 9 stacks of [Enhanced Armour]. Using SHOK to remove all the [Enhanced Armour] will instantly kill the Bosses.
