Khrc boss darkside - Boss: Darkside
1Stage 1:
In the first stage Darkside will slam its arm down into the ground creating a small shockwave and also releasing several Heartless. Attack the arm to damage Darkside. Randomly Bloxes will spread out that you can destroy while dodging falling magic attacks from Darkside.
Stage 2:
The second stage has Darkside again pounding his arms into the ground, but this time you need to destroy the 3 Bloxes. This will stun Darkside and he will drop his head. Attack his head to damage him. Darkside will also release a volley of Blox at you from his chest, dodge to the side and then use Fire to blow some of them away for bonus points.
Stage 3:
Darkside is reduced to a single blox. Dodge out of the way of the bloxes that cover Darkside. When they expand away from him, run in and hit him hard. As they start to slow down retreat before they collapse on you. Use Fire to destroy blox for bonus points. - https://www.supercheats.com/guides/kingdom-hearts-recoded
