Summoners War: Chronicles

He starts off as one of the 3 attributes. Certain skills will make him destroy the pillar he has elemental advantage over. Hitting the other elements will cause an explosion that does a lot of damage.

For his fire phase, there will be a text popup that says "Farakel is watching someone. Make him destroy the origin of wind. You will see a giant red circle target on the summoner being targeted. That summoner needs to stand next to the origin of wind pillar and he'll attack in that direction.

For his water phase, there will be a text popup that says "A blue hole will appear when the Source of Erosion applied by Farakel disappears. Make him destroy the origin of fire." You will see some water under the summoner being targeted. A pool of water will appear under that summoner that will do damage to the Origin of Fire pillar.

For his wind phase, there will be a text popup that says "Farakel unleashes divine punishment. Make him destroy the origin of water." He will summon an AoE that stuns under all summoners for a short duration. Just keep running, but one summoner will need to run under the origin of water pillar to damage it. STAY AWAY FROM THE OTHER PILLARS.

When Farakel has about 40% HP left, it will summon 3 portals. Press F on the portal to teleport into a mini arena with a single enemy. Kill the enemy to give Farakel DMG TAKEN UP then teleport back to the main arena to fight Neutral Farakel.
 

Neutral Farakel has all skills and passives from all 3 elements. Try to dodge everything you can because the water passive heals him for 100% damage dealt to you. Stay alert for his Absorb attack! He starts getting damage increase every 30 seconds after the T-7:00 mark.

Team suggestions: 1 debuff-based damage dealer (Argen/Narin/Kro), 1 healer with debuff remover (Ariel/Lulu) or immunity (Shushu), one utility buffer/debuffer (Kroa/Bastet/Tesarion/Verdehile/etc). Movement speed buff is good against wind Farakel.

I don't suggest putting multiple roles in at once in case there is an AoE wipe. For example, if Argen dies in an AoE attack that wipes all your monsters, you can still bring in Narin Ha as backup.
