The Light Beast casts a shield that decreases the received damage and increases the inflicted damage. This shield shares the damage inflicted on the Light Beast and substantially decreases the inflicted damage when receiving multiple hits.
FRONTLINE:
Obviously you should use colleen, because you need Attack buff. You don’t really need other supports, just BIG single target damage dealers. As second front liner you can use Mei Hou Wang, Xing Zhe, Laika or other DPS that don’t get oneshotted.
BACKLINE:
In the backline you should just go with non-multihit Damage Dealers. The best mobs for this role are: Lyn, Brandia, Luna (Dark Pierret), Bethony (Dark Magical Archer), Mara (Dark Amazon), Lushen, Perna ecc.
Just pump up your damage and you will have 0 issues.
Good luck
