Typhoeus can play as a DPS alongside INT form Arcane, but note that this will be incredibly SP hungry to play. Arcane can easily stack Nature Inflictions with 2 of her Battle Skills, dealing high damage to enemies in an AoE while setting the stage for Typhoeus to gain her Sign stacks.
Liino buffs the whole team with her Battle Skill or Ultimate, while Perlica or Ardelia can debuff enemies with Electrification or Corrosion that can also trigger Liino's Combo Skill.
