Overview

Double Dragons is a great team comp for those aiming for a high arena score due to this comps high base stat total.

This comp is centered around Nowi and Tiki, a strong red+blue core with considerable bulk.  Nowi is great against opposing blue mages and non-Falchion reds while Tiki is incredibly tanky.

Strengths
  • Strong damage
  • Tanky core
  • Versatile skill sets
  • Counters regardless of enemy position with core (With Tiki Adult)
Weaknesses
  • Weak to Falchion
  • Low attack range core
  • Low mobility
Recommended Setup
Synergy Units

This team comp has some amazing strengths and some glaring weaknesses. To balance the team out, you need a ranged nuker that can deal with falchion users or the enemies ranged units. You should also bring units that buff or can shove your core units into the enemy team for quick takedowns on high priority targets

Hero

Abel
Abel
Great option
He is a good counter to sword users with great mobility for the more aggressive style of play, but he struggles below 50% HP.
Gwendolyn
Gwendolyn
Similar attack buff and attack debuff as Sharena but her low speed is what keeps her out of the meta.
Oboro
Oboro
Good answer to Armored units like Hector and her defense debuffs is useful, but without an attack buff she has little synergy with the double dragon core.
