Combination Attacks are special attacks in Spectrobes and Spectrobes: Beyond the Portals. They combine the properties and abilities of both Spectrobes in combat to unleash a single, powerful attack on every Krawl on the field. A Combination Attack cannot be executed if one of the two Spectrobes has fallen in battle. There are nine main combos, one for each property duo at Adult and Evolved stages. For the Adult stage combos, the chosen combo is the dominant (i.e. advantage over other property) property. If an Adult stage is combined with an Evolved stage, it works as though both were Evolved.
