Best Fusion Skills

Recommended fusion skills for each element. Choices depend on your exact team and opponents, but those ones work well.

Water

There are several valid choices of fusion skills, which depend on your exact team and opponents, but those two skills often form an excellent synergy:

Murmur of the Cragsperfect to give Sigurd or Nova a respite until they ult
Triple Cycleget a shield whenever the totem heals you, good synergy
Primal Zealyou may have a chance to keep Sigurd alive, but triple cycle is likely better

Fire

There are several valid choices of fusion skills, which depend on your exact team and opponents, but those ones work well:

Flame Dancevery effective against earth, or to kill light before they ult
Last Flashallows moloch to keep stunning after he dies
Ice Agevery useful against some combos, but not earth
Call of Elementsstrengthens the already good damage of the team

Earth

There are several valid choices of fusion skills, which depend on your exact team and opponents, but those ones work well:

Flame Dancegives earth what it lacks the most: offense
Murmur of the Cragsstrengthens the earth totem, not bad
Echo Aegisvery good synergy with Avalon

Light

Light is often used to keep an elemental team alive, so we usually choose fusion skills to support the main element. Moreover we often put active skills on the main totem since it ults first, and put passive ones on the light totem.

Last Flashvery good with Angus and Moloch
Ice Ageuseful against Araji and others
Primal Zealvery good with all teams, since it means more totem activations

Dark

Dark is typically used to complement an elemental team, so we usually choose fusion skills that suit the main element. Moreover we often put active skills on the main totem since it ults first, and put passive ones on the dark totem.

Last Flashvery good with Angus and Moloch
Ice Ageuseful against Araji and others
Triple Cyclevampirism yields many healing ticks, so good synergy
Primal Zealvery good with all teams, since it means more totem activations
Call of ElementsTenebris can benefit from this one
