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:
 | 5/5 | perfect to give Sigurd or Nova a respite until they ult, and prevent stun from Solaris, ice age and others |
 | 4/5 | was the best before Tidus, but a bit redundant nowadays, in my opinion |
 | * | this totem is useless with Sigurd, but mandator to let Nova tank, especially to prevent the light totem in earth+light |
 | 5/5 | get a shield whenever the totem heals you, very good synergy with the totem |
 | 4/5 | you 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:
 | 5/5 | very effective against earth, or to kill light before they ult. Coupled with your totem, it will take very little charging to one-shot enemies |
| 4/5 | allows Moloch to keep stunning after he dies, which sensibly impacts the team's lifetime |
Earth
There are several valid choices of fusion skills, which depend on your exact team and opponents, but those ones work well:
| 5/5 | the most popular choice, it strengthens the earth totem |
| 4/5 | usually a bit less effective than murmur of the crags, but still effective |
| 3/5 | allows Angus to keep his ult after he dies |
 | 4/5 | very good synergy with Avalon, best choice here |
Light
| 3/5 | allows you to heal during your immortality; best choice for light but not tremendous |
Dark
| 5/5 | lets you double down on offense - effective because dark must kill fast to win |
| 4/5 | dark has a good amount of health, so they can stand until the healing finally triggers |
| 4/5 | vampirism yields many healing ticks, so good synergy |
All Teams
Those ones are best used on secondary totems, typically light or dark.
 | 4/5 | useful against Araji, Tenebris and every team but earth |
| 4/5 | great with Angus, Moloch or Novatank. With Brustar, Sigurd or Rigel, they will just help you trigger the totem faster |
| 4/5 | good with all teams: it introduces a welcome randomness and hastens the totem trigger |
 | 3/5 | may allow one of your titans to survive when he ults under heavy pressure - usually not the tank though |
 | 3/5 | this bonus is not big but it is enough to make a difference against specific opponents - I use that on my F+L |
 | 3/5 | one stun and |
Two-totem teams
One of the two totems will always activate before the other, based on your titans' position in the team.
Therefore we place active skills on the first totem to activate, and passive ones on the other.
Note that bonuses from two copies of the same skill do NOT stack. At best you will refresh the duration of the buff.
