A genetic trait that allows for greater freedom in fusing.
Fusing is typically limited to:
- MonsterGirl + MonsterGirl
- MonsterGirl + Spirit
- Creature + Spirit
- Creature + Same type Creature
This trait allows for:
- Creature + Any Creature
- Creature + MonsterGirl
- Spirit + Spirit
This trait is extremely useful in acquiring breeding pairs, creating specific skillsets, and in particular, evolving Celestials.
For example, you have a creature you only have one of, but wish to breed.
With Catalyst you can fuse a MonsterGirl with that creature, and you would then have a MonsterGirl/Creature that could then be bred with other MonsterGirls to produce another MonsterGirl/creature, and those two then have a 1/4 chance to produce the original creature.
This is a good way to acquire a breeding pair of Seals, or very rare creatures like the Kraken.
It is also a way to get powerful creature only inheritable skills from creatures to MonsterGirls.
