Happy you're enjoying the game!
A mergign refresher:
- Select two spirits. First spirit will stay and be boosted, second spirit is consumed.
- Boosted spirit will get 50% of absorbed spirit's EXP, as well as all compatible skills.
- Captured spirits come with a random array of skills (within the pool they can learn), so catching the same spirit and merging them is a viable idea.
- All you have to pay close attention to is who you select first and last, and maybe save before merging in case you mess up.
- You cant see the skills from the merge menu (a known issue) but you can check them from he regular main menu.
- Not all spirits can learn all skills, so again, save before merging just in case.
That's all really. There was no time to polish for more.
Hope you enjoy the game as unpolished as it is, and we can show even more in the future.
