Not sure if it was good move or not. But in the beta I had quite a many spirit slots. So yesterday I invested 50 points (3,45€
and used them to 25 spirit slots. Now I got 45 spirit slots.
Iam still thinking thats not enough. When merging Iam using only same colour and if possible same spirits and thats the reason why so many slots. Kinda hooked to this game again (long wait after beta).
If I get more destiny orbs as rewards, Ill save them to future pack use (Toro & Kuro pack). But I might spend another 3,45€ and invest it to spirit slots.
At somepoint in this game player has multiple SR / R spirits which are so valuable that player dont want to merge / sell them, so your original 20 slots are going to be pain, if not upgraded via dorbs.
Bleh still ~7h before I can play this game more. Add me to your DoS friendlist, only got 2 players there so atm 8 free slots!
Edit: Great blessing vs Bad luck
