I was wondering if anyone knows if there's any correlation between your level and how many slots each piece of armor has? I did the first set of Squid amiibo challenges for that predator head armor and it has 3 total slots for abilities but I've seen some with 4. I was about level 7 when I did that and haven't done any since (I'm currently level 10) but I've been scared to try for more on the off chance I can get 4 slots on the rest of the amiibo armor pieces. Don't suppose anyone knows for sure whether they all have 3 and that guy just added a slot to his via Spyke?
