Summoning Rules
Stellar Spirit Mages aren't the only ones that can summon things. There are other mages that can summon things called Summoning Mages.
Summoning Mages, as they're name implies, use Summoning Magic. Some things they create may be stronger then others.
Each creature has a certain MP for they're rank when summoning:
E-rank: 5 + 5 to keep active
D-rank: 10 + 5 to keep active
C-rank: 20 + 10 to keep active
B-rank: 30 + 10 to keep active
A-rank: 40 + 20 to keep active
S-rank: 50 + 20 to keep active
Each summoning also needs a spell. Without spells, they will be weak depending on rank. Down below is the amount of MP for each rank spell and how many spells each summon is allowed. Each creature gets a free spell of it's rank. The rest must be paid for.
E-rank: 1 E-rank spell allowed
D-rank: 1 D-rank spell allowed
C-rank: 1 C-rank and 1 D-Rank spells allowed
B-rank: 1 B-rank , 1 C-Rank, and 1 D-Rank spells allowed
