I can give you options here.
Summon lvl 3 - 5 = if you prefer Salamion but depending on your preference and build stat, you can assess if the added int damage is worth it or not.
Summon Familiar lvl 5 = because you are WizC3
Summon Salamion lvl 1 - 2 = you can put no points here. He is another tank with very bad ai and low damage. It depends on your preference, you can add 1 - 2 points here for the duration. He is good only at C2 with the attribute to add status ailments on his target.
Summon Servant lvl 5 - the added +dark magic at lvl 5 buff complements your summon familiar.
For personal choice
Summon Devil lvl 5
Summon Familiar lvl 5
Summon Servant lvl 5
