Maybe? I doubt it they said there are 48 combinaisons so.
4 Elemental skills x 6 Non elemental = 24
24 Base skill but your source skills also have their own results.
So double that and you already have your 48 skills.
The spider skill may be simply be a plain Geomancer skill.
That makes me think, ... you could have a 4 summoners party, all with a different elemental secondary spec.
So that mean you have 8 characters each fight !
