You can summon elementals, undead, beastial spirits, or planar entities simply by rolling your Arcane Skill check. Each creature added to the summoning after the first adds 5 to the difficulty for small/medium and 10 to the difficulty for Large/Huge. Maximum amount of creatures summoned each spell (called a batch) is your Intellegence Modifier. Summoning a creature/creatures takes one FULL ROUND. The Creature/s appear up to 30ft. away from the caster and may attack immediately upon summoning. Stats on the creatures come from 3.5 D&D.

Every time you use a summoning spell, the creatures summoned is considered a “batch”. It takes a swift action to direct the “batch” to move and attack a target. If a batch is not directed within a number of rounds (Int. Mod.) then they sense they are no longer needed and fade back to where they came.
