School of Summoning

You are practiced at summoning creatures.

Summoning Savant

Whenever you cast a spell that summons/conjures creatures, it expends a spell slot of a level equal to the spell's level minus one-third of your level in this class rounded down. However you must still be able to cast the spell at the level you want to cast it. Example: casting summon greater demon (4th level) you are 10th level. It would expend a 1st level spell slot. Also whenever you cast a spell with material components it does not require material components without a cost.

Continus Summons

Whenever you cast a spell that summons/creates a creature, that creature remains until it is reduced to zero hit points instead of how long it normally remains and you control it forever.

Extra Creatures

Whenever you cast a spell that summons/conjures a creature, the spell creates 1d6 times the number of creatures it would normally make.

Powerful Cretures

Creatures summoned by your spells have double maximum hit points. Also, they add your spellcasting ability modifier to their attack and damage rolls. Their attacks are also considered magical.

Master Summoner

Whenever you cast a spell that summons/creates a creature roll 1d20 then create a number of creatures with a challenge rating equal to or lower than the number rolled. the number of creatures you create is equal to the number rolled.
