Pact of the Invoker

unlike many other warlocks who make a pact with one powerful entity, Invokers instead make deals with many types of creatures reaching across the planes to summon the different creatures that you have made pacts with to come into your aid.

Caligian Pact

You form a pact with a weak planar creature, you can choose it to be celestial, an elemental, a fey, or a fiend. The creature takes the form of a CR 0 creature of the chosen type. If the creature dies you can perform an hour long ritual to resummon the creature from it's home plane. At 5th level it can take the form of a CR 1 or lower, CR 2 9th level, CR 3 at 13th level and CR 4 at 17th level.

Cocytus' Knowledge

When you make an ability check to recall knowledge or interact with a creature that originates from outside of the material plane, you gain advantage on the check.

Summons from Purgaturio

Your knowledge and capability of how to summon creatures from other planes has grown much more powerful than that of an average conjurer. Any creature summoned or created by a spell that you cast gains the following benefits:

• The creature appears with more hit points than normal, it gains hit points equal to your warlock level.
• The damage from its natural weapons is considered magical for the purpose of overcoming immunity and resistance to nonmagical attacks and damage.

Spell Casting of Mechaba

Summoning spells are such second nature to you now that you can passively empower them beyond your regular limit. When you cast a spell that summons a creature you can treat the spell as one level higher.

Elysium Concentration

You are able to accomplish feats that nearly no other caster can. Once per long rest, while you are concentrating on a spell that summons a creature you can cast another spell that summons a creature with a different name. You can concentrate on both spells at the same time however you have disadvantage on concentration saving throws while doing so. Additionally once you lose concentration on both spells you gain one level of exhaustion.
