Swarm wizard (Formicidae mage)

Some great wizards derive their theories from different schools of magic, or by observing the inherent chaos of the universe. You reject this chaos for the strict order that only unity and shared purpose can bring to a group.

The Formicidae mage uses their skills to harness the collective power of ants, bee's, wasp's or any other swarm type creature. No matter what challenges the universe throws your way you fight back with teamwork, determination, sacrifice and order. Just like the swarms found in the natural world you understand that power comes from the many, not the one.

Hill of Knowledge

Due to your connection with the swarms of the cosmos you have gained new arcane knowledge. Starting at 2nd level, whenever you level up and learn two new spells using your wizard spell casting feature you can choose to swap one of your options from the wizard spellcasting list and pick one from the druid spell list instead.

Additionally, you learn both the mould earth and Infestation cantrips.

Collective Communication

Starting at second level you gain the ability to help others join the network of communication used by swarms. As an action choose a number of creatures up to your intelligence score (minimum of 1) to connect in a telepathic link. You and these creatures can then communicate telepathically to each other so long as they are within 30 ft of you. This connection lasts for 1 hour, until you lose concentration or until you choose to end it.

At 10 level the range of your telepathic bond increases to 60ft.

Additionally, you can communicate in a limited manner with ants, wasps, bees and any other swarm type creature. They can understand the meaning of your words and you can understand them in return.

Unity Amongst Chaos

You’ve learnt how to directly aid creatures through your telepathic link. At 6th level when you or a creature connected to your Collective Communication feature rolls an attack, ability check or saving throw at disadvantage you can use your reaction to prevent the roll from being affected by disadvantage. You can use this feature a number of times equal to your proficiency bonus and you regain all expended uses when finish a short or long rest.

Additionally, creatures connected to your Collective Communication feature gain a bonus to their passive perception equal to half your wizard level (rounded down).

Hivemind Defence

At 10th level you've gained the ability to utilize the collective knowledge of a swarm. When you or a creature connected to your Collective Communication feature fails an Intelligence, Wisdom or Charisma saving throw they can attempt to succeed on the roll instead. Choose a creature currently telepathically connected and re-roll the save using their saving throw modifier.

If the result of the creature’s re-roll is a success it then also severs their telepathic connection.

Fury of the colony

At 14 level you’ve learned how to turn the organized aggression of a swarm under attack into arcane power. When combat starts and you roll into initiative, you can choose to immediately activate your Collective Communication feature.

When you do so in this way, you and those connected to you also gain the following benefits.

• Each creature connected may add a bonus to their initiative score equal to your intelligence modifier (minimum of 1).
• Each creature connected gains a number of temporary hit points equal to half your wizard level (rounded down).
• For the next minute the range of your Collective Communication increases to 120ft.
• So long as you maintain concentration on your Collective Communication feature any creatures connected become immune to the frightened condition.

Once you use this feature you cannot us it again until you finish a long rest.
