Vandras Academy of Necromancy

This Subclass is focused around a being a competent scholar, that helps preserving Civilisation from Danger.

A Person of Society

You gain  Profiencies in the skills of: Nature and History.  If you are Proficient already, you can choose to gain expertise instead.

Worker of Society

Starting at second Level, when ever you take a Level in this class, you can increase your maximum HP by 1. 

Undead Labour

Creating an Undead Summon, only Requires a corpse, no other material cost.

So much to do

Beginning at 10th level, when you cast a spell that requires concentration, you dont have to concentrate on it, to keep it running for up to 1 hour.
This doesnt extend the duration of the spell.

Once you used this feature you need to perform a short or long rest to use it again.

Loyal Servant

Starting at 14th level, when ever you summon a being, you can forge a magical pact. That being is now called your "Loyal Servant".

This pact allows you, for the duration of the summon, to perceive the surroundings through the senses of your "Loyal Servant". This doesnt not blind you to your own senses. You also cant loose control over your loyal servant, as long both of you remain on the same plane of existence.
Both of you can communicate by a telepathic connection over any distance, as long it is your "Loyal Servant"

You also can cast spells from the position of your  "Loyal Servant", using its body, while still using your own abilities as a spellcaster. But you cant expend a spell slot higher than fourth tier, and you need to upcast all spells by one tier, casted this way. 

You can only have one "Loyal Servant" at a time, severing the previous bond, when you attempt to create a new connection.
