You gain Heroic Inspiration whenever you finish a Long Rest.

You gain proficiency in one skill of your choice.

You gain an Origin feat of your choice.

Unbalanced Mind: The minds of daelkyr half-bloods are in constant self revolt, reflecting their daelkyr "parents" mixed with the more standard mindset of their biological mothers. Any creature that attempts to read the thoughts of a daelkyr half-blood, or otherwise study their mind, must make a Will save (DC 10 + 1/2 half-blood's level + Cha modifier) or be dazed for 1 round.
You have advantage on saving throws to resist becoming frightened or charmed.

Symbiont Dependency: Daelkyr half-bloods' facility with symbiont usage comes at a price. Without daily contact with at least one symbiont, a daelkyr half-blood begins to die. If a daelkyr half-blood has no contact with a symbiont for 24 hours, they take 1 point of Constitution damage. They take this damage every 24 hours until contact is restored, and Constitution damage sustained in this fashion cannot be restored by any means as long as the daelkyr half-blood remains separated from symbionts.

Symbionts depicted left to right: 
(Stormstalk, Winter Cyst, Crawling Gauntlet, Shadow Sibling, Throwing Scarab, Spellwurm, Breed Leech)


Personal Symbiont: All half-bloods begin play with one personal symbiont that they can pick from the following list: breed leech, crawling gauntlet, or throwing scarab. If a personal symbiont is lost, a daelkyr half-blood can grow a replacement from their own flesh over a period of 2d4 days. A daelkyr half-blood can't grow or regrow symbionts that they have gained in any other manner, nor can a daelkyr half-blood grow a replacement for a symbiont if the original symbiont yet lives.

As a daelkyr half-blood advances in level, they can grow a new personal symbiont as indicated on the table below. Any new personal symbiont grown replaces the old symbiont. A daelkyr half-blood can choose additional symbionts from the list provided above, as well as from new choices as they become available, as indicated on the table.
