You split part of yourself off from your body and it takes new form. You gain the service of a Trobling, a part of yourself that you can shape as you wish. The Trobling's movement echoes your own; it cannot fly if you've no wings, it cannot swim if you give it no ability to. It can take the shape of most anything, as you can as a Hobtroblin, but will only have eyes, ears, or a mouth if you give it one. A Trobling may, for instance, take the form of a Rat, Cat, Frog, Hawk, Lizard, Octopus, Owl, Bat, Raven, Spider, Weasel, etc. Appearing in an unoccupied space within range, the Trobling has the statistics of the chosen form, though it is a Fey instead of a Beast. Your Trobling acts independently of you, but it obeys your commands.
Telepathic Connection. While your Trobling is within 100 feet of you, you can communicate with it telepathically. Additionally, as a Bonus Action, you can sense the world around the Trobling through whatever senses it has at its disposal until the start of your next turn.
Finally, when you cast a spell with a range of touch, your Trobling can deliver the touch. It must be within 100 feet of you, and it must take a Reaction to deliver the touch when you cast the spell.
Combat. The Trobling is an ally to you and your allies. It rolls its own Initiative and acts on its own turn. A Trobling can’t attack, but it can take other actions as normal.
Disappearance of the Trobling. When the Trobling drops to 0 Hit Points, it disappears. If possible, you may reabsorb the Trobling into your body so long as it is within reach when it drops. If you are unable to access the Trobling, that part of yourself is lost forever. As a Magic action, you can reabsorb the Trobling into your body. As a Magic action while it is temporarily dismissed, you can cause it to reappear in an unoccupied space within 5 feet of you. Whenever the Trobling drops to 0 Hit Points, it leaves behind in its space anything it was wearing or carrying.
Number of Troblings. You may have any number of Troblings you choose that your body is capable of creating. The number is limited by the size of your heart and your brain; which must always be contained within a single form capable of carrying them.
