Puppet companion wins.

Emrys will be picking up a Puppet conjuration companion. It will follow his instructions completely, and in most cases won’t have any ability to act independently without using Autopilot’s actions every round. Autopilot can summon it at will, unless it gets killed in which case it will reset after a long rest. What kind of puppet?

A giant spider. Human sized, fast, and able to generate webs. Not the most dangerous combatant, but it’s webs could potentially offer a lot of utility and it can climb sheer surfaces.

Shadow Boxer- Emrys’s shadow gets up off the floor and starts cracking skulls with its bare hands. It will primarily serve as a bodyguard, as it can’t stray more than 5 feet away from Emrys. This connection makes it much stronger than it would otherwise be.

The Mistress: a pastiche of the drow women that have dominated and abused Emrys for the last century. Skilled with a whip, she spreads the pain around and leaves bleeding welts on everyone around her. Emrys always wished he could turn the tables on them. The real ladies in his life would be fairly offended.

The Nightmare: A far less grounded manifestation of Emrys’s fears. A creature of silk and whips and shadows meant to draw its victims down into the Abyss. It’s power is boosted to make it extra skilled at choking the life out of Emrys sized enemies, but as a being of pure fear its power requires a certain level of buy in. It can’t harm you much if you can convince yourself it doesn’t exist with a will save.

Femrys: a hypothetical Emrys that was born a girl and is better at combat magic than him, like Mother always wanted. She’s only a summon, and thus might not actually be stronger than Emrys, but she’s got her own spell points and nothing to use them on except blasting her/Emrys’s enemies away.

Dierdre: Not a puppet, unlike the rest of the options. Contract with Dierdre as a familiar instead of a normal called creature. She will be drastically weaker than any of the puppets, but can operate independently. As a summoned (rather than called) creature, she can die as much as she wants without consequence to her real body. Her abilities and appearance will be somewhat altered by animating an artificial summoned body.
