Here will be our OOC Thread.
Yes, you can take an existing hearthstone write up and convert it to a Elemental Core.
A five dot familiar is pretty powerful, so I'll have to come up with some stats on it. And I am not familiar with a siege devastator. Obviously it is some kind of Essence weapon, but what are the stats of that one? Is it like the Glorious Solar Cannon?I'd like my five dot familiar to be a minor Destroyer spirit - an orichalccum motorcycle that can adhere to surfaces to drive up walls/along ceilings with an integrated spinal mounted siege devastator. It can collapse into just the siege devastator, a smaller essence cannon, an essence pistol, or a decorative earring. That way Incandescent Ray of Judgement can be barrelling along down a shaft on her motorcycle, deploy her wings to take flight, have the motorcycle fold up into a siege devastator, catch the weapon, and rain the Great maker's displeasure down on whatever's unfortunate enough to be around her, all without missing a beat. Since her motorcycle/weapon is an Essence 3 Machine Spirit it has its own mote pool and Charms (probably the bit about wall riding and collapsing into a tiny concealable shape, and we can worry about the others if they ever come up).
