[Monster] It is coming, and it is bringing the plane with it.

Awesome Idea!

Just throwing some ideas out there off the top of my head

• Given them an Aura that gives the traits of the plane they are "bringing with them".
• Determine the Strength and Size of the Aura based on an Elemental like classification scale or perhaps a dragong age category scale.
• them get stronger based on the time they spend in a plane.
• Have creatures that stay in the bubble too long start to have their Type or sub-type changed while they are inside the aura.
• Have creatures killed by this thing rise as elementals if they stay dead too long inside the aura. Perhaps give a saving throw but make it much harder for creatures that aren't native to the plane combat is taking place on: sort of representing their link to the plane that's trying to resist becoming part of something else.
