I was recently playing an RPG, and a discrepancy came up: What should it take to contain a Fire/Ice bird, or Phoenix?
A little background: A Phoenix has been defeated and fallen into a pile of ashes/dust, but has had its ashes gathered and put in a restraint facility.
What would this restraint facility be?
Limits:
- A fire bird needs access to oxygen to regenerate and survive - otherwise, it would disintegrate immediately - it needs to flame to survive.
- An ice bird needs water to reform at all.
- A fire bird is not solid in form - it is made of flame. An ice bird is made of ice, hence solid.
- The ashes need not be in one pile to reform, but separating them will make it more difficult (Less for the reincarnation to regenerate from).
- It can regenerate from any one if the piles of ash, however.
- It must prevent it from reforming, and escaping. This means that you should always have a pile of ash or a Phoenix who can't get out.
- The restraint system cannot use gravity only to contain it. That doesn't stop/hamper it from reforming.
Apart from this, anything will fly with the DM (No pun intended). Bonus points if you can figure out how to create a generator from a phoenix that escapes the mechanism.
