Instability
The instability score
Every age has an instability score, built from:
- its symbols
- the book
- how many valuable blocks it generates beyond a normal age's share: coal, copper, lapis, iron, emerald, redstone, gold, diamond, crystal, glowstone and quartz
What happens in an unstable age
Unstable ages suffer effects dealt from decks of cards:
- potion effects on creatures
- stronger mobs
- burning
- crumbling
- explosions
- lightning
- meteors
- spreading decay blocks: Black, Red, Blue, Purple and White Decay
Picture to add: decay blocks spreading through an unstable age
For server owners
Instability can be turned off, scaled, and have specific effects banned. See Configuration. Operators can also check and change an age's instability with commands.
