Crystal Tiers

A crystal's tier is determined by the base + catalyst pair used in the Crystal Former, and sets the crystal's roll chance in the Resonator.

Tier	Base	Catalyst	Roll chance	Color
1	Sand	Glass	4%	#C6E2E9
2	Tinted Glass	Amethyst Shard	8%	#B57EDC
3	Tinted Glass	Prismarine Crystals	12%	#5AC8B8
4	Tinted Glass	Echo Shard	16%	#2E9AA6
5	Tinted Glass	Shulker Shell	20%	#A45FC0

Higher tiers cost rarer catalysts but roll noticeably more often — tier 5 rolls 5× as often as tier 1.

info

Roll chance here is the base per-cycle chance before the Resonator's rain/mob penalties are applied.
