Route modifiers

Affixes & Biomes

Shard level controls available modifier tiers, while rarity determines how many non-conflicting modifiers the route receives.

Affix generation

Shard level is clamped from 0 through 99 and unlocks one additional maximum modifier tier every ten levels.

Category coverage: Affixes draw in order from Generation, Spawning, Monster Stats, and Special until the rarity's affix count is reached. The highest rarity receives one additional non-conflicting affix.
Tier roll: Only tiers unlocked by shard level can roll. Tier t receives weight t², favoring higher available tiers without removing lower ones.
Value roll: Each affix rolls inside its tier range. Tiers 2–9 interpolate between the tier 1 and tier 10 endpoints.
Mutual exclusions: Opposing size and route-shape modifiers cannot appear together, and no shard can roll duplicate affixes.
Save capacity: Up to 512 shards are accepted by save normalization as a safety limit.
