A drop-rate simulator built on classic, pre-Renewal Aegis/Hercules mechanics: per-item base rate × server rate config, clamped to min/max. No level penalties — old-school RO.
Classic/pre-Renewal Ragnarok has no level-difference drop penalty — your base level and the monster's level never affect drop chance, only the base rate, server config, and boss/MVP status do.
100 = ×1.00 (rates as stored in the mob DB). 600 = six times higher. These mirror item_rate_* in Hercules' drops.conf.
Only used when "Boss-protocol monster" is checked above.
Min/max final rate, in 0.01% units (default 1–10000 = 0.01%–100%).
Mirrors the engine's rule for these buffs: the rate is only ever raised, and the raised value is capped at 9000 (90%) unless the item's rate was already higher than that on its own.
Base rate is in percent, using the same 0.01% granularity the mob DB uses (so 0.02 = 2 in 10,000). Illustrative examples are pre-filled — edit or replace them with your own mob's drop table.
Each drop slot is rolled independently on every kill — a single monster can drop several items at once, exactly as Aegis/Hercules resolve loot.
