Random Options & Graded Drop System

You'll see the A-grade glow before you pick it up. Two stacked loot systems — a D → A tier roll and a separate random-options roll — fire on every equipment drop. The chance both land high on the same piece is the entire endgame chase.

The Two Systems
  1. Random Options — random bonus stats rolled onto equipment
  2. Graded Drop System — tier ranking (D → C → B → A) that boosts the item's base performance

A single drop can be both high-grade and high-rolled. That's the endgame chase. That's also the item you'll dream about three weeks before you ever see one.

Graded Drop System

Equipment can drop pre-graded. Each grade increases the item's base bonuses on top of refinement and any random options. Higher grades are visually distinguishable in inventory and on the world drop sprite — you'll know an A-grade dropped before you even pick it up.

Where A-Grades Drop

Grade odds are weighted separately for normal monsters, mini-bosses, and MVPs — and the weighting depends on the item's level. Bosses and high-level gear are far more likely to roll B or A, while a basic drop will almost always land at D. The higher the threat you farm, the better your shot at a top-grade piece.

Random Options System

Independent of grade, equipment can roll random bonus options when it drops or is created. Each random option is a (ID, Value, Param) tuple — examples include race tolerance, elemental resistance, stat bonuses, ASPD, crit, and more.

  • Each piece of equipment can carry up to 5 random option slots
  • The pool of possible options depends on equipment type (weapons, armor, accessories)
  • Values within each option roll inside a defined range
  • A drop's tier decides how many options it gets — most drops roll a single option, while the rarest rolls fill all five slots
  • Combined with grade, this means no two drops are identical

How Grade and Random Options Stack

A typical comparison between a vanilla drop and the chase target:

AspectStandard DropEndgame Drop
GradeNoneA
Random Options0–1Multiple high-roll options
Refinement+0+9 to +10
Effective PowerBaseBase × Grade Bonus + Random Bonuses

All three systems — refinement, grade, and random options — are independent and stack with item base stats. A drop's grade is fixed when it drops; refinement and random options are what you shape afterward.

Rerolling Random Options

Not happy with the options a piece rolled? The Graded Reroller in Morroc can re-roll the random options on any equipped graded item — your grade, refine, and cards are never touched, only the options.

Three reroll modes are available, each priced in Zeny that scales with the item's grade and tier:

ModeWhat It DoesRelative Cost
Reroll Specific LinePick one option slot and re-roll it for a new option from the same poolCheapest
Reroll AllRe-roll every option on the item at onceMid
Reroll ValueKeep the same option, re-roll only its numberMost expensive
No Destruction Risk

Rerolling never destroys, downgrades, or unequips your item. The only thing at stake is the Zeny you spend — your grade and refine are always preserved. Higher grades and higher tiers simply cost more to reroll.

Why It Matters

  • Item identity — every drop has its own roll fingerprint; identical-looking gear plays differently
  • Endgame chase — A-grade with perfect random options is the true endgame target
  • Marketplace value — high-grade + high-roll items command real premiums in the Safe Marketplace
  • Build crafting — random options let players target specific resistances or burst damage profiles
  • Refine your roll — the Graded Reroller lets you chase the perfect option spread without risking the item itself
