How Equipment Potential Works: From Rare to Legendary Lines

Two progression tracks — don’t mix them up

Gear in Endless Adventure Online grows along two independent axes: enhancement pushes +0 to +15 and raises base stats, while potential decides which bonus lines the piece carries — Total Damage %, Crit Rate, HP %, lifesteal on hit and more. The same +15 weapon plays completely differently depending on its lines.

There is only one rule to memorize: 1 line on rare, 2 on epic, 3 on legendary — common and uncommon gear gets none. Every line rolls a rank from S down to D, and higher ranks mean bigger numbers.

What each tier can roll

Read the legendary row again: S-rank only exists on legendaries, at about a 20% shot. Potential progression therefore always ends on legendary gear — a double-B epic is a perfectly respectable stepping stone.

Four tools, one pipeline

① Potential Stamp

Grants potential to gear with none; stamp tier = gear tier (rare / epic / legend = 1 / 2 / 3 lines).

② Identify Scroll

Reveals unidentified lines — the actual stats and each line’s rank.

③ Potential Cube

Re-rolls the whole set — new lines, new ranks. The core consumable for chasing a roll.

④ Blessing Cube

Locks one line you like and re-rolls only the rest.

The pipeline: Stamp to unlock potential → Identify to reveal lines → Cube to re-roll if unhappy → Blessing Cube to lock the keeper and re-roll the rest. The Blessing Cube is the single most important loss-control tool in the system — turning a three-line gamble into a lock-one-roll-two operation changes the math entirely.

When to keep, when to roll

• › Something beats nothing: Stamp your endgame candidates first and wear any usable B-rank roll — perfectionist re-rolling is a late-game hobby.
• › Weapons first: Offensive lines (Total Damage %, Boss Damage %, Defense Ignore %) live on weapons, so weapon rolls pay off far more than armor rolls.
• › Stop when an S appears: Only legendaries roll S-rank, at roughly a 20% shot. If a correct S-line shows up, lock it with a Blessing Cube and re-roll the rest — never gamble the whole set again.
• › Cubes are a war of attrition: Potential Cubes are the core chase consumable and they are not common — collect them steadily from dungeon dailies, the weekly gold merchant and kingdom token shops.

Where the materials come from (free-to-play friendly)

Identify scrolls and rare stamps drop mainly from dungeon boss chests; the gold merchant sells rare and epic stamps on a weekly gold-only limit; and the Merchant Kingdom token shops stock Potential Cubes. The diamond mall sells volume and convenience — not exclusive power — so free players grinding steadily can chase the same endgame rolls.
