Wire's Forge of Goodtential

Forge of Goodtential changes how the Forge of Potential calculates refinement risk.

The selected idol controls the power and risk of the attempt. An optional trophy can make a safe attempt more reliable. Lower-tier idols can also be used as a high-risk, high-reward option.

Quality and base success chance

Let:

• Qmax = the item's normal maximum quality.
• Q = the item's current quality.
• R = extra refinement already gained above the normal cap.

R = max(0, Q - Qmax)

The base success chance is:

Success = max(65%, 90% - 5% × R)

This gives:

Extra refinement R	Base success
0	90%
1	85%
2	80%
3	75%
4	70%
5+	65%

The displayed success percentage includes both normal +1 results and jackpot results.

Minimum safe idol

Every item has a minimum safe idol tier for its next refinement.

For an item with a normal maximum quality of 4:

Target quality	Minimum safe idol
Q5-Q7	Item's native idol tier
Q8-Q10	+1 idol tier
Q11-Q13	+2 idol tiers
Q14-Q16	+3 idol tiers
Q17-Q19	+4 idol tiers
Q20-Q22	+5 idol tiers

The progression continues until Bloodgold, which remains the highest required tier.

The default selected idol is always the lowest safe idol available for the item.

Safe idols

A safe idol is an idol at or above the minimum safe tier.

Using the minimum safe idol keeps the base success/failure distribution for that refinement level.

Using a stronger idol reduces bad outcomes.

For each idol tier above the minimum:

Ordinary failure multiplier = 0.72 ^ tiers_above
Reset multiplier            = 0.45 ^ tiers_above

The probability removed from those outcomes is added to success.

Failure types

Before the item has gained 2 extra quality levels, a failed roll is an ignore result: the idol is consumed and the item is unchanged.

At 2 or more extra quality levels, ordinary failure can lower the item's quality.

At 4 or more extra quality levels, a failure can remove multiple gained quality levels.

At 5 or more extra quality levels, a reset outcome becomes possible. Reset returns the item to its normal maximum quality instead of destroying it.

Trophy offerings

One trophy may be offered on a safe attempt.

Trophies reduce bad outcomes. Their effect depends on the strength of the defeated creature relative to the item being refined.

Each trophy has an internal prestige score. The item also has a reference prestige based on its progression.

For an item above its normal quality cap:

Item tier reference = native tier + (extra quality / 3)

Tier prestige anchors are:

Tier	Prestige
Wooden	6
Bronze	20
Iron	30
Silver	40
Black Metal	48
Black Marble	58
Flametal	68
Bloodgold	82

Let:

delta = trophy prestige - item prestige
M = clamp(e ^ (-0.11 × (delta + 9)), 0.03, 0.98)

Then:

Ordinary failure ×= M
Reset chance     ×= M ^ 1.8

A stronger trophy therefore has a much larger effect on a weaker item, while an outdated trophy has very little effect on a highly refined item.

Trophies cannot be used with an under-tier idol.

Under-tier idols

An idol below the minimum safe tier can still be used.

This changes the attempt into a destruction gamble.

Let:

D = minimum safe idol tier - selected idol tier

For every tier below the minimum:

Success chance   -= 2.5 percentage points
Jackpot trigger  += 10 percentage points

All non-success probability becomes destruction.

Example:

If the minimum safe idol would give:

85% success
10% ignore
5% reset

then one tier below becomes:

82.5% success
17.5% destruction
30% jackpot trigger on a successful attempt

Two tiers below becomes:

80% success
20% destruction
40% jackpot trigger on a successful attempt

A destruction result destroys the item and returns its recoverable crafting materials.

Because destruction can return materials, under-tier attempts require enough free inventory space for those returned items.

Selecting an under-tier idol clears the selected trophy and disables trophy cycling.

Jackpot refinement

Jackpot chance is hidden in the Forge UI.

On a safe attempt, a successful refinement has a 20% chance to become a jackpot.

For each idol tier below the minimum safe tier, the jackpot trigger increases by 10 percentage points.

When a jackpot triggers, the item gains at least +2 quality instead of +1.

After that, each additional quality level has a 20% continuation chance, up to +5 total quality.

If J is the jackpot trigger chance, the quality gain on a successful attempt is:

+1 = 1 - J
+2 = J × 0.80
+3 = J × 0.16
+4 = J × 0.032
+5 = J × 0.008

For the normal 20% jackpot trigger:

+1 = 80%
+2 = 16%
+3 = 3.2%
+4 = 0.64%
+5 = 0.16%

Forge UI

The four Forge slots are:

[Idol] [CI] [Trophy] [CT]

• CI cycles through owned idols.
• CT cycles through owned trophies.
• Cycling is disabled while a refinement is in progress.
• CT is disabled while an under-tier idol is selected.
• If there is nothing to cycle through, the corresponding button is disabled.
• Idol names show the material on the top line and Battle or Protection below it.
• Trophy names omit the redundant word Trophy.
• The orange status line shows only non-zero outcomes.

Possible displayed outcomes are:

success
ignore
fail
reset
destruction

Example:

82.5% success   17.5% destruction

The jackpot chance is not displayed.
