MapleStory/Spell Trace and Star Force

This page serves to cover the basic equipment upgrade systems: Spell Trace and Star Force.

Spell Trace
Spell Trace is used to consume upgrade slots to improve your equipment power. There are 3 possible upgrade choice (4 for weapons) with varying success rates and stat enhancement. Enhanced stat values and Spell Trace Cost depends on equipment level and type.

Limitations
Spell Trace Enhancement is only for non-reboot worlds. Reboot world players however can sell Spell Trace to NPC for 5,000 meso each.

Options
There are 3 tiers of enhancement depending on equipment level.

On the 4th success, if you used Spell Traces for enhancement you will receive +1 Weapon Attack (Magic Attack for Magician equips, both for universal equips)

Special Scrolls
There are 2 Special scrolls: Clean Slate Scroll 5% and Innocence Scroll 30%. These scrolls success rates are not affected by any success rate increasing effects except Spell Trace Fever Time. Click on the Scroll button at top left of the enhancement UI to access these sctoll options if your equipment is fully enhanced and is eligible for Star Force Enhancement.
 * Clean Slate Scroll 5%: Restores 1 failed upgrade slot. Cost 2000 Spell Traces.
 * Innocence Scroll 30%: Reverts the equipment back to its original stats (except potential, additional potential and additonal options). Cost 5000 Spell Traces.

Spell Trace Fever Time
During Spell Trace Fever Time, success rates of all Spell Traces are increased! Note that this increase effect stacks with other success rate increasing effects except Clean Slate Scroll and Innocence Scroll.

Star Force Enhancement
Star Force Enhancement is the additional enhancement after the equipment's upgrade slots are fully used up. Infuse stars into your equipment for additional stats! This system costs mesos to use.

Normal Equip
Based on the server, different rates are applied. There are 4 possible outcomes but only 3 possible outcome at any point: Success (+1 Star), Fail (Maintain), Fail (-1 Star), Destroy (Leaves an equipment trace)

Success Rates
Maintain and decrease percentages are based on Overall % and not a % of non-success rate. Brackets show the % of non-success rates.
 * GMS, EMS, KMS (Max 15 Stars for GMS and EMS)


 * MapleSEA

Meso Cost
Meso cost is rounded off to the nearest hundreds. For Current Stars 12 to 16, you can pay double the cost to remove the chance of destruction.
 * GMS, EMS, KMS

Meso Cost at a certain star = $$1000+(EquipLevel^3)\times (CurrentStar+1)/25 $$ For Current Stars 12 to 16, you can pay double the cost to remove the chance of destruction.
 * MapleSEA

Stats Boost
This section shows the stats increase by star force enhancement, which is why it is strongly encouraged since it is fairly cheap.

If the equipment can be worn by all jobs, all 4 stats will be boosted. Total stats exclude additional options. % based increases may not be accurate as they are rounded up each time it is formulated for each star.

Superior Items
Similar to Normal equips but the rates are different from Normal equips. However the stat gained is tremendous.

Success Rates
Maintain and decrease percentages are based on Overall % and not a % of non-success rate. Brackets show the % of non-success rates.

Meso Cost
Meso Cost for all stars for the same equipment is the same.

Meso Cost = $$EquipLevel^{3.56}$$, rounded off to nearest hundreds.

Star Force Conversion
For Demon Avengers, since Star Force enhancement does not give HP that is actually meant for damage enhancement, additional HP is compensated for Demon Avengers only. Based on current Star Force, HP given is based on tiers. If you changed tiers, the HP difference for earlier stars will be compensated. Note that Stars from Superior equipments are treated the same as Normal equip Stars, similarly for 16+ Stars and the lower stars. Overall stars are double counted.
