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. Generally, higher equipment level and lower success rates will cost more spell traces but provide higher stat boosts. During certain Sundays, success rates for spell traces may be increased (known as Spell Trace Fever Time) or spell trace consumption may be lowered.

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.

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

Armor (except gloves)

 * Stat Choices (Primary Stat)

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)
 * Stat Values

Gloves

Special Scrolls
There are 3 Special scrolls: Clean Slate Scroll 5%, Innocence Scroll 30% and Ark 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 scroll options if your equipment is fully enhanced and is eligible for Star Force Enhancement.
 * Clean Slate Scroll 5%: Restores 1 failed upgrade slot. Cost 2,000 Spell Traces.
 * Innocence Scroll 30%: Reverts the equipment back to its original stats (except potential, bonus potential and bonus stats). Cost 5,000 Spell Traces.
 * Ark Innocence Scroll 30%: Works exactly like Innocence Scroll but Star Force (and its relevant stats) will be kept. Percentage based stat increases will also be adjusted spontaneously. Cost 10,000 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.

For Clean Slate Scroll, Innocence Scroll and Ark Innocence Scroll, other success rates increasing effects are not applied, only Spell Trace Fever Time can increase their success rate.

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 stat bonuses! 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★), Fail (Maintain), Fail (-1★), Destroy (Leaves an equipment trace which will be rolled back to 12★)

During 1+1 star force events, for equipments that are 10 stars or below, succeeding in star force enhancement will let the equipment gain 2 stars instead of 1 star with the stats added accordingly.

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

During certain events, some of the attempts may be 100% success rate during the event period (typically for 5★ → 6★, 10★ → 11★ and 15★ → 16★).

Meso Cost
Meso cost is rounded off to the nearest hundreds. Equip Level is rounded down to the nearest 10 levels.

For all servers, if you are an MVP or Internet Cafe/Premium Service Coupon player you can obtain further discounts (only applied to base price before destruction removal costs, up to 16★ → 17★). During certain events you can obtain a 30% discount (for all regular equips regardless of current stars, exclude destruction removal costs), multiplied with above discounts
 * MVP
 * Silver: 3% discount
 * Gold: 5% discount
 * Diamond: 10% discount
 * Premium Service (added with MVP): 5%

For 12★ → 13★ to 16★ → 17★, you can pay double the cost to remove the chance of destruction.
 * KMS, MapleSEA


 * GMS

For 12★ → 13★ to 16★ → 17★, you can pay double the cost to remove the chance of destruction.

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 bonus stats. % based increases may not be accurate as they are rounded up each time it is formulated for each star. The scaled stats are updated spontaneously when there is a change in stats due to scrolls, so the enhancement sequence will not affect the end state of an equipment. Bonus Stats have no effect on scaled stats. {| !Attempt!!Stats gained for success!!Additional Stat Bonuses on certain equips

Armors Total Stats
For convenience, the total stats gained from enhancement will be listed below. Table excludes non-damage stats.
 * Stats refer to Primary and Secondary stats. (All stats for certain equips)
 * ATT refers to both Weapon and Magic ATT, excluding ATT from gloves in the first 15 stars (only the matching ATT is increased for this)

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

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

Superior Shielding Ward cannot be used to remove destruction chance im star force for 5★ → 6★ and 6★ → 7★. However, it can still protect destruction from equip enhancement scrolls.

Meso Cost
Meso Cost for all stars for the same equipment is the same. Equip Level is rounded down to the nearest 10 levels.

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

Total Stats
For convenience, the total stats gained from enhancement will be listed below. Table excludes non-damage stats.
 * ATT refers to both Weapon and Magic ATT.

Star Catcher
Before each attempt, you will play a Star Catcher minigame where a star will move from left to right, then right to left, repeating its cycle. Press the "Stop" button or press "Spacebar" to stop the star from moving. If it lands on the yellow region marked out in the Star movement path, Success rate +4.5% multiplied. Maintain/Decrease and Destroy rates will be redistributed at the same bracketed rates.


 * Note:
 * If you enhance 20 times successively within a short period (10 minute window based on server time, measured from 12am) star movement speed increases and the yellow region area decreases (difficulty increases by 1 tier)
 * From the top of the hour, every 10 minutes, the difficulty will decrease by 1 tier.
 * There are 4 tiers of difficulty. Minimum difficulty is Tier 1 and maximum difficulty is Tier 4.

You can cancel this minigame by ticking "Cancel Star Catcher" but the success rate boost will not be applied but you get to enhance way faster (does not mean you will save time in the long run though, since you are slightly more likely to fail enhancements and decrease stars)

Chance Time
If your equipment decrease stars twice in a row, you enter this special state called Chance Time. In this state, success rate 100% and it lasts for 1 enhancement. (Effect will be gone if you either utilised it, did not enhance within 5 minutes, or enhanced another equipment)


 * Note:
 * Chance Time only applies to the equipment that triggers it (not transferrable to other equips)
 * If you are allowed to pay double mesos to remove destroy chance, for chance time you don't need to pay double mesos since there is no destroy chance if it is 100% success rate.
 * Star Catcher minigame will not appear during Chance Time since the success rate is already 100%.

Equipment Traces
When you destroy your equipment due to failure in star force enhancements, the equipment will leave a trace. You can use the "Equipment Transfer" in the Enhancement UI beside "Star Force Enhancement" (not to be confused with Transfer/Todd's Hammer) to transfer all stats on the trace into a new piece of the same equipment. All other non-star force stats are retained and will be transferred to the new copy of the same equipment: weapon soul, potential, additional potentials, scrolled stats, bonus stats and tradability (Untradeable/Tradable till worn/Can be traded once/Fully tradable)
 * For Normal equips, 12 Stars (as well as its relevant stats) are retained.
 * For Superior equips, stars as well as its relevant stats are not retained.

Equipment traces are only given for destroying due to star force enhancement attempts only. Destruction due to other means will not give any traces (so your equipment will be lost forever).
 * Warning

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.
