Gems

Gems are items that can be mounted in a Vehicle’s Gem Socket to boost its Stats.

Typically, you can mount up to four Gems on a Vehicle. Each Vehicle has Gem Sockets of different colors. If you acquire a Plus-Marked Vehicle through Evolution, you can mount an additional Gem. For more information about the Plus Mark, please visit the [Evolution page].

There are eight types of Gems, categorized into four colors. You can only place a Gem in a Socket of the corresponding color.

Name	Color	Effect When Mounted
Speed(+)	Red	The Vehicle’s Speed is increased by N.
Speed(%)	Red	The Vehicle’s Speed is increased by N% of its Base Speed.
Luck(+)	Green	The Vehicle’s Luck is increased by N.
Luck(%)	Green	The Vehicle’s Luck is increased by N% of its Base Luck.
Yellow(+)	Yellow	The Vehicle’s Energy is increased by N.
Yellow(%)	Yellow	The Vehicle’s Energy is increased by N% of its Base Energy.
Blue(+)	Blue	The Vehicle’s Durability is increased by N.
Blue(%)	Blue	The Vehicle’s Durability is increased by N% of its Base Durability.

1) (+)type Gems

Mounting a (+)type Gem increases the corresponding Stat of the Vehicle by a set value. As these Gems consistently increase the same number, their effects remain constant regardless of the Vehicle’s original quality.

Gem Level	Value (N)
1	8
2	16
3	24
4	32
5	40
6	48
7	60
8	72
9	84
10	96

• Ex) If you mount a level 1 Speed (+) Gem on a Vehicle, its Speed increases by 8.

2) (%)type Gems

Mounting a (%)type Gem increases the corresponding Bast Stat of the Vehicle by a fixed percentage. Note that the percentage increase does not consider the Stats enhanced by Stat Point distribution. As a result, Vehicles with higher Base Stats benefit more from (%)type Gems.

Gem Level	Value (N%)
1	30%
2	60%
3	90%
4	120%
5	150%
6	180%
7	220%
8	260%
9	300%
10	340%

• Ex) If you mount a level 1 Speed (%) Gem on a Vehicle with Base Speed 50, its Speed increases by 15 (which is 30% of 50).

3) Gem Upgrade (That part contains unfixed numbers. Success rate and Upgrade Booster is under reviewing until release date of Pre-OBT)

By combining three Gems of the same color, effect, and level, you can attempt to upgrade them. A successful Upgrade yield a Gem of the next level.

• Ex) if you upgrade three level 1 Speed (%) Gems and succeed, you obtain a level 2 Speed (%) Gem. If the Upgrade fails, the three Material Gems are lost.

The success rate varies depending on the level of the gem being upgraded. Adding a regular upgrade booster item increases the success rate by 20%, while adding a super upgrade booster item increases it by 50%. You cannot use both the regular and super booster items at the same time — only one can be used.

The table below provides the Upgrade success rates without a Booster and the required token costs.

Gem Level	Success Rate	XPER Cost	PER Cost
1 → 2	70%	80	8
2 → 3	65%	160	40
3 → 4	60%	320	80
4 → 5	55%	480	160
5 → 6	50%	640	240
6 → 7	45%	800	400
7 → 8	40%	1,600	800
8 → 9	35%	2,400	1,200
9 → 10	30%	3,200	1,600
