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 depends on the level of the Gems being upgraded. By adding an Upgrade Booster item, the success rate increases by 100% points.

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%	10	1
2 → 3	65%	20	5
3 → 4	60%	40	10
4 → 5	55%	60	20
5 → 6	50%	80	30
6 → 7	45%	100	50
7 → 8	40%	200	100
8 → 9	35%	300	150
9 → 10	30%	400	200
