Unit/Weapon

Unit Weapons, also referred in the user interface as "Exclusive", are an additional upgrade for units that can be unlocked after Player Level 68. 
Please note that similar to Unit Awakening, weapons are also released progressively into the game.
=How it works=
Weapons can be upgraded along two paths. Leveling up a weapon will increase the unit's base ATK and HP while also providing extra bonuses at weapon levels 20, 40, 60, 80 and 100 (specific for each unit). Ranking up a weapon will unlock extra abilities and/or stats. Higher rank weapons will also increase the base stats gained from weapon levels according to the table below.
Weapon Rank	Relative stat gain
Unawakened 	100%
0☆ Awakened	100%
1★ 	120%
2★ 	140%
3★ 	160%
4★ 	180%
5★ 	200%
6★ 	220%
=Leveling=
The maximum weapon level is 100(but can not exceed unit level) and costs increase as the weapon levels up.
To level up a weapon, Refinement Stones are required. This is a special currency that can be obtained through the Glory Arena and Glory Store.
To upgrade a weapon, it must be refined using stones, through a similar process as for leveling Hero Spells. The table below shows the number of steps and stones required for each level. For total Refinement Stones required, check the table at the bottom of the page. 
Critical gains are possible, doubling or tripling the number of steps gained with a single click.
Current Level	Steps Required	Cost/Step	Worst Case
0-3 	5 	1 	5
4-8 	5 	2 	10
9-13 	5 	3 	15
14-18 	6 	3 	18
19-23 	6 	4 	24
24-28 	7 	4 	28
29-33 	7 	5 	35
34-38 	8 	5 	40
39-44 	8 	6 	48
45-48 	10 	6 	60
49-53 	10 	8 	80
54-58 	12 	8 	96
59-63 	12 	10 	120
64-68 	15 	10 	150
69-78 	15 	12 	180
79-88 	15 	15 	225
89-100 	20 	15 	300
=Rank=
Just like units, besides level, the weapons follow a ranking system (also called "awakening" in-game) that enables special effects for the unit.
First the weapon must be awakened - point in which an exclusive ability becomes available to the unit (and it has technically 0 stars). After this, the weapon can be further upgraded 6 times up to 6* for another ability unlocked for the unit at each rank up.
To upgrade rank, weapon tokens are required.
* R and SR units use generic class-specific weapons, tokens for which can be obtained from the Glory Store and Glory Arena rewards section as well as various events. The table below shows each class with their associated weapon type:
Class 	Weapon
Defense	
Offense	
Caster 	
Charge 	
Ranged 	
* SR+ and SSR units have custom individual weapons which require tokens specific to that weapon. Some are available in Glory Store, others are only currently available for exchange during special paid events.
==Ranking Up==
Here are the number of weapon tokens required to unlock weapon ranks:
Rank 	Tokens Required	Cumulative
Awaken	100 	100
1★ 	50 	150
2★ 	90 	240
3★ 	130 	370
4★ 	170 	540
5★ 	210 	750
6★ 	250 	1000
==Void Mithril==
For SR+ weapons the conversion rate of Void Mithril to weapon tokens is 1:1 so you can follow the table above. For SSR weapons the conversion rate is 2:1, so to get the amount of Mithril you require for a specific rank either multiply by two or check the table below.
Void Mithril cost of SSR weapons
Rank 	Cost	Cumulative cost
Awaken	200 	200
1★ 	100 	300
2★ 	180 	480
3★ 	260 	740
4★ 	340 	1080
5★ 	420 	1500
6★ 	500 	2000
