About | Raising Weapon Skills
Raising weapon skill levels requires sacrificing other weapons with skills or Fury Pebbles/Fury Stones as upgrade fodder. When upgrading a weapon with another weapon with a skill and/or Fury items, the upgrade summary will state "Skill Level Rise Rate: X%." This is the chance your weapon will gain a skill level if you perform this upgrade. Depending on the weapon rarity and current skill level, different amounts of upgrade fodder is needed to reach a 100% chance.
Weapons with two skills with skill levels will have both skills increased at once at the same cost, even if one of the skills is inactive until a certain level.
To make calculations easier, the Granblue Fantasy community has assigned point values to common upgrade fodder and created a table of skill levels with the number of points needed to reach a 100% chance of upgrading a weapon's skill. Note that 100% is the highest rate you can get; using more points than necessary will not allow you to get more than 1 skill up per upgrade.
Fodder (skill level 1) |
Points |
---|---|
1 | |
4 | |
40 | |
Fury Pebble | 2 |
Fury Stone | 4.8+ |
A fodder weapon or Fury Pebble/Stone is worth as many points as its base form times its skill level, e.g. Yggdrasil Bark is normally worth 4 points, but an Yggdrasil Bark with skill level 3 (sk3) is worth 12 points. Uncapping or weapon level do not factor in at all and should be avoided for fodder.
For scenarios requiring 56-80 points (SSR sk7-10), it is more efficient to skill up a fodder SSR rather than to use base materials. A SSR sk2 is worth 80 points, but it only requires 1 SSR sk1 plus 2 SRs sk1 to create it. That means your base materials are worth only 48 points, but you are creating skill fodder worth 80 points.
In addition, since you can only select up to 20 weapons for a single skill-up attempt, its impossible to skill up with a 100% chance with SR fodder sk1 alone past 80 pointsor 96 points using Fury Stones, so skilling up fodder weapons is pretty much required at higher skill levels, especially for Bahamut & Seraphic weapons as outlined below.
To make a SSR sk3, you need a SSR sk1, 2 SR sk1 for the first skill up, and 4 SR sk1 for the second skill up. So you are putting in 64 points to make fodder worth 120 points. This does mean that going from SSR sk11->12, it's more efficient to skill up using 1 SSR sk2 and (2 SR sk1 or 1 SR sk2), but for the rest of the skill levels a SSR sk3 will be the most efficient course.
Those tricks do not work on SSR weapons that only have a weapon skill without skill levels, such as Cosmos weapons and some of the Rise of the Beasts weapons.

- Note: The + indicates that attempting to level skill with the exact number of points may result in a 99% success rate. This can result in failure, so it is recommended to just find 1 more R weapon to reach 100%.
- Example using this chart: To level up a SSR sk4, you need to feed it 32 points worth of fodder, which could be 8 SRs, or 6 SRs + 8 Rs, or 4 SRs + 16 Rs.
Bahamut, Ultima, Seraphic, Dark Opus & 5★ Weapons[edit]
5★ Weapons from sk15, Bahamut Weapons, Ultima Weapons, Dark Opus Weapons and Seraphic Weapons require 40 points, or 1 , per skill level. So, knowing that it only requires 8 points per skill level to skill up a standard , you can imagine how to make the skill up process less painful. However, depending on how many fodder weapons you have available, certain combinations can be even more efficient than simply skilling up one SSR.

So what we discover here is that, even though
sk5 is still very efficient (generates 200 points but only requires 120 to create), it is actually more efficient to use multiple SSRs to add up to a skill of 5 instead. However, this method relies on having access to many extra SSRs, so this information may or may not be useful to every player.Summary and Tips[edit]
If you are having issues following the above explanation, you can remain largely efficient while leveling these types of weapons if you use the following general rules:
- Always use that are sk 1 or sk2 to level up an .
- Using multiple sk2 Bahamut Weapons is most efficient, but it remains efficient to use up to Sk5 if you need to for later levels if you don't have enough weapons (never upgrade fodder to sk8 or above). to level
- Each level up on Bahamut Weapons requires as many total skill levels as its own level to rank up. For example, sk5 Bahamut Weapons take 5 skill levels to them to level to sk6. This means upgrading it would take
- one sk5
- or one sk3 and one sk2
- or five sk1
- or some other combination that adds up to 5 total.
- If any skill up is 99% chance, add weapons to take it 100%. 4 weapons are equivalent to 1 weapon. But in most situations due to space concerns, it is best to use 4 weapons to level up an weapon to sk2 and use that.
- weapons without a skill do not add any points.
