Runecrafting

Runecrafting is one of the 12 Skills. It allows the player to fuse Runes onto their weapons and armor. Leveling Runecrafting is done by fusing runes, killing Runic Mobs, or by killing Bosses. Runes are only usable for cosmetic benefits and serve no purpose beyond that. Max Runecrafting level is 25.

It is one of three "cosmetic" skills, which have content locked to players without a Rank. Players with no ranks cannot increase past level 3 in the skill, and higher ranks apply a higher exp multiplier. As a "cosmetic" skill no important content or any stats require it to be leveled, and other than some small benefits it may provide (such as tabbed chests) it's purely decoration. The other cosmetic skills are Carpentry and Social.

Runes can be obtained by killing Runic Mobs. Some runes may only be obtainable via a specific set of conditions. Runic Mobs are a variant of regular mobs that rarely spawn. These mobs are at a higher level and have 4x more Health.

Each rune has an associated level. The runes can be fused- however, they cannot be activated until the player has their Runecrafting level equal to or greater than the level of the rune.

Runic Mobs
Runic Mobs are normal SkyBlock Mobs, but with 4x higher, and deal double damage. They have a purple name tag, and a much lower chance to spawn. When killed, they are guaranteed to drop a Rune.

It is possible to spot Runic Sea Creatures, Runic Brood Mother, and even Runic Headless Horseman. It is impossible however to spot a Runic Ender Dragon, Magma Cube Boss, Slayer Boss/Miniboss, Dungeon Boss or Dungeon Boss Minion. You can however get Runic variants of normal dungeon mobs, leading to insanely high amounts of on the Mob.

Fusing Runes
Runes can be fused on the Runic Pedestal, found behind the Blacksmith and owned by the NPC Dusk.

Fusing two runes together will have a chance of upgrading the rune to the next level, up to the maximum level of 3. Upon success or failure, the second rune is consumed. If this process does not succeed, the remaining rune will not gain the level. The chance of success can be seen in the Runic Pedestal while hovering over the apply trigger. Regardless of the outcome, this will also grant Runecrafting experience. More experience is awarded upon success.

Runes can be fused onto Swords, Bows, and Boots, depending on the type of rune. The player must have their Runecrafting level either equal to or greater than the level of the rune, or they won't be able to fuse it. This only applies to fuse runes to items, as runes above the player's Runecrafting level can still be combined together. Fusing runes onto items will also grant Runecrafting experience.

Slayer Runes
The drop rate of the 2 runes above with "Pray RNGesus" is approximately 0.32%(1/309).

Rates
Different rune rarities grant differing amounts of experience and have different success rates when fusing. F(n), the probability of successfully fusing on the nth attempt is represented as a function of P(n), the probability of merging on a given attempt. This distribution is binomial in nature.

$$ F(n) = P(n) * (1 - P(n))^{n-1}$$

C(n) the cost in runes on the nth attempt is

$$C(n) = 1 + n$$

Therefore, we can represent E(n), the expected number of runes during fusing as E(n) = ∑ F(n) * C(n)

$$E(n) = \sum P(n) * (1-P(n))^{n-1} * (1+n)$$ In order to calculate the expected runes to acquire

$$T_3$$ , we can represent the cost C(n) in terms of the cost of T2, or

$$C_3(n) = E(n) + E(n)*n$$

Therefore, the cost of T3 rune is

$$E_3(n) = \sum P(n) * (1-P(n))^{n-1} * (1+n) + n * \sum P(n) * (1-P(n))^{n-1} * (1+n)$$ $$= E(n) ^ 2$$ Alternatively, where

$$L$$ is the level of the rune desired:

$$ E_L(n) = (P(n)^{-1} + 1)^{L - 1} $$

Trivia



 * This skill was supposed to be released July 16, 2019, but was delayed to August 2, 2019, due to the need for more testing.
 * Slayer Bosses, Slayer Mini-Bosses, Ender Dragons and the Magma Cube Boss cannot appear as a Runic Mob. The only exceptions are Brood Mother and Headless Horseman.
 * The rarest Runic Mob is the Yeti, which when it appears, has.
 * The Headless Horseman Boss can also be Runic, giving it . With a base health of, it should have.
 * The glitched runes appeared from the original hour of the Runecrafting release date, they are most likely made unusable since every enemy dropped a blood rune.
 * The Tidal Rune is the only Rune that is in bold font.
 * The Jerry Rune is the only Rune that is only available in the 3rd tier.
 * The Enchant Rune is the first Rune that can be applied to Chestplates.
