This article is about the Golbin Raid minigame. For a guide to progressing through the minigame, see
Golbin Raid/Guide.
The Golbin Raid is the first permanent minigame added to Melvor Idle. It is intended to be a fun distraction for those who want to take a break from the grind, offering unique rewards exclusive to the minigame.
The minigame is specifically designed to be fair for everyone, at any level of the game, as such there is no advantage to having high level stats or items.
How to Play
 Defeat infinite waves of Golbins, progressing in difficulty and Combat Level each wave.
 You start at Level 1 Combat Skill Levels ( Level 10) which increases by 1 at the end of each wave.
 Start with only a Bronze Scimitar (or an Adamant Scimitar if Jerry the Giraffe has been unlocked), 200 Bronze Arrows, 500 Air Rune, 500 Water Rune, 500 Earth Rune, 500 Fire Rune, 500 Mind Rune, and 10 Shrimp.
 At the end of each wave you can select the desired item you wish to equip, chosen at random.
 Get as far as you can with the best build possible.
 Visit the Raid Shop to purchase upgrades that will assist in the Raid.
 Running or dying in the Raid will reward you with Raid Coins based on what Wave you got up to. You cannot earn Raid Coins prior to Wave 4.
 Everyone attacks twice as fast in the Raid.
Important Information
 All Skills, including Combat, are placed into "Offline Mode" during a Raid. Once a Raid is finished, you will be rewarded with progress for the Skill.
 Running out of Runes or Ammo during Combat or selecting a weapon that isn't compatible with your existing Ammo will replace your weapon with a Bronze Scimitar.
 Auto Eat  Tier II is active throughout the Raid.
 There are no Summoning, Potions, or passive Pet Bonuses.
 No Combat XP is gained during the Raid.
 You are limited to only 1 Equipment Set, and 1 Equipped Food. Choose wisely.
 The Weapons and Gear you can select are gated behind Wave requirements. Check the selections screen for info.
 All Runes acquired during the Raid are stored. Check the My Runes page in Combat to see what you have.
 All Magic Spells are unlocked from the start.
 Combination Runes, Nature Runes, and Spirit Runes cannot be obtained while raiding. Players should ensure that the "Use Combination Runes" option is disabled when using Magic, otherwise spell casts will fail and the player will be reverted back to their starter weapon.
 Combat Triangle Modifiers for Standard & Hardcore characters still apply here (Including no Hitpoints regeneration for Hardcore).
 This is a safe minigame. Hardcore Characters are safe if you die.
 All Golbins killed during the raid count towards unlocking the Golden Golbin pet.

Shop
The Golbin Raid minigame has its own shop, from which the player can purchase various upgrades in exchange for Raid Coins. All purchases made within this shop will only impact the minigame, and will have no effect on other areas of the game.
Raid Coins
The number of Raid Coins earned increases with the number of cleared waves. The amount of coins earned for a raid is given by:
[math]\displaystyle{ \text{Raid Coins} =
\begin{cases}
\text{difficulty} \times 3.6 \times \text{wave} \times \left \lfloor 2 + \frac{\text{wave}}{4} \right \rfloor \times \left \lfloor 1 + \frac{\text{wave}}{15} \right \rfloor & \text{if wave} \ge 3 \\
0 & \text{if wave} \le 2
\end{cases}
}[/math]
Where:
 [math]\displaystyle{ \left \lfloor x \right \rfloor }[/math] is the floor function
 [math]\displaystyle{ \text{difficulty} }[/math] is:
 .75 on Easy
 1 on Normal
 1.5 on Hard
 [math]\displaystyle{ \text{wave} }[/math] is the number of waves cleared

The cost of skipping waves also increases with the number of waves, where the cost of skipping wave number [math]\displaystyle{ \text{wave} }[/math] is given by:
[math]\displaystyle{ \text{Skip Cost} = \left \lfloor 100 \times \left ( \text{wave} + 1 \right ) \times \left ( 1  \text{Skip Cost Reduction} \right ) \right \rfloor }[/math]
where: [math]\displaystyle{ \left \lfloor x \right \rfloor }[/math] is the floor function.
Where [math]\displaystyle{ \text{Skip Cost Reduction} }[/math] is 0.01 multiplied by the number of times the "Reduce Wave Skip Cost" upgrade has been purchased, up to a maximum of 0.5.
Ammo
If Ammo is chosen during the selection phase, two random options will be offered alongside an option to increase your existing ammo. The quantity of Ammo offered increases with the number of cleared waves, can be increased by purchasing the Ammo Gatherer upgrade within the raid shop, and is a random amount between [math]\displaystyle{ 1 }[/math] and the maximum quantity:
[math]\displaystyle{ \text{Ammo Max} = 25 \times \text{wave} \times \left ( 1 + \text{Raid Shop Multiplier} \right ) }[/math]
Where [math]\displaystyle{ \text{Raid Shop Multiplier} }[/math] has an initial value of 0, increasing by 0.05 for each time the Ammo Gatherer upgrade has been purchased.
Runes
If Runes is chosen during the selection phase, two random options will be offered, and a option to increase your existing ammo. The quantity of Runes offered increases with the number of cleared waves, can be increased by purchasing the Rune Pouch upgrade within the raid shop, and is a random amount between [math]\displaystyle{ 10 }[/math] and the maximum quantity:
[math]\displaystyle{ \text{Runes Max} = 25 \times \text{wave} \times \left ( 1 + \text{Raid Shop Multiplier} \right ) + 9 }[/math]
Where [math]\displaystyle{ \text{Raid Shop Multiplier} }[/math] has an initial value of 0, increasing by 0.05 for each time the Rune Pouch upgrade has been purchased.
Food
If Food is chosen during the selection phase, three random options will be offered. The quantity of Food offered increases with the number of cleared waves, can be increased by purchasing the Food Bonus upgrade within the raid shop, and is a random amount between [math]\displaystyle{ \text{wave} + \text{Raid Shop Bonus} }[/math] and the maximum quantity:
[math]\displaystyle{ \text{Food Max} = 12 \times \text{wave} + \text{Raid Shop Bonus}  1 }[/math]
Where [math]\displaystyle{ \text{Raid Shop Bonus} }[/math] has an initial value of 0, increasing by 5 for each time the Food Bonus upgrade has been purchased.
