A kodai (+) is a combat potion that boosts the player's Magic level by 6 + 16% of their base level. It can be made with 70 Herblore by using a golpar with a water-filled gourd vial while having endarkened juice in the inventory. Making this potion gives 13 Herblore experience.
This potion is the strong variant of the kodai potions, and cannot be taken out of the Chambers of Xeric. As a consequence, it does not help in casting enchantment spells.
