  • If you have a hero with short cooldowns on your abilities, consider this item; casting your spells more often in a single fight is a major boon, and the increased casting range allows you to do so without having to stay in the middle of the fight for an extended duration.


  • Octarine Core's name is an homage to the comic fantasy book series Discworld, paying tribute to the writer Terry Pratchett who died about a month prior to the item's release.
    • In the series, Octarine is a fictional color which is described as "resembling a flourescent greenish-yellow purple". The color can only be seen by wizards and by cats, which is also referenced by Octarine Core's item lore. Spell Lifesteal is also shown on a character with greenish-yellow and purple particle effects.
