The double Surge codex is an item that can be read to unlock an upgrade to the Surge ability, giving it an extra charge with a separate independent and hidden cooldown. The double Surge ability is not functional in the Wilderness when opted into PvP.
It can be created with 750 codex pages using the lectern. It is consumed upon use. This version can be bought from or sold to other players or the Grand Exchange, but the untradeable version only requires 500 codex pages.
Acquiring the codex pages required for this codex would take approximately 9 hours assuming an input of around 12 codex pages per agility course lap, or 84 codex pages an hour.
Once the Surge ability has been upgraded, reading this codex has no effect, and the codex is not destroyed upon attempting to read it.
