However, it first needs to be unlocked by speaking to the nearby NPC, Trossa, for a one time fee of 80,000. Another method to get there is using the fairy ring code C I S. Players can either use the games necklace to teleport to the Wintertodt Camp and run south-east until they exit the snowy area, then east afterwards. You will notice your Spellbook returning to the Standard/Normal Spellbook immediately. Alternatively, players can switch back to the Standard/Normal Spellbook by visiting Tyss again and choosing the 'I would like to stop using your Spellbook now' option, and he will lift dark magicks from your mind. Tyss can be found near the Dark Altar on the north end of Great Kourend. Players may speak with Tyss to switch to the Arceuus spellbook.
