A Roblox RPG built around grimoires, races, classes and dungeon runs, with PvP layered on top and a Black Clover flavour throughout. Codes hand out Yules, timed mastery and Yules boosts, and the tickets and removes that let you reroll a weak setup.
AGREED (2 independent voices: AllThings.How, iGeeksBlog; GAMURS network counts as one voice) for the 3 code(s) in the codes list. REWARD NOTE on ULTAMAYT: printed reward is iGeeksBlog's; other wording: AllThings.How: 500,000 Yules and a 15-minute 2x Yules Boost. REWARD NOTE on GUIZERAYT: printed reward is iGeeksBlog's; other wording: AllThings.How: 15-minute 2x Mastery Boost. SINGLE-VOICE, try-only, NOT in codes: open sesame (1 Open Tower Scroll - AllThings.How). DISPUTED, try-only, NOT in codes (listed active by one source but expired by another): 1 yule (active: iGeeksBlog, AllThings.How; expired: iGeeksBlog); Yagami (active: AllThings.How; expired: iGeeksBlog); car (active: AllThings.How; expired: iGeeksBlog); bros a slime (active: AllThings.How; expired: iGeeksBlog). WORKER NOTES: Two counting voices with a STATUS DISPUTE on 4 codes: AllThings.How (updated 2026-09-04) lists Yagami, car and bros a slime as WORKING, while iGeeksBlog (verified 2026-10-01, updated 2026-09-30) lists the same strings in its EXPIRED list in all-uppercase (YAGAMI, CAR, BROS A SLIME) - iGeeksBlog is the fresher voice, so treat those three as likely expired. CASING: iGeeksBlog prints its whole expired list in uppercase, while AllThings.How prints the same strings in lowercase/mixed case; code_map keys use the AllThings.How casing where it exists. '1 yule' is stranger still: iGeeksBlog lists '1 yule' as ACTIVE and '1 YULE' as EXPIRED in the same article. 'open sesame' is active only in AllThings.How and appears in neither iGeeksBlog list. Not the same game as Black Grimoire Odyssey (a separate title with no code system yet, per Common Sense Gamer, outside this cluster). No roblox.com/games/<id> link printed in fetched text.
