Reaper Crew and Master Quest Cape are NOT required for the untrimmed Completionist Cape as of the June 2023 rework — they only gate the Trimmed version now.
Time estimates here are rough buckets, not measured unlike MQC's video-sourced numbers, these are inferred from each achievement's scope (X/N counters, single unlock vs. multi-step). Useful for sorting and rough planning, not a precise forecast.
Buying isn't a separate requirement once everything above is met, purchase from the Museum guard on the top floor of Varrock Museum for 5,000,000 coins — it's just claiming the reward.
Iron accounts: Tiers of Treasure leans on your own clue drops clue scrolls (and the caskets that unlock rarer tiers) only come from your own play with no Grand Exchange or player trading to fall back on — so rather than saving clues for later, do every one you get as soon as it drops. Treated that way, this tends to clear itself well before you're specifically farming for a missing tier.
Hardcore accounts: much of this list is already safe-death content dying downgrades a hardcore account to a regular iron one — but the game's safe-death rules cover a lot of what this cape asks for. Deaths inside Dungeoneering, your own player-owned house, a boss instance set to practice mode, and most combat minigames (Castle Wars, Barbarian Assault, the Fight Caves and the like) don't cost the status at all. The general rule is that if a non-hardcore account would keep everything on that death, it's safe for you too. Worth checking which side of that line a requirement sits on before writing it off as too risky to attempt.
