Monk Took Book Progression Guide: From Shelf 1 to Shelf 5

The route, on verified data

Most progression guides guess. This one doesn’t have to: Monk Took Book’s achievement list doubles as an official progress map, with unlock rates marking exactly where the community thins out at each stage. The route below strings those milestones in order — every percentage is the official figure captured September 13, 2026, six days after launch.

Stage 1 — The docks (92% club)

Milestones: Checkout common book (96.7%) · Kill a rat (93.0%) · Unlock shelf 1 (92.4%)

The opening every player shares: first common book checked out, first rat dispatched, first shelf unlocked. Nothing here needs optimization — it needs completion, because the tutorial achievement and the first vermin kill are free progress. The only decision that matters this early is the one the shelf organization guide hammers: build the symbol zones now, while the library is small enough to change.

Stage 2 — The rarity ladder (86% → 47%)

Milestones: Checkout uncommon (85.4%) → rare (82.2%) → very rare (66.8%) → unique (47.2%) · Unlock shelf 2 (78.2%) · Buy torch and dagger

The rarity ladder is the game’s own progress meter: five checkout achievements prove the collection climbs from common to unique books, with the unique tier as the stage’s wall — barely half the players have checked one out. Vikings enter here at the grunt-and-archer level (the vikings guide), which is why torch (77.0%) and dagger (73.9%) top the shopping list. The perks guide marks shelf height (65.0%) and book carry (58.5%) as the community’s first perk buys.

Stage 3 — The raiders arrive (63% → 47%)

Milestones: Unlock shelf 3 (63.3%) · Kill a raider (57.5%) · Checkout unique book (47.2%)

This is where the curve steepens: shelf 3 costs the majority their first stall, and the raider tier marks nights that actually bite. The confirmed tool answers escalate with them — crossbow (37.2%) and holy cross (37.2%) are bought on pace with the ghost achievements, and the night orders guide becomes the difference between evenings that pay and evenings that cost.

Stage 4 — The deep build (38% → 23%)

Milestones: Kill a fire archer (40.5%) · Banish a ghost (37.7%) · Kill a berserker (36.9%) · Unlock shelf 4 (31.8%) · Perish (25.8%) · Exorcise the Dread Abbot (23.2%)

The back half of the roster lives here: fire archers and their bucket-and-well loop, berserker melee pressure, and the abbey’s first confirmed named boss — the Dread Abbot, faced by 23.2% of players (his page). The perk deep-end opens too: double jump (10.2%) and max health (10.0%) are this stage’s toys. And Perish at 25.8% is the stage’s honest warning — the difficulty settings exist for the nights that outgrow you.

Stage 5 — The 9% club

Milestones: Unlock shelf 5 (9.2%) · Complete thy collection (8.6%) · Sell shelf (8.1%)

Under one in ten players reaches the final shelf, completes the sacred collection, or sells a shelf back. These three are the run-defining achievements — they demand everything the earlier stages built: the filing system that survives weeks, the Blessings income that funds shelf 5, and the night discipline that keeps the collection pristine. There is no shortcut in the achievement data, and that is the point: the collection is the game.
