OSRS Scroll Box Calculator

How many clues can you stack?

Once you finish X Marks the Spot, clue scrolls drop as scroll boxes, and each tier stacks up to 2 to start with. A scroll box and the clue scroll you are working on share the limit, so one scroll and one box is a full stack of two. Each tier then goes up by one with its minor scroll case, by one more with its major scroll case, and every tier goes up by one with the Mimic scroll case, to 5 at most. Before the quest you can hold 1 clue scroll of each tier and no scroll boxes. Watson's Treasure Trail Statistics board in his house shows your limit for each tier. Nothing else raises it: no achievement diary, other quest or combat achievement tier does. The combat achievement tiers make clues of their tier drop 5% more often instead, and the clue chances on this page follow the tier you set for your monster.

A scroll case comes with the reward casket that reaches its count, and again with every casket after until you open it, so a case you bank or lose is not gone. Clues you finished before scroll cases came out count towards them.

The Mimic scroll case

The first time you beat the Mimic, the casket it came from also gives the Mimic scroll case, which adds one to every tier. Turn Mimic encounters on at the strange casket upstairs in Watson's house: then 1 elite casket in 35 and 1 master casket in 15 is the Mimic, and if you have never had one, your 25th elite or 10th master casket is one, or your next if you are past it. The elite and master clue rewards calculators work out what a Mimic casket is worth.

Full stacks and lost clues

When a tier is full, a drop of that tier is lost. With the clue warning on in your settings you get the message "You have a sneaking suspicion that you would have received" a scroll box and nothing drops; with it off the box drops but you cannot pick it up. Skilling rolls only for the tiers you have room for, so a full hard stack does not stop an elite nest. An easy to elite casket gives no master clue while your master stack is full, which is why the clue rewards calculators have a box for it, and this page ticks it for you when your master clues are full. The clue chances here are the dry calculator's, monster by monster, with the ring of wealth and combat achievement tiers that change them, and the boss gp per hour calculator gives the kills an hour this page starts from for a boss.

Juggling and Watson

Clue scrolls on the ground do not count, so you can drop one and get another. A dropped clue scroll lasts 61 minutes, logging out pauses it and it follows you when you hop worlds, so jugglers pick each one up and drop it again within the hour; the item despawn timer runs a timer for each one. Dropping scroll boxes does not get round the limit: picking up more than you can hold destroys the rest. Watson takes one each of easy, medium, hard and elite clue scrolls, opened from their boxes, and those do not count either; if your master stack is full when he has all four, he keeps them and gives you the master clue once you have room. Some hard and master steps hand you a sliding puzzle to finish before the next clue, and the puzzle box solver gives the moves for any of them.

Ironmen, Hardcore Worlds, free-to-play and Deadman Mode

Ironmen stack the same as everyone, and an ultimate ironman's stack lives in the inventory. On Hardcore Worlds the limits are the main game's, but clues go to your gravestone when you die and a Hardcore Worlds gravestone is lost for good, so the clues you carry die with you; resetting the character starts the limit again from the quest. Free-to-play worlds have beginner clues only, and only the beginner scroll cases work there. On the permanent Deadman world the limits and scroll cases are the main game's, except that a stockpiling charm in your inventory or looting bag lets clue drops stack past your limit. A stockpiling charm comes from breach bosses and monsters of combat level 200 and over, and an accumulation charm triples clue drops.
