Players are given a banker's note which allows players to use note-able items on it to turn them into banknotes or unnote them. Items must be used on the banker's note.
The "Activate" option allows players to note and un-note items in one action with a quantity of the player's choosing. An item must first be used on the banker's note in order for this to work.
As the player is given an item upon unlocking this relic, it must be unlocked in a bank.
Bringing noted supplies such as food and potions for combat, allowing for longer trips and safer bossing. Loot can also be noted to save on inventory space.
Gathering skills such as Mining, Woodcutting, and Fishing no longer require a trip to the bank to keep the supplies.
Creation skills like Fletching and Herblore can be easier trained away from a bank or in tandem with other skills by bringing noted supplies and noting the results.
For Construction, logs and planks can be unnoted and noted at a Sawmill to save trips to a bank. Unnoting supplies while building is also a good substitute for a Servant.
As the Entrana monks don't check for noted items, the player can un-note weapons and armour on the island, which can be useful for certain clue steps and quests.
