Rosie (supplies) is a merchant located on the island of Waiko from whom the player may buy supplies. Supplies are used to explore the Uncharted Isles; costing 25 chimes each. This can be reduced 5 times (−3 chimes each) to a low of 10 chimes each by purchasing the Supplies Cost Reduction reward from Boni at the Waiko Reward Shop.
Rosie will supply the player with 5 free supplies daily, her supply box storing up to a maximum of 50 supplies, claimed by clicking on the crate next to Rosie's merchant stand. If collecting the free supplies would put the player past their current supplies cap, the additional supplies will be lost. Attempting to collect the daily supplies while at the maximum number of supplies yields the message: You already have the maximum of [X] supplies. The initial supplies cap of 200 can be increased four times (+200 supplies each) to 1000 by purchasing a Supplies Cap Increase from the Waiko Reward Shop.
For the first week, Rosie sold supplies at the base rate of 50 chimes each. This was reduced to 40 chimes after the 1 August2016 update. On 10 October, this was further reduced to 25. Rosie's supply box was also updated to store up to 50 supplies for players, increased from the previous 5. Along with this update, the supplies crate was filled with 50 supplies for all players.
