Booster Cookie

The Booster Cookie is a Consumable that can be consumed for multiple benefits that last for 4 days. Multiple cookies can be consumed at once to increase the duration.

Obtaining
A Booster Cookie can be bought from the Community Shop using Skyblock Gems, or from the Bazaar for.

Elizabeth will give every player one untradeable Booster Cookie for free, and she will sell you additional Booster Cookies for 325 Gems each, with no discounts for buying the bundles of six or twelve Cookies she offers.

Ability
The Booster Cookie grants the player the following abilities for 4 days:
 * Ability to gain
 * +20% Skill XP
 * +15
 * Keep and effects on death
 * Permanent flight on your Private Island
 * Access /auction (/ah), /bazaar (/bz), /etable (/et), and /anvil (/av) anywhere (/ah command can't be used in dungeon)
 * Ability to toggle specific Potion effects
 * AFK immunity on your Private Island
 * Sell items directly to the Trades menu

The Booster Cookie's duration is real-time, meaning it will continue to count down even when the affected player is offline.

The number of bits a player can earn depends on their bit multiplier. A player's bit multiplier can be increased by getting a higher Fame Rank. The number of bits that can be earned per cookie is 4800 * (Bit multiplier).

Trivia

 * , There is currently a bug that when going between servers in SkyBlock, that the booster cookie boost can randomly bug out and will be removed. This is not visual or temporary, the only way to get back the cookie boost is through consuming another cookie.
 * The booster cookie at first sight look like a "Pay to win" mechanic. This is partially true, but to a limited sense. The main point to adding this and allowing it to be sold was to crack down on in-real-life trading (Players trading players money for in-game cash). This was due to massive amounts of scamming, so it was decided this was optimal. It costs a lot to make it truly pay to win, but its also safer for players and the money directly goes to financing and improving the server. Players who do not pay real money are still able to obtain the cookie, however. The "pay to win" players would find a way to get in-game cash via other means regardless.
 * There is an option to buy more cookies at once from Elizabeth, however buying more will not get you any extra or at a discount compared to simply buying one cookie at a time.
 * There is a purchase limit of 192 of these per day.
 * The Booster Cookie that a player is given for free by Elizabeth cannot be sold to the Bazaar.
 * Toggling a Potion effect does NOT pause it, but instead it simply stops the effect from working on your player. Any duration timers will still tick down as normal, even when toggled.
 * The amount of bits from each booster cookie is effected by your Fame Rank.
 * It takes roughly 10 hours to get all the bits out of a cookie. You can afk and still get bits if you don't have enough time to actually play the game.
 * You can profit off booster cookies by buying items from the bits shop that make profit on the auction house. As of March 2021, enrichments seem to be the best one and have decent demand so you shouldn't have any problem selling them. There's a site called skyblockutils that has a bits to coins section that shows the best ones the sell at the time. Although keep in mind some enrichments might not be good demand. Intelligence, strength, and sea creature chance enrichments seem to have good demand.
