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 Bits
 * +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 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.
