Minecraft Earth:Boost

A boost $$ was an enhancement to a player ability. A boost's duration and intensity depended on its level. A player was able to spend rubies in the store to purchase boosts.

Effects
Boosts were available as levels I, II, and III. The level of the boost determined its duration, intensity (if applicable), and cost.
 * Level I boosts lasted 10 minutes. One level I boost was able to be purchased for 10 rubies.
 * Level II boosts lasted 15 minutes. Five level II boosts were able to be purchased for 75 rubies (15 rubies per boost)
 * Level III boosts lasted 30 minutes. Three level III boosts were able to be purchased for 100 rubies (33.3 rubies per boost)

Boost minis
Boosts could also be obtained by scanning the undersides of collectible figurines called boost minis. There were 24 boost minis to collect, with each one providing a different type of level 1 boost. Each boost mini had an 18 hour cooldown period before it could be used again.

Placeholder boost mini icons are present in the files of earlier versions:
