BOOSTS are power-ups that fall from the top of any Sector at set intervals based on your LUCK Attribute. They drop randomly and cycle through all possibilities. You can catch them with your Heart for an immediate boost, or tap them to save them for the most opportune time.
Boosts will periodically drop from the sky during sectors at a fixed interval. The higher your LUCK Attribute is, the more frequently they'll drop.
For some Sector Bosses, you will want to make sure you horde Boosts to save them until the end, especially if you're easily breezing through the sector's waves.
The Health Boost restores an additional 75% of your current HP. It is best to use it tactically when your health is at its lowest for increased gains. If you use it while you nearly full health, the effect will be extremely minimal.
Invincibility is a very powerful boost. It makes your Heart invulnerable to damage for a short period of time and can also stack. If you save up your Invincibility Boosts, you can use them all together to add additional time to the Invincibility Timer.
The Speed Boost temporarily removes all Cooldowns from your REVOs so that you can Fling as fast as possible. Keep in mind that REVOs will have to de-spawn at the top of the Sector in order to come back into the Action Bar for Flinging.
The Power Boost doubles your REVO damage, allowing you to melt monsters and bosses alike. This effect lasts for a short period of time and can be stacked with additional Power Boosts for increased time but not increased Power beyond 2x.
In Limited Fling Sectors, the Fling Boost will award you additional Flings.
