Staff Rocket Boost

Staff Rocket Boost, also known simply as Rocket Boost, is 's up special move in Super Smash Flash 2.

Overview
When performed, Krystal plants her staff on the ground in front of her before purple flames emit from the bottom, boosting her a short distance upward. Opponents hit at the start of the move are dealt 4% damage and weak knockback which also meteor smashes them. Opponents hit as Krystal rises are dealt 11% damage with strong upward knockback, and there is also a sweet spot just as she begins to rise that deals 16% slash damage with slightly stronger knockback.

The move is primarily useful for recovering, being Krystal's main way of gaining vertical height. However, both its vertical and horizontal distance are quite poor, and it also leaves Krystal helpless afterward.

Origin
The Staff Rocket Boost is the second Staff Upgrade that Fox obtains for Krystal's Staff in . It grants Fox the ability to boost himself straight upwards with Krystal's Staff to reach high ledges. However, this can only be used in unison with Rocket Boost Pads, which are located on the ground in predetermined places around Sauria. Like most Staff Upgrades, using the Rocket Boost also depletes Fox's Staff Energy Meter, which can be refilled by collecting Staff Energy Gems, usually dropped by Magic Plants.

Trivia
