Morphball is a tech that allows the player to transform into a ball and roll. While activated characters are shown as a light blue ball bisected by a darker blue line.
Morphball can be used to access pathways that are too small for the player to walk inside. However, players in morphball cannot jump very high, and will need to switch back to normal form in order to get over obstacles.
To activate the morphball press 'F'. To switch to normal form, stand between two blocks and press 'F' again.
While in morphball form, clicking will drop a mine. The mine will detonate after a certain amount of time, or will detonate immediately upon contact with a hostile entity. The mine does considerable damage, instantly killing a unarmored player. Mines are subject to gravity, but do not roll down hills. The mines do very minimal terrain damage with a radius of 4 blocks.
This tech consumes 65 Energy per second. Deploying mines does not cost additional energy. Players still receive full damage, thus you can be attacked easily whilst going down hills.
