Orbust

Overview
Orbust is an orb introduced in the demo release. Its name is a play on “or bust,” and may also be a reference to “robust,” reflecting the way it reinforces both offense and defense.
In play, Orbust has relatively modest benefits compared with similar orbs, so it is often most valuable when you can increase the value of its fired bonuses. It synergizes especially well with Balladin and 

Training Weight adds an extra Muscircle when Orbust is fired, which can make the orb much more worthwhile.
Essential Oil adds an extra Ballwark when Orbust is fired for the same reason.
Mask of Joy serves the same role as both of those items at once, boosting both effects together.
