Evolution I: Incarnon Form
Headshots charge Incarnon Transmutation; Alt Fire transmutes. Switching back will expend any remaining charge.
Gain an Auto Fire mode and Ricochet.
Mode switching is not instantaneous and has an animation equal to the weapon's reload speed.
Incarnon Form is activated by filling the Incarnon Transmutation gauge that appears under the reticule by achieving headshots and then pressing the Alternate Fire button. 9 headshots will completely fill the gauge. A full gauge is not required to activate Incarnon Form.
Instead of drawing ammunition from its reserves, the [Dual Toxocyst]'s Incarnon Form uses a separate "magazine" with each charge producing 30 rounds to a maximum of 270. Once all ammunition is expended, the [Dual Toxocyst] reverts to its normal form.
