Feat: Quicksoul
The elemental metal in your bloodline literally courses through your veins in the form of liquid metals like mercury, rubidium, gallium, and djezet, giving your actions a languid fluidity. You gain the trained proficiency rank in Acrobatics. If you would automatically become trained in Acrobatics (from your background or class, for example), you instead become trained in a skill of your choice. As these metals are largely toxic to organic life, you also gain the Toxic Touch action.
Toxic Touch 1 (poison)
Frequency once per day
Requirements Your most recent action was to Tumble Through, and you successfully moved through an enemy's space
Effect Make a melee unarmed Strike against the enemy whose space you moved through. On a hit, the target takes 1d6 persistent,poison damage and is Sickened 1 (or takes 2d6 persistent poison and is Sickened 2 on a critical hit).
