You have ingrained a sense of loyalty and trust between yourself and the Vukah people. The Vukah will not attack you, considering you to be friendly to them. (Corruption still may interfere with this.)
As an action, you can call any nearby Vukah to your aide, as in the Conjure Woodland Beings spell. (Vukah Warriors and Rangers are CR 2 creatures, and as such, only one can be summoned in this way at a time.)
