Skinwalker Staff

Staff, spellcasting focus, very rare (requires attunement by a bard, druid, or ranger)
  Used in shamanistic rituals to commune with wildlife, this staff is adorned with animal skulls and bones. This staff has 10 charges and regains 1d6 + 4 expended charges daily at dawn.
  Whilst wielding the staff you can expend 1 or more of its charges to cast one of the following spells, using your spell save DC:
  Charges Spell
  1 Animal friendship, speak with animals
  2 Animal messenger
  3 Conjure animals
  4 Dominate beast, polymorph (self only)
  If you expend the last charge, the skull on the staff withers and cracks, losing its magic. As part of an 8-hour ritual, the skull can be replaced by that of a beast slain within the last 24 hours. At the next dawn, the staff regains charges as normal.
  Rare variant: Remove the 4 charge spell options
