Ash's scabred

Alahla's Sheath (no attunement required, but only works under those who took the Oath of the Fighter)- Once per initiative, you may speak the words on the sheath to gain one of the following effects for up to two attacks in the turn:
-Gain a d8 when rolling to hit with the weapon stored in the sheath
-Double the damage dealt by the weapon. This includes damage dice from sneak attack.

Consider the oath a special thing that tied you to this sheath.
