Tempus' Blessing

Requires being favoured by the god of Tempus

You cast an enchantment on your weapon, which promptly erupts into flames. You feel the power of the god of war flowing through you granting advantage on intimidation checks made during this time. 

The effect lasts for 5 minutes, and aditionally gives your weapon an additional 2d6 fire damage on top of your normal weapon damage. 

When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
