Arrow of Fire

this arrow deals weapon damage as well as an extra 1d4 Fire damage then bursts in a 10 foot area and any creatures within the radius other than the target must make a DC 14 Dexterity Save or take the Fire damage as well, that continues to burn for 1 minute. When a creature enters the burning area for the first time on their turn or starts their turn in the area takes 1d4 Fire damage.

Any creature that takes the initial Fire damage is considered burning for the duration unless they take an action to dose or put out the flames or an ally uses their action to do the same.
