Inspired by the Dragon God herself, Tiamat's Fury comes with a powerful kick, for those brave enough to try it. Usually reserved for the top shelf of any tavern in a large city, Tiamat's Fury has a reputation of being a spirit that separates the common folk from the adventurer. Beware to those who finish the last shot... the Worm at the bottom could be there for more than just flavour! 

Potion comes with 3 d4 uses.

When a character drinks from this spirit, roll a d20. 

1- 5: Roll a DC 12 Con saving throw. User takes 2 d4 fire damage. Half on a successful save. 
6 - 15: Roll a DC 8 Con saving throw. User takes 1 d4 fire damage. Half on a successful save.
16 - 20: Potion has the following effect: 

You feel the power of Tiamat flow through you. After drinking this potion, you can use a bonus action to exhale at a target within 30 feet of you. 

The target must make a DC 13 Dexterity saving throw, taking 4d6 damage on a failed save, or half as much damage on a successful one. The effect ends after you exhale three times or when 1 hour has passed. Roll a d6. Damage is of the following type:

1 - Fire

2- Cold

3 - Acid

4 - Poison

5 - Lightening 

6 - Player's Choice of one through five

When the last use is gone, roll percentile dice. There is a 5% chance the Worm at the bottom is a Red Dragon Wyrmling. Roll initiative!
