The Minty Dragon

Being employed by such a being causes you to change in some ways. You more often find yourself bargaining with shopkeepers and making offers to potentional customers. You may grow a liking to breath mints and other refreshing foods and drinks. You become a member of the MintyDragon.Co family and the success of the company becomes a priority.

Level 1: Expanded Spell List

The Minty Dragon lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Bonus Cantrips

At 1st level, you learn the Light and Sacred Flame cantrips. They count as warlock cantrips for you, but they don’t count against your number of cantrips known.

Frosted Magic

Starting at 1st level, you gain the ability to enchance your spells with ice magic. You can add an extra dice of cold damage to your spell attacks. You can do this a number of your profficiency bonus +2 times per short rest. The dice start as d4s and upgrade to d6s at level 5, d8s at level 11 and d10s at level 17.

Level 6: Cold Bond

At 6th level your bond to your patron grants you a tolerance to cold. You gain a resistance to cold damage.

In addition 3 times per long rest using a Bonus Action you grow white dragon wings for 10 minutes, giving you a flight speed of 35ft. 

Ice Residue

Starting from 10th level, the ice from your attacks melts slower, slowing down targets. When you deal cold damage, the target has to make a dexterity saving throw. On a failed save the targets movement speed is lowered by 5ft. until it drops to 0ft., when the target receives a disadvantage on dexterity saving throws. If this effect has not been triggered the last round, the target regains 5ft. of movement.

Also, when in flight granted by the Cold Bond ability, you deal +1 cold damage on ranged spell attacks.

Draconic Vision

Starting at 14th level, your bond to your patron strenghtens, allowing you to cast Illusory Dragon (Cold) without a spell slot. Once you use this feature, you can`t do so until you finish 1d4 long rests.    (D&D Beyond doesn`t have Illusory Dragon available, so you`ll have to look it up somewhere else)
