Elemental Link

You enhance your connection with the source of your elemental power. You gain the following benefits depending on your subrace.

• Air. As a bonus action, you may grant yourself a flying speed equal to your walking speed until the start of your next turn. You can do this a number of times equal to your proficiency bonus and you regain any expended uses after a long rest.
• Earth. When you take bludgeoning, piercing, or slashing damage, you can use your reaction to grant yourself resistance to the triggering attack.
• Fire. Whenever you deal fire damage, you deal additional damage equal to your proficiency bonus. If the source of the damage only targets one creature, all creatures within 5 ft. (excluding you) take the additional fire damage.
• Water. You learn the Water Walk and Wall of Water spells. You can cast each of these spells once without expending a spell slot. Once you cast either of these spells in this way, you cannot do so again until you finish a long rest.
