Elemental strikes

lvl 3
Whenever you hit a creature with a weapon attack you may add 1d6 lightning damage or 1d6 fire damage, when you use one type of damage you cannot use it again until you roll a 17+ on an attack die, this resets one of the damage types(your choice) and adds 1d6 to it for the next use, you may use this damage type on the same attack as you reset it but you cannot reset a damage type after you deal the damage.
You can only use this damage once per round per weapon.
Every 3 levels you gain an extra damage type for this ability. At lvl 6 you gain ice damage, at lvl 9 you gain acid damage and at lvl 12 you gain force damage.

Windfury

lvl 5
On the first attack you make each of your turns roll a d6, on a 4-6 you may attack again, if you attack again repeat this roll, on a 5-6 attack again, if you attack again repeat this roll, on a 6 attack once more. 

Elemental overload

lvl 7
Whenever you reset a damage type from Storm and Fire you gain a buff related to that damage type:

• Fire: You gain temporary hit points equal to twice your proficiency modifier, this extra hit points are lost at the start of your next turn.
• Lightning: You overcharge, whenever you take damage reduce that damage by half your proficiency modifier rounded down.
• Ice: Whenever a creature hits you with an attack it gains disadvantage on it's next attack against you.
• Acid: When a creature hits you with a melee attack reduce the damage the attackers weapon deals by -1 after the damage.

Elemental crash

lvl 11
As an action every creature on a 20 ft sphere centered on a point you can see within 60 ft makes a dex saving throw against your spell dc. A target that fails the saving throw receives 1d6 damage from each of your element types. For each creature that fails the save reset one of your elemental damages from elemental strike, this reset activates elemental overload even if the elemental damage was available. On a success a creature takes half damage. You can use this ability a number of times equal to your proficiency modifier before finishing a long rest.

Spiritual link

lvl 15
As an action you may cast the warding bond spell on a number of allies equal to your proficiency modifier, they don't get resistance to all damage, instead creatures affected by this bond divide damage equally when one of them takes damage.
