Embracing Thunder

Starting at Level 6, you have embraced the Thunder and Lightning flowing through your soul.

You are now immune to Thunder and Lightning damage, and you may deal Lightning or Thunder damage at will, and you may use your Wisdom for the attack and damage dice.

If you choose to deal Ki Empowered Strikes with these, then there is a 10% chance that your target becomes paralysed when struck.

After you use one of these spells, you can spend 1 Ki point next round and channel your thunder to form a lightning aura around you, adding temporary hit points equal to 20 + your Proficiency Bonus.

Elemental Mastery

By mastering the Thunder flowing in your Ki, you achieve a new set of abilities that can be used by spending Ki points and one final spell. Your final spell is Chain Lightning. After using the spell, you are able to make an unarmed strike as your bonus action.

With your Thunder being mastered, a new array of abilities are at your disposal.

You can spend 1 Ki point to cast lightning on any melee weapon or quiver of your choice so that they deal Lightning damage. This effect lasts until 3 rounds pass. You can only cast on one target at a time. 40ft.

You can spend 1 Ki point to create a duplicate of any one target of your choice whether it be an object or life. The duplicate will be forged from pure Lightning and you are able to control it as your action. You cannot control it and have a bonus action. If you want to create a duplicate of a living form, it will cost 3 Ki points per target. 45ft.

You can spend 1 Ki point to release a shock that paralyses one target. 5ft.
