Soul Reaper

Youve learned that your soul can offer more than simply keeping you alive, through focusing your soul and learning the path of shinigami you have forged a blade from your soul, living and alert

Zanpakutō

3rd level soul reaper ability

Your Zanpakutō forms when you choose this subclass, acting as a silvered longsword, shortsword, or dagger, after a short or long rest the blade will reappear by your side if it was lost, and it grants you the ability to send souls to the afterlife through a konso

Konso:

as an action you can press the bottom of the hilt to a willing spirit or undeads forehead and send them to their afterlife

Shikai

7th level soul reaper ability

through training, dedication, and care, youve learned to hear your Zanpakutō’s voice, and through that have gained the ability to hear its name, allowing you to call their name and awaken your blade from its slumber, transforming your blade into its shikai form with a different appearance than that of its slumbering zanpakutō form.

as an action you call the name of your Zanpakutō and activate your shikai, which has your shikai origin effects for 1 minute or until you deactivate it as a bonus action, you can do this a number of times equal to your wisdom modifier

Shikai origin: fire

Your shikai formed from your soul with its burning passion and erratic energy, allowing you to call forth from it fire, which will grow as your soul and bond with your Zanpakutō.

when you activate your shikai your blade becomes wreathed in flame, dealing 1d6 extra fire damage, increasing to 1d8 at lv12, and 1d10 at lv17

Shikai origin: Ice

Sealed away and hidden, like your soul, your Zanpakutō has become akin to your cold soul, keeping wary of others and careful who you let in to see your soul.

as a reaction, when you get struck by an attack on your turn, you can release a burst of freezing cold that hinders the attack and lashes back at your attacker, roll 1d6 and reduce the damage taken by that amount, then deal the reduced damage back at your attacker as cold damage, this die increases to 1d8 at 12th level, and 1d10 at 17th level

Shikai origin: lightning

Your Zanpakutō has formed from your sporadic and energetic nature, allowing you to move faster than a normal person is capable of, quickening your strikes.

As a bonus action while your shikai is active you can strike with your zanpakutō and deal extra lightning damage equal to 1d6, this increases to 1d8 at 12th level, and 1d10 at 17th level

Reinforced Zanpakutō

10th level soul reaper ability

As youve grown stronger, so has your blade, from here on your zanpakutō can take the shape of a magical weapon in your possession and counts as magical for the sake of overcoming resistance

Enhanced shikai

15th level soul reaper ability

As youve grown, so has your blade, unlocking new strength from your shikai and allowing you to bring forth more energy to unlock the depths of your shikai

you take the next level of your shikai origin and can maintain your shikai for up to 10 minutes when it is activated

Shikai: fire

Your shikai has become more energetic, being able to extend beyond the blade and lash out at targets around you

As an action you can target a creature you can see within 30ft of you, you then cause an eruption of flame around them, the target and any creature within 5ft of it must make a dexterity save equal to 9+your PB+your wisdom modifier, dealing 6d6 fire damage on a failure, or half as much on a success

Shikai: ice

The energy from your icy strength has grown, allowing you to reinforce yourself with the ice from your shikai

while your shikai is active youre reinforced by a layer of ice like armor, you gain a +1 bonus to your ac, and an amount of temporary hp equal to twice your level, when the temporary hp is expended, the bonus increases to +2

Shikai: lightning

Your strikes become stronger and almost lashing as you rush from enemy to enemy before they can fight back while quickening your body

while your shikai is active your strikes cause your opponents to not be able to react, when you hit with an attack, that creature cannot make opportunity attacks against you until the end of your turn, your movement speed also increases by 15ft

Bankai

18th level soul reaper ability

Youve grown a bond with your Zanpakutō so strong youve learned the name of your bankai, making you strong enough to ignore calling the name of your shikai 

You no longer need to use an action to activate your shikai, and as an action you can activate your bankai while in your shikai state once per long rest, gaining your origin specific powers

once the bankai ends you gain a level of exhaustion from the strain of drawing out the power your bankai brings
