Hey guys got a question here

So i doubt any of you will help or even know what im talking about but hey worth a shot.

Ok so on Fridays I run a d&d group, we use a classless system based off of bleach that i had found, and my players are enjoying it. But the thing is we have a mechanic that impliments reiatsu/ spirit presure and it soesnt have much going for it. Other then the base stuff in the book.

Ive already created a few zanpakto abilities that consume this stat but for some reason nothing else is coming to me.
The zanpakto types in my game are:
A sand whip.
A pair of fire and ice blades.
A stopwatch that controls local time.
And a guantlet with a pair of spikes that drips poison.

So what im asking for is other things to use reiatsu on and maybe a few sword abilities

Only those that are spiritually aware can use these rules for Reiatsu. Normal humans and animals cannot use the skills
presented below. A normal human is defined as a character without a racial feat. A Human that takes the feat Spiritually
Aware negates this penalty. All uses of Reiatsu defined here are Supernatural Abilities.
Increasing Strength with Reiatsu.
By expending 4 points of Reiatsu as a swift action, you may increase your strength by 2 for lifting capacity. You may do
this as long as you have reiatsu. The bonus to strength lasts until the end of your next turn. You may spend multiples of 4
to have greater effect on your strength. For effects that are limited to strength modifier, increasing your strength in this
matter increases that threshold as well.
Increasing Speed with Reiatsu
By expending 4 points of Reiatsu as a swift action, you may increase your land, fly, burrow, swim or climb speed by 10
feet. This bonus lasts till the end of your next turn. You may spend multiples of 4 to have greater effect on your speed. You
may also spend multiples of 4 to increase multiple different speeds.
Increasing Jump Height with Reiatsu
By expending 1 point of reiatsu as a swift action, you may increase a single jump check by 1 point. You may spend
multiple reiatsu points to have a greater effect on your jump check.
Increasing Intimidate Checks with Reiatsu
By expending 5 points of reiatsu as an immediate action, you may increase a single intimidate check, including a soul
crush attempt, by 1 point. You may spend multiple reiatsu points to have a greater effect on your intimidate check.
Improve Damage with Reiatsu
By spending 4 points of reiatsu as an immediate action, you may add 1 damage to a single damage roll. This bonus lasts
for only one attack. You may spend in multiples of 4 to add additional damage to the roll.
Improve Defense with Reiatsu
By spending 6 points of reiatsu as an immediate action, you may add a +1 deflection bonus to either your next defense
roll or fortitude, reflex or will save. You may spend in multiples of 6 to greater effect.
Increasing Hit Rating with Reiatsu
By spending 6 points of reiatsu as a swift action, you may add +1 to your chance to hit an opponent. This bonus lasts for
one attack. This may be spent in multiples to get greater effect.
Healing
When you heal a character with reiatsu healing, you also restore an equal amount of Reiatsu as the amount of hit points
you heal.
Recovering Reiatsu
You may take a full-round action to recover your spellscore times 10 in reiatsu. This cannot go above your maximum
reiatsu in this fashion. This can only be done once per encounter.
Reiatsu Burn
Should your reiatsu drop below 50% you are fatigued
Should your reiatsu drop below 25% you are exhausted
Should your reiatsu drop to 0 or below you become unconscious until you receive at least 8 hours of rest.
Should your reiatsu be below 0, you are sensed as having a reiatsu rating of none.
Reiatsu regenerates at a rate of 1 point per point of spell score per day times effective Reiatsu level. If you receive full
bedrest for that day your reiatsu regenerates at a rate of 2 points per point of spell score per day times effective Reiatsu
level. If you eat during that day your results are doubled.
Captain Level Reiatsu
Average Captain level Reiatsu is above 500
Automatic Soul-Crushing
All beings exude an aura of reiatsu as they become more powerful. Divide your Reiatsu by 50 rounding up to the nearest
whole. This is the Soul Crush check you automatically display when you are not hiding your reiatsu to those within 30 feet
+ 5 feet per level of you. Hiding your reiatsu to negate this does so on a 1 for 1 basis of the check (IE If you had a Reiatsu
of 1,000 then you would automatically be exuding a 20 Soul Crush check against everyone within 30 feet. If you wanted
to not have this automatic check, you could roll a Bluff check. Getting higher than a 20 on the bluff check would negate
your Automatic Soul-Crush.)

So im asking for any suggestions you guys could pitch to me.
