USE AT OWN RISK
This data pack adds the "Tome of the Wither".
If you stand directly on top of a beacon for approximately 3 seconds, you get blinded by the beacon.
If you have any books in your inventory, they get turned into the tome of the wither.
This process fails if you already have a tome in your inventory.
This process also blinds you for 30 seconds.
You can also get one in creative only by typing "/trigger ssp_give".
The tome of the wither lets you choose what spells are applied to your character.
By sneaking with the tome in your offhand, you open the menu in chat.
The menu can only be closed by clicking on the exit button, or by taking the tome out of your offhand.
The menu lets you toggle spells by clicking on them.
Spells are green if they can be used, yellow if they are active, and grey if they are unable to be used.
There is also a reset all button to disable all of them.
Spells list thier cost in SP (Soul Points).
You have four soul points total.
Each spell when active takes 1 or 2 SP.
Each SP a spell uses reduces your max health by 2 full hearts.
Because of this, and the 4SP limit, you cannot die from spells.
Spells do not take max HP in creative mode.
The spells all are potion effects and are:
swiftness I 1SP
leaping I 1SP
strength I 1SP
slow falling 1SP
invisibility 2SP
fire resistance 2SP
night vision 2SP
swiftness II 2SP
leaping II 2SP
strength II 2SP
water breathing 2SP
luck 1SP
haste I 1SP
haste II 2SP
(not in that order)
If you click on a spell that is the same as an active one, but at a different level, it swaps between them.
Spells are lost if you die.
SP are regained if you disable a spell.
