Vampir DataPack

The datapack was made using only vanilla commands.
Hi everybody. I made this data package myself and I want to tell you what is in it.

1) To become a vampire, you need to stand in the center of the ritual table and press the shift key.
2) Now, approaching any villager, approaching as close as possible, press shift and you will be able to drink blood, but the villager will receive damage at the same time
3) If you take the bottle to the ninth slot and bite a resident, then you will fill the bottle with blood. You can drink this later
4) The longer you live as a vampire, the more HP and power you will be given.
5) If you live as a vampire for more than 500 seconds, the sun will begin to "fade" until you are under the roof, or until night falls, or until you put on special clothes.
6) Water will also kill you.
7) A vampire can be easily killed with holy water and arrows smeared with this water.
8) To stop being a vampire, you need to drink the antidote, which is prepared on the ritual table. To do this, you need to throw a bottle of blood in the center of the table
9) To create holy water, you need to combine blaze powder + dragon breath + player's head.
10) To make arrows lubricated with holy water, you need to throw 4 arrows and a bottle of holy water into one block.
11) So that the sun does not burn the vampire during the day, you need to wear a leather bib, pants, shoes and the head of any player.
12) If you eat almost any human food for a vampire, then the effect of nausea and hunger will be imposed on you. Conversely, if an ordinary person drinks blood, the same consequences will be imposed on him
13) In order for the wither to work in the sun, you need to install a daylight sensor at coordinates 0 319 0 use the command "/setblock 0 319 0 daylight_detector"

P.s. I translated everything into Google translator, and there are errors in the text. Everything inside the datapack is in Russian, sorry, but I'm too lazy to translate into English
Have Good Day!
