The Blessings of Icarus

This is a datapack that gives players permanent buffs every time they burn an elytra. The buffs will only be applied, however, if the player is not currently wearing an elytra. So it’s quite the choice. Do you wear an elytra, or do you get some good buffs. The buffs are tracked per player, so multiple players can have different amounts of elytras burned, and therefore different amounts of the buffs.
As a note, an elytra will only be counted as burnt if the player throws the item. If an elytra is put in a chest and the chest is broken, that will not count.

By default the buffs will cap once the player has burned 100 elytras, however this cap can be changed via the in-game settings menu. Each individual buff can also be disabled by the settings menu. To find the settings, use /trigger tboi.info and click on the settings button.
