Someone asked me to make a Dwarven Elytrian Origin, so here it is!
You'll need the Origins mod and the Pehkui mod for this to work.
This is my first datapack so please don't criticize my work.

Icon: Redstone
Impact: remove_circleremove_circleremove_circle
Description: Dwarven tinkerers created wings out of steel and redstone, giving them the power of flight.

Positive:

Wings: You have elytra!
Blast off! : Launch 30 blocks into the air
Night Vision: Due to your time in the mines, you can see in the dark.

Neutral:

- Smaller: You are 1.5 blocks tall.

Negative:

More Kinetic Damage: You take more damage from flying into blocks and fall damage.
Light Armor: Your wings overheat with too much weight, meaning you can only wear light armor.
