Hellslinger

Hellslingers conjure and wield hooks of pure flame, storing and converting heat to fly across the Nether at blazing speeds.

Heat Storage: You are able to store heat that's used for your abilities while in the Nether or when on fire. You don't take any damage from fire.

Fireflight: You have natural elytra as long as you have heat stored. It slowly drains heat while in use, and will quickly degrade armour that isn't gold, netherite, a Wildfire Crown or enchanted with Fire Protection. You cannot use fireworks with these wings, and you are unable to wear regular elytra.

Flameswing: At the cost of some heat, you can fire an instant ray of fire with high range at blocks, lava or entities. If you hit something, you will be launched towards it. A larger amount of heat will be extinguished if you miss. You cannot use this whilst touching lava.

Heat Flip: You can use some heat to launch yourself backwards while flying. If there is an entity nearby when you use this you will gain heat and it will be damaged for 7.5 hearts, bypassing armour but not enchantments.

Scorching Stun: If you are damaged while flying, your elytra will be temporarily disabled for 5 seconds.

Nether Inhabitant: You naturally spawn in the Nether.

From the Flames: You are temporarily immune to lava for 3 seconds upon entering it, but have 3 less hearts.

Hydrophobia: You take damage from water, snowballs and potions.

Weak Body: You deal less damage, take more damage and move much slower when on or near the ground.

Sleepless: You cannot use beds.
