■ Desert Claw - is a global sponsored addon for the Dragon Survival that transforms your boring human! This mod significantly affects gameplay. Work in progress.

■ How to become a Desert Claw?

At the game's start, you'll be given a choice of several creatures to transform into. If you cancel your selection with ESC, you can return to it later via your inventory.
An alternative method is to use the Altar from Dragon Survival. Use JEI or REI for searching recipes/items/blocks.

■ Skills

Bloodlust - When you deal critical damage to non-undead creatures, your Blood Mana regenerates faster.
Charged Sprint - You run and sneak very quickly, but this makes you hungrier and less steady on block edges.
Desert Warmth - Your cold blood heats up in the desert, granting you Haste and Strength.
Tough Lizard - You can’t use many weapons, but as you age you gain extra damage and defense. Leveling up this skill grants +2 bare-hand damage.
Radiation Immunity - Radiation is rare in this world, but you are completely immune to it. Improved compatibility with other radiation-related mods (Mekanism, Create: Nuclear, Create: Nuclear Tech, The Wasteland Reworked, Radioactive, #forge radiation, Nuclear Science). Compatibility is still not perfect due to the lack of a standardized approach for applying negative radiation effects.
Night Vision - You can see clearly in the dark.
Stunning Roar - You unleash a terrifying roar, stunning everyone nearby. It even affects flying creatures and other players. The higher your level, the greater your roar radius.
Sharpened Fangs - Look at the block you wish to process, and your skill will act as a right-click with an axe. Allows you to clean logs, copper, and other blocks. If you use this skill on a log, you will sharpen your claws and gain the Strength effect.

■ Penalties

Cold Blood - In cold biomes you suffer from Weakness, and snow blocks inflict damage. If you get very cold, you may completely lose your ability to attack. Keep your lizard warm.
Truly Frightening - You really do look like a demon. Golems attack you, and even villagers are terrified of you! At least you can steal from them. Perhaps a village hero might make villagers more tolerant for a while.
Clawed Paws - You can proudly say you have paws! But this severely limits the use of most tools and weapons. While other dragons compensate with levitation, you’re simply a beast.
