This mod adds a new Deathclaw Meat ingestible and integrates it into the game via death loot from Deathclaws. The item doesn’t heal very well, but it grants a temporary +5% damage effect.
For Fallout: New Vegas (and TTW) there’s also two new crafting recipes for a Roasted Deathclaw and a Spicy Deathclaw Kebab. Roasted Deathclaw is basically free, it satiates hunger slightly more. Spicy Deathclaw Kebab has significantly better effects but requires a lot of ingredients.
