Roll Rat
Calculate expected resource yield per node for any dino. Select a node type and harvester.
Each hit on a node generates resource drops. The game randomly picks a resource from the loot table for each drop. Higher melee depletes the node faster, which can reduce total drops. The "best" melee is where you get the most drops.
Compare dino harvest yields from creature corpses. Select a corpse and up to 3 harvesters to compare.
Each hit on a corpse generates resource drops based on damage dealt. The game randomly picks a resource from the corpse's loot table for each drop. Higher melee depletes the corpse faster, which can reduce total drops. All dinos get the same resource distribution from a given corpse — the difference is total drops from base damage.
The Roll Rat is a tamable, herbivore creature in ARK: Survival Ascended. It belongs to the Farmer category.
At 850 base HP, the Roll Rat is quite durable. Melee starts at 100% - respectable melee power that scales with level-ups. Its base Stamina of 300 gives it moderate endurance. Weight capacity starts at 400, giving it a solid weight pool.
The Roll Rat is passively tamed - approach it carefully and feed it by hand without knocking it out. Its preferred food is Giant Bee Honey.
Once tamed, the Roll Rat is primarily used for resource harvesting, excelling at gathering specific materials. It gives live birth after a gestation period, making breeding straightforward. Defeating one in the wild grants 7 base XP. It can be cloned at a Cloning Chamber for 0.45 Element plus 0.01 Element per level.
