ARK: Survival Evolved & Ascended Companion
Tips & Strategies
A well imprinted karkinos with really high health can be effective against reaper queens since they don't get torpor from it's attacks and can jump away if you are about to get pushed into molten element of angry rock drakes and/or spinos just keep in mind your karkinos will probably get flung as soon as you dismount. Always make sure you have a glide suit so you can get back to your crab safely as megas and carnos will suddenly aggro on you. Also good for underwater exploration albeit it is not built for speed eels and cindaria will not aggro karkinos. Karkinos can also be used to tame just about anything sarcos or smaller since it can grab them and you can use a longneck/crossbow while mounted and it won't drop them when you dismount. Do not overestimate it's climbing ability it doesn't jump as high as it looks.
More Karkinos Utility Tips
If you're carrying a tamed Doedicurus in your claw the Doedic will automatically start harvesting any stones you hover him over. Just start pumping points into your Doedic's weight because it will stop at about half of its own carry weight. I've yet to discover another tame it will work with though...
Alright not exactly my tip, but heard this from the YouTuber pterafier. He said that using a Crab with a Turtle with C4 strapped on it is a good seige device. Put C4 on Turtle, then use Crab to throw the Turtle at a base. Detonate the C4, blowing up the base where the Turtle is at. I'd recommend watching Pterafier, he has a lot of tips on his channel.
The Karkinos is considered a large predator and therefore does not aggro other predators when ridden (with the exception of other karkinos, rock drakes, etc.), making it a great mount for relatively safe traveling!
HOWEVER!!! Smaller predators WILL attack if your karkinos is holding a prey creature in its claws, so keep this in mind while transporting tames and wild creatures!
