To use turret mode don't forget after setting it up to set the arthro to aggressive else they won't attack any target. Set targeting range to determine how far they'll shoot.

Arthro bites are actually quite torpor-worthy. Knocked out a low level Sarco with just a few bites from an Arthro with about 275 percent melee damage. Surprised the Dododex dev didn't add it in too.

Great base defense Dino on pvp... paired with a couple scorpions and this can be devistating. This dino will break the armor in one spit and then the scorpions will knock them out fast.

Not exactly the best combat mount, slow, stamina isn't the best, a little squishy. But a few high levels of these on base defence are pretty good. Put a few in the inner parts of your base (along with the spiders to slow them down) and the will have your enemies armour being melted in seconds!
