Place a few at edges of your base in turret mode and it will highlight nearby hostile creatures. Excellent way to detect piranhas in water near you as well. Warning: it also triggers on oviraptors for some reason. Can also be set to detect humans for PVP servers.
If u get a para DONT use it for battles (personal experiences) instead use it for prodicting an attack with its enemy sonar! So for all U players out there who keep on being attacked by tickle chickens and being decapitated get a para. It will do you good.
The parasuar has had its base damage buffed to 12, base weight buffed to 480, and it’s wild weight gain was raised to 9.6 per level. This makes parasaurs carry only slightly less weight than a mammoth. Parasaurs have had a huge buff.
