Hey guys. If u have still trouble with these guys, get a Sarco travel with u. Mount it or not is the same. Piranha´s flee from Sarco´s. U can have a Little Sarco, u not need a 100lvl+ guy. So u dont need to fight against these guys.
These piranhas are SOOOO annoying!One time I was passive taming and Equus and it ran into the water, Then about 2-4 piranhas came up and killed my Equus! I was so sad and I went and killed them. WildCard, If you see this lower the percentage of piranhas. Thank You!
