The Relic version of One Horn, Oldhorn is extremely resilient with 2.4 million health. Assuming that Battle Cats runs at 30 frames per second(fps), then Oldhorn does 30,000 damage per second(dps). It slowly encroaches towards your base with a range of 80px.
When you first encounter this time traveling terror, it's the only thing in the entire stage, making it easy to build an entire set dedicated to defeating it. Freshman Cat Jobs makes this enemy very easy by weakening its damage down to 120 per hit. Thamaturge can also do this job too. You should also slow it down or knock it back with cats like Li'l Nyandam orUrurun Wolf. Manic Dark Cat is extremely good against Oldhorn since it has a extreme amount of DPS when stacked and can take down Oldhorn in a matter of seconds.
In the next stage it appears in, there are 3 of them inside the base, yet they spawn very separated, meaning you can dispose of one before the next one spawns.
