This mythic icon of Rome dominates the battleground with its swordlike claws and razor sharp teeth. The balanced qualities of this beast make it an excellent all-purpose battle unit that every warlord wants to possess.
With the 2013-07-26 update the Bearwolf also becomes a looter when it reaches level 6. His behavior was changed from "favorite target: non-utility" to "favorite target: Resource gatherers, Stockpiles, City Center".
With the 2013-08-03 update the Bearwolf behavior was reverted but it kept the looting behavior with other words it still has the 2.5 multiplier on hit.
The Bearwolf is probably the strongest beast in early levels, it can solo cities around level 20 with ease. The Bearwolf is also a very strong city defender throughout the levels, specially against ground attacks. The weakness of the Bearwolf is that he is not viable in high levels and endgame. His damage is too low and it's no where near to being able to properly tank the damage of the defensive towers. There were rumors that this beast would get a buff for endgame but until now there are no changes.
