Akheilos

The Akheilos is one of the three bosses released in vC1.6.

It spawns in the ocean and looks very intimidating, but it may be one of the easiest bosses because it does not attack. While it boasts a massive 3000 Health, the fact that it does not attack makes it easy to kill.

It also has good rewards, including 16 Raw Emerald and 8 Raw Fish. It is not as good as the Gorejaw for farming meat, but you can kill it over and over again to get enough Raw Emerald to make a full set of Emerald items.

The Akheilos is also a good source of EXP, awarding the player that kills it approximately 100 EXP points. However, there are still better EXP sources like Sun Trees.

There is at least one place where the Akheilos spawns, though only one area is known. There is a small island that seems to be made out of completely rock. It's between the center of the map and the edge. The Akheilos spawns on the bottom of the sea floor next to it.

Akhelios is also considered a small megalodon to some but nobody knows except Soybeen.
