Incineration tribesmen are often assumed to be connected to the Fire type upon first hearing about them; however, the traits possessed by this tribe are actually very diverse, including the ability to transform into half-orcs.
In worlds of high difficulty levels, transformation abilities face virtually no restrictions and can further enhance the individual's strength due to these changes.
Transformation itself aims to increase one's strength unless it involves changing into an energy form or similar existence, whereas physical transformation only brings about greater enhancement.
"When I was surrounded and attacked, that horde of vile beasts... Well, transformation situations are somewhat easy to handle, mainly their use of military array formations put too much pressure on me alone. But adding you to the mix changes things, though we still need to fight quickly; otherwise, if other tribes come to their aid, we might not be able to hold them off. Do you have any special skills?"
