Viking: Battle for Asgard/Skills

Although Skarin starts the game with all the abilities he needs to complete the tasks he faces, these are fairly limited and will seem very repetitive after fighting for some time. To make up for this, Skarin can learn new abilities at arenas. There is one arena to be found on each island.
 * Niflberg: the arena is found just east of the ruins, on the coast at the very southeast corner of the island.
 * Garcliff: ??
 * Isaholm: ??
