Around 15 minutes to beat this final boss. This boss was difficult for the wrong reasons. The hit box is insane to find. It turned out that if I just stayed at my character's spawn point (after returning from death) I would be on the right plane to connect with the boss but only after using a running jump attack. The best way to connect seemed to be to time my running jump attack around the nose of one of the dragons, when they were tucked in closer to the boss, so that I could make the jump. Usually I would get hit during the attack or while retreating to repeat it again. When I tried to connect with the boss without doing it this way I only connected an attack once. So it worked better to just use the spawn location as a guide. Really shitty fight in a very shitty game. Luckily the checkpoint was right at the boss and there is infinitie continues.
