Mariner

 Even while he was fighting indirectly against Poseidon, Ryan couldn't pull his punches, so he flew around the country in his draconic form since he would have access to more mana and recovery. Thus, he would be able to summon more golems and faster. Considering how effective they had been until now, there was no point in wondering if they would surpass the level cap of Ryan's human form. Thanks to that, Ryan also began to imagine if he shouldn't wall the entire continent with those golems. If he gives them the order to emit a cold breeze, they will be able to freeze everything around, even the ocean. However, that kind of strategy was flawed. The first reason was that it would take too long. The second reason was that Ryan would essentially give fuel for Poseidon to increase his powers even more. Every time his golems are defeated, Poseidon will grow stronger. They will be defeated since the monsters in the oceans will undoubtedly try to destroy the said wall.
