In the end, Ryan managed to find two solutions to the problem of survivability of his trolls. The first was pretty cheap. The second wasn't so cheap. Most of the time, when Ryan uses Seal to create magic items, they ended up getting the elemental properties of the monsters. Still, sometimes that doesn't happen with some defensive items and accessories. For some odd reason, whenever Ryan created a magic weapon, magic armor, or magic shield, it always created something that had elemental resistance or extra damage with the ice nature. However, Ryan managed to make some items that increased the troll's overall defense instead of elemental defense.
The not-so-cheap solution relied on magic tomes. Since the troll's Fire Resistance wasn't that strong, Ryan decided to make his monsters learn Lesser Fire Enchantment. That cost him two hundred five thousand coins, but it couldn't be helped.
