wrong, I think it's wrong for him to use the spear or any weapon in general, it's more of a problem, the time in which the fire reaches the weapon, the wear and tear of the weapon, simply by raising his hand the MC could launch fire and control it, for what to fight with the spear in the dungeon and when he goes alone is a mistake, I understand it if he practices it to fight against humans, but with monsters it doesn't make sense.
Author here are a few mistakes : When thanking Naaza you wrote something like 'appriciate', it's 'appreciate'. Also about the previous chapter you forgot to add the MC's current level. Then about the development ability those can only be obtained by leveling up, which means you need to be at the very least level 2, however there is a special case which is Finn, he has a skill called 'Dia Fianna' which grants him the 'spearman' development ability only when he wield a spear. It's power depends on Finn's level.
