Update time:

Sorry this is taking so long. My OCD prevented me from starting a quest and not finishing it, so I did complete Theodore's Quest before finally obtaining the God Weapons, I sort of wish I had grabbed the GW earlier, but was afraid getting them would lock me into only being able to do the final dungeon.

I actually reached the final floor where the boss gauntlet is located, but left because I kind of want my party to gain all of the Weapon Skills for the new weapons I acquired. Unfortunately, only the Eres Bow has been mastered while Albert and Gray refuse to level up their weapons beyond Lv. 5 to my discontent. So I've been kind of farming enemies around Isthmus Castle to gain the weapon skills needed.
