This was way too much work, but I finally finished the third out of four dungeons! Not only that, a lot of edits to the existing content was made to enhance the experience a little.

Here are the full changelogs:

• Rock Bullet's description now actually says it needs Rock Shells instead of Physical Shells
• All the boss rematches uses a different version with the old drop rate and lower exp gain, while the original fights have their drop odds doubled 
• The Flatwoods Monster NPC on Flooded Power Plant 2F now has an additional dialogue if you talk with it a second time 
• Added a bunch of new enemies with new skills, items and gems 
• New Fairy and Dragon monster types added to the bestiary 
• Added a new form of Tsuchinoko that gives even more exp than the regular one 
• Bandages becomes Worn Bandages after use 
• Magic Amulet becomes Binding Amulet after use 
• The shopkeeper now sell Bunny Photos after the second dungeon 
• Hime's Limited Use Skills was replaced for Yanfly's Skill Restrictions to prevent some of the random crashes that script used to cause 
• Venka's Bestiary script received a couple minor changes to hopefully fix the extremely rare crashes that sometimes happened while exiting the bestiary 
• Long Bow's ATK changed from 38 to 48 and it now has a proper skill set 
• Being affected by Rage now makes your DEF 80% 
• Added an extra line in the intro for further context 
• Added multiple new NPCs stablishing the world a bit more clearly 
• Added a new human sprite and an angel sprite for the new... friendly? NPCs 
• The Cultist sprite is completely redraw to be more accurate to their role in the game
• The Shopkeeper has a box
• The Diary item now has more text covering some specific maps of the game that may be confusing for some players 
• In the bestiary, enemy level up skills now always appears under the "Underdog Spirit" skill 
• The Shopkeeper now has an additional dialogue before you defeat Princess Pygmy

I'm happy how the game is shaping up so far! No idea how long I will take with the last dungeon, but I will do my best for it to be as good as I can make!
