Enhanced Tier5 Tomes

This is just a simple English version of my Chinese MOD. I'm not very good at English, and I used DeepSeek to translate all the text. Please forgive any language or text issues.

In the original game, Tier 5 Tomes are unique items in a game, but their current strength fails to match their prestige. This mod significantly enhances the six Tier 5 Tomes, making them the ultimate goal for your build. Additionally, each tome skill now features a new enchantment exclusively for Mythical units, boosting their relevance and making your choice of tome even more important.

Adjusted AI behavior to prioritize researching Tier 5 Tomes and utilizing their skills.

Fixed a vanilla game bug where selecting "Book of the Nature Goddess" lacked a background graphic.

Potential Issues: Since this mod essentially overhauls the six Tier 5 Tomes and removes the vanilla versions, you may encounter issues unlocking related achievements.
