About this Mod
Villagers now generate with random aptitudes for certain professions. When levelling those professions, provide the villager with a Tome of Aptitude to unlock extra trades! No more unfortunate accidents for librarians with bad enchantments or clerics with no ender pearls!
Future plans:
Special abilities for high-aptitude villagers, e.g. librarians upgrading all enchants on a book by 1 or rerolling them within same rarity.
Nitwit aptitudes: convert nitwit to a random profession with a uniquely high aptitude!

Aptitude server crashes on startup – what to do?
Most common cause: wrong quilt version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.19.2). You can switch loaders with one click in the panel.
Is Aptitude compatible with quilt?
Aptitude officially supports quilt for Minecraft 1.19.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Aptitude – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Aptitude consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
