3. Skills- I decided not to implement a skill system. Characters will have skills logical to their class; a cleric will have knowledge about his own religion, and about demons and undead. A thief will know where best to gather information in a city. A druid can tell you what plants are safe to eat, etc.
4. Clerics- Clerics are the only human characters to have an Alignment tongue. These secret languages are used to inscribe cleric scrolls, write secret church documents, etc.
5. Elves- Elves have a deeper understanding of the nature of magic than humans do. As such, elves do not need to prepare/memorize spells as human magic-users do. Elves have limited number of spells known (they use the table from Rob Conley's Majestic Wilderness for Wizards), but they do not need to prepare them in advance. They are still limited to a certain number of spells per day, as the channeling of magical energy is mentally exhausting. Elves can teach spells to magic-users and learn spells from them, or from scrolls, or any other source, but they can only learn new spells when their number of spells known increases. Elves typically charge a steep price for their knowledge.
6. Thieves- Are going to stay as-is. They level obscenely fast, so their skills won't stay low for long.
