Dungeon Rules: Four Classes

In thinking of streamlined rules to support dungeon play and exploration, I have one last approach. This approach falls into the "race as class" category. If I used it, I would either bolt it onto Swords & Wizardry Core or Blood & Treasure. The four classes:

Human Fighter

• HD: d8
• Armor: All
• Weapons: All
• Skills: A small selection of thief/rogue skills (optional)
• Other: Feats (Optional); Additional attacks per round at higher levels (optional)

Human Mage

• HD: d4
• Armor: None (or light non-metal, optional)
• Weapons: Typical magic-user/wizard
• Skills (Optional): ???
• Other: Spells (maybe include a few lower-level cleric spells, such as Cure Light Wounds)

Dwarf

• HD: d8+1
• Armor: All
• Weapons: All
• Skills: The usual dwarf stuff. Maybe Find/Femove Traps and Open Locks.
• Other: Extra damage with a battleaxe (optional)

Elf

• HD: d6
• Armor: Light
• Weapons: Wide selection
• Skills: Some thief/rogue (Move Silently and Hide In Shadows, optional); Tracking (optional); Short/low bow specialization (optional)
• Other: Spells (as per Druid or Ranger, or combination)
