Old School Deep One Race-as-Class

This is just a common-or-garden Deep One class; it's just keeping company with the Ghoul, the Shoggoth and the Yithian.

It's not the one I came up with for a specific setting - that requires checking more than one unindexed notebook, which will also hopefully turn up the Wilbur Whateley-type ("I wonder how I shall look when the earth is cleared and there are no earth beings on it").

Deep One.

Description: Scaly, batrachian, ichthyic, with bulging eyes and webbed claws. 

Some people find this attractive.

XP: Advance using the Dwarf Experience Table; same level limit applies.

Saving Throws: Save as a Dwarf/ Monster of your Level/HD, whichever is better.

Prime Requisite: The Deep One class has no Prime Requisite.

Minimum Scores: No minimum scores, but your Dexterity on land is d6+2, while your Dexterity in the water is d6+12. 

Hit Dice: d8, or whatever is the standard for monsters in your game. You have 2 HD at 1st level.

Armour: Deep Ones have natural armour that improves AC by 2 places; Dexterity adjustments apply. You will not wear armour, even if it could be made to fit. You can use a shield. 

Weapons: You can use any weapon (something suitably aquatic/nautical), but can make one claw or one bite attack for 1-6 damage instead.

Special Abilities:

• You can breathe, speak and cast spells underwater.
• You can swim at a rate of 18.
• You cannot be surprised underwater.
• You save at +4 vs. water-based attacks/spells.
• You can cast spells from scrolls (Cleric or Magic User) with a 10% chance of failure, but land-lubber scrolls won't survive submerging.
