Dungeon Crawl Classics House Rules

Here's a dump of a bunch of DCC house rules I'd like to use, with some bits of flavor thrown in to imply a vaguely Arthurian setting with bits of Celtic and Norse influence.

Clerics 

Clerics must pick an alignment. Law is the One True Church, which supports the High King. Neutral is one or more pagan gods, nature spirits, or ancestors, still common among common people. Chaos is a forbidden cult or demon worship. 

Healing someone with no alignment works the same as healing someone one alignment step away. Simplifying spells. Critical successes and failures will still be special but I want to reduce charts. 

Warrior

Luck bonus applies to Defense rolls instead of a weapon. Lots of house rules for combat.

Thief

Instead of picking an alignment, pick a Path and get bonuses accordingly. 

Wizard

Simplifying spells. Critical successes and failures will still be special but I want to reduce charts. 

Halfling

Flavor: "Halfling" is a mortal term for any number of small, unassuming fae. Could even be a goblin.

Dwarf

Flavor: If dwarves were ever fae, they left those realms ages ago. 

Elf

Simplifying spells. Flavor-wise, elves are fae creatures with unique supernatural traits. 

1. Horns-antlers or spiral, and small tail
2. Always wears an elaborate hat, must have it to cast spells
3. Plants grow from hair and beard, and from blood spilled on ground
4. Skin is covered in markings like tattoos
5. Eyes are starry fields with no pupils
6. Wild red hair, glowing eyes
7. Rough, dark skin, heavy footsteps
8. Flowing hair, doesn't touch ground when running
9. Hair always wet, excellent swimmer
10. Dresses very old-fashioned, constantly lost in deja-vu
11. Shines brightly in sunlight, gets morose in darkness
12. Gets more lively and slightly taller closer to full moon
13. Forked tongue and slit pupils
14. Animal ears, similar animals are never afraid of the elf
15. Looks like a child, but has adult voice
16. Clothes, eyes, hair, and anything they pick up has the same color hue
17. Voice is a whisper that can be heard within shouting range
18. Art the elf makes seems to move from the corner of the eye
19. Anyone looking at the elf thinks they look kind of like a relative
20. Roll twice

Alignment is an optional choice, because its not just an outline for behavior. In a land where the reign of a king determines the vitality of their kingdom, conviction has real implications. 

Law supports the divine right of the Good King to rule the land, supported by the One True Church. Law says that an oath cannot be broken, fealty cannot be ignored, and order brings peace and safety.

(Knights, Lords, loyalists, Clergy)

Neutral respects their ancestors, the spirits of nature, and the fickle pagan gods. Neutral can believe in a lot of things but overall believes mortals are but a small part of a bigger world.

(Druids, berserkers, witches, wildmen)

Chaos just wants to watch the world burn. Chaos flouts the rightful rulers, spits on just laws, and take what they want from those that need it.

(Reavers, cultists, demon-worshippers)

Ability Scores: roll 2d10, Roll 6 times and arrange.

Underdark Rules

Here's how rules for Underdark D&D, from the players' perspective. I'll post more from the DM's perspective soon.

You have three choices, which can be made in any order.
1) Pick an attribute that you excel in.
2) Pick a class.
3) Pick a race.
Then figure out your To-Hit Rolls, Hit Points, Armour Class, weapon damage, and spells.

Attributes

Your character has one High attribute, two if you're human. You get a bonus to some rolls depending on your High Attribute.

Strength (Str) +1 on Melee To-Hit Rolls and Damage Rolls
Intelligence (Int) +1 to Search Rolls and Wizard Spells
Wisdom (Wis) +1 to Saving Throws and Cleric Spells
Dexterity (Dex) +1 to Missile To-Hit Rolls and Armour Class

To-Hit Rolls

Roll 1d20, beat the number for your class/level on the chart. High Strength gives +1 on Melee (hand to hand weapons). High Dexterity gives +1 to Missile (ranged seapons).
This roll assumes a creature with moderate armor on. Attacking a low armor creature gives you a +2 bonus, attacking a high armor creature gives you a -2 penalty.

Weapons

Small Weapons do 1d6 damage. Ex. dagger, shortsword, mace, handaxe. Clerics, Wizards, and Thieves.
Medium Weapons do 1d8 damage. Ex. longsword, battleaxe, flail. Fighters.
Large Weapons do 1d10 damage and negates the reach advantage of large creatures like giants, but you cannot use a shield while wielding the weapon. Ex. spear, great axe, claymore. Fighters.

Hit Points

Roll one die per level (varies by class). Add +1 per level for High Con.

Armour Class

Base is 11.
+1 for High Dex
+2 for Leather Armour (Thieves)
+4 for Chainmail (Clerics and Fighters)
+2 for Shield (Clerics and Fighters, cannot be used with Large Weapons)

Saving Throws

Roll 4+ on D6 to avoid danger. +1 bonus for High Wis. Other High Attributes may give bonuses for specific types of dangers.

Spells

I used the spell list from Microlite74 Basic, one of several D&D retroclones. Use your own spell list from any edition of D&D and adapt on the fly, or make your own.

That's it! There are lots of holes that require heavy DM adjudication, but honestly that's in the spirit of Basic D&D.
