Animal Friends for Everyone

World building idea blatantly stolen from The Hobbit:

Every in-game race has an ancient alliance with a particular race of wild animals- a species of bird, for instance. Members of this race can automatically communicate with that species or type of animal. Animals of that type are not necessarily the companion or servant of that particular race, they just are cordial with one another and will help each other out if the opportunity presents itself and it isn't too inconvenient. Animals of that type will generally not attack members of their 'ally' race unless the animal is sick or starving to death. Animals of the appropriate type can be negotiated with to provide favors, but they are generally the type of favors that are covered by something the animal would already be likely to do.

Example pairings:
Elves - Robins, jays, swans and other similar birds
Gnomes - Burrowing mammals- moles, badgers, groundhogs, marmots, chipmunks
Dwarfs - Eagles; possibly bears
Goblins - Wolves and wargs
Orcs - Carrion crows
Humans - Non-wolf dogs and wild horses; hawks
Halflings - Mice and sparrows

Example Interactions: An elf could ask a blue jay to carry a message to another elf who lives within 1 days flight, or to pass the message on to another blue jay who can pass it on to whoever. A bird is going to be flying around all the damn time anyway, and doesn't need any incentive to pick one place over another. A wolf (who probably spends all day scouting his territory anyway) would tell a goblin when someone new has entered or left the territory he patrols, and what rumors he has heard through night-time howling from other packs. Violent animals might be willing to go along with their allied races in combat, but their goal is slaughter and feeding, not clearly defined strategic objectives. Carrion crows enjoy telling orcs things that will rile them up and get them out killing people because hey, free buffet. More complicated favors (things that involve doing something the animal would not normally do, like carry a rider or a message, fight someone, fly in bad weather would require convincing the same way you would need to convince or bribe a friendly stranger to do something. Particularly animals may become friends with an individual rather than just pleasantly disposed towards a particular race. Hunting or killing a member of your allied animal species gives you a bad reputation and makes it more likely your future requests will be refused.

It also occurs to me that the Alignment languages from the early versions of D&D could be used for this purpose- your ally species speaks the alignment language of your race- Chaotic Good for Elves, Lawful Good for Dwarves, Neutral for Humans, Neutral Good for Halflings, Neutral Evil for Goblins, Chaotic Evil for Orcs, Lawful Evil for hobgoblins, etc.

Taint as an Alternate Paladin Mechanic

Paladins are one of those classes that provoke a disproportionate amount of debate and/or hate. One of the big problems with Paladins is the use of alignment (a mechanic with a long history of pointless argument and other sturm and drang) to balance the extra goodies that Paladins get as a 'holy warrior' class. The need to maintain Lawful Good alignment and use only Good allies and henchmen can become a pain for the whole party; the Paladin player's choice of character ends up limiting what his fellow players can do and what concepts will work within the game. It might be great for high-immersion groups who are primarily interested in telling a good story, but as a game mechanism it's a source of tension and bother without an accompanying upside. If alignment is ignored (as 4e did, and as some DMs irritated by the whole thing certainly did in pre-4e), Paladins end up being rather flavorless- they're just a super-Fighter with magic powers.

The all-or-nothing nature of 'loosing' Paladinhood is also a particularly blunt instrument- either you're in the favor of your God, or you're not. There is no mechanic that reflects 'skating on thin ice' or a gradual descent into naughtyness- you're either one of the Divine Elect or you're a nobody. So here's an alternative:

Taint Points: Paladins start with a Taint score of zero. For every unlawful act they personally commit ('unlawful' in this case meaning out of alignment with the goals and values of the deity they serve), they gain one Taint point.

Taint Points in Play: Whenever a Paladin invokes a class ability, spell, or spell-like ability, roll 1d20. If the result is less than the current Taint score of the Paladin, the attempt to use the ability fails and that ability can not be used again that day until the Paladin has slept and prayed (i.e., the next time he has the opportunity to prepare spells for the day). This applies to casting spells, lay on hands, auras, turning undead, immunities, and other supernatural and spell-like effects, but not to base attack bonus/THAC0, level/attribute determined saving throws, weapon and armor use, etc.

Getting Rid of Taint Points: To get rid of Taint points, the Paladin must complete some action to bring himself back into the favor of his deity. This can include:

• An Atonement spell cast by a cleric at least two levels higher than the Paladin. The cleric will likely require the Paladin to complete some task (possible a Quest/Geas) to earn the spell, but not one as complex as the quest option described below. The cleric may also require a donation to his or her temple.
• Tithing 5% of the Paladin's current wealth to an appropriate temple. The donation can be cash or equivalent magic items/treasure. The donation must be for the use of the temple- the player/character can not, for example, donate treasure to a temple that is part of their own fortress or castle or donate to a temple that they are in control of. If you ordinarily give XP for class-appropriate treasure spending, the character receives no XP for this donation.
• Undertaking a major quest for the appropriate deity or temple, for which the character receives no XP and donates all recovered treasure to the temple, might be worth wiping a Taint score back to zero.
• Laboring under a vow for an appropriate amount of time. A god of war might want you to refuse using missile weapons for five combats. A god that protects the poor might want you to give generously to anyone who asks for money or other help for a month. Any god might accept fighting without magical weapons or armor for an appropriate number of combats or using crude and simple weapons (possibly ones that you are not proficient in) like daggers and clubs.
