I’ve written up a ton of hacks and house rules, and I’ve been given some thought to what house rules I would use if I could use any I like. (Alas, I have to take players’ tolerances into account)
This is similar to the system for rest used in Adventures in Middle-Earth. Long rest is only available when in civilization, or at least resting someplace safe and comfortable. Ever gotten great sleep on the ground out in the weather? Yeah, me neither.
I also like the system whereby during a long rest, rather than recovering all of your hit points automatically, you are able to roll all of your remaining hit dice to recover hit points. This will recover a lot of hit points, but not necessarily all.
Half of my players can’t even be bothered to track their own coinage (my wife in particular) and I never particularly enjoy making sure every monster they defeat erupts into the correct amount of coinage when they die. Instead, I’d like to just use rolls against set difficulties, using the character’s proficiency bonus. If the character is flush with cash, say just back from a dungeon delve, then they roll with advantage. When they are in debt or broke according to the fiction, they roll with disadvantage. Since my players love to haggle, successful haggling doubles your proficiency bonus for the roll, while failed haggling makes you just roll a straight d20.
When you want to buy something, here are the DCs:
- Something simple and inexpensive, like adventuring gear: DC 8
- Something mundane but expensive, or a common magic item, like a longbow or a healing potion: DC 10
- Something very expensive, like plate armor, or an uncommon magic item: DC 12
- A rare magic item: DC 15
- A very rare magic item: DC 18
- A legendary magic item: DC 20
Of course, PCs have to put in the work finding rare or expensive (or magical) items before they can make the roll to see if they can afford them. The DM has an option of saying that a character who fails the roll still buys the item, but is strapped for cash. Most of the time, when returning from an adventure, the characters will be flush with cash, and that’ll be the time they want to buy things anyway. So a mid-level character (level 9+) returning from an adventure will have just shy of a 50/50 chance of affording a legendary magic item, and better than 50/50 of affording a very rare magic item. The limitation there will be based on the setting, with this being plausible in Eberron and less likely in another setting, based on availability of magic items overall.
I think that the payoff of using historical firearms, rather than a weapon like a longbow, is that it as a slower rate of fire and does a lot more damage. At least, that’s what I’d like to house-rule firearms to do. So as a house rule, I have black powder pistols require two rounds to reload, and black powder rifles require three, and their damage dice are doubled.
10th Level Spells
10th level spells exist, and as one would expect they are available through scrolls (which are of course artifacts) and for 19th level spellcasters. Such spells can be world-changing, but can only be cast once each by a given spellcaster.
When a player selects a background, they should also flesh out the background with all of the NPCs who might be connected, including their immediate family, rivals, mentors and the like. As a rule of thumb, at least a couple of interesting NPCs who might get caught up in the story per background.
I like using alignment, but alignment as written in D&D includes a lot of nonsense and argument-fodder. So what I do is I replace “Good” with another descriptor that defines what “good” will mean in this setting. For example, in my Twilight of the Gods setting, good becomes “Generous.” I replace “Lawful” with an order-oriented, pro-social term from the setting that is morally neutral if possible. In Twilight of the Gods, that becomes “Civilized.” I replace “Chaotic” with a pro-freedom, or maybe individualistic, term; in Twilight of the Gods, that term is “Wild.” And then for “Evil” I do the same as I did for “Good” – choose a more specific or helpful term. In Twilight of the Gods, that term is “Treacherous.” So instead of Chaotic Evil, a character would be Wild and Treacherous. Instead of Lawful Good, a character would be Generous and Civilized. See? Better. Also, a result of this is that “evil” characters are much more viable. One can play a “Selfish” character in Twilight of the Gods more easily than an “Evil” character in a standard D&D setting.
Discount Adventuring Gear
In a game that is using currency, this is just an option to buy adventuring gear at a 50% discount. The associated cost is that with any failed roll, and almost certainly on a roll of “1”, the gear breaks, and can probably only be repaired with the appropriate tool proficiency.
With the above system of going cash-less, maybe a failed roll allows a PC to buy a discount version of what they wanted. So they get what they were after…kind of.
Simplified Paralysis Effect
For any effect that paralyzes, such as hold person or a ghast’s claws, a paralyzed character is shaken free of paralysis the first time an automatic critical hit is scored against them.
…Or Resist Paralysis at Cost
As another option for PCs who are paralyzed, they can choose to take 10 psychic damage for each level of the spell used to paralyze them (or an amount the DM thinks is appropriate for monster abilites that aren’t spells) in order to take an action to break free. So they still lose at least one action, and take the damage, but aren’t standing there doing nothing for round after round. Probably need a house rule that for species that are resistant to psychic damage, like kalashtar, they need to take the full damage to break free. Their resistance doesn’t help them in this one instance.
Bards have never really gained a bonus, or any kind of benefit, for using their musical instrument in combat. I like the idea of a bard being able to use their abilities more effectively if they focus on their music alone (much like bards in Everquest, honestly). I would want to work out specifics with the bard player, assuming they were interested, but here are the options I’d have in mind:
- The bard counts as two levels higher than normal, and has access to more powerful spells
- The bard’s spells are power potent, adding 1 or 2 to their spell attack bonus and to the DC for saves against their magic
- They don’t lose spell slots – they can keep casting indefinitely, or maybe they have one extra spell slot per level that can only be used when they are using their instrument in combat (since indefinite spells is pretty powerful)
- There is an ongoing bonus effect – an aura of courage like a paladin has, or an aura of bonus hit points for her comrades, or something similar
- Her other bardic inspiration dice go up one die type, so from d6 to d8 and so on
The heading is a link to the full table that I posted a while back, but for theater of the mind I like a system where you roll randomly to see how many creatures are caught in an area of effect spell. Just assume that the character is doing all they can to maximize the spell’s effectiveness and avoid hitting their friends. I would have to adjust this system for an evocation specialist wizard who could sculpt their spells to hit their foes and avoid their friends, but that’s easy enough to hand-wave (add a bonus to the AoE roll or something).
