TSR House Rules

This post will be updated with house rules I am using for Tales of the Splintered Realm. Use or don't use as you see fit:

Gameplay Rules

• Automatic damage effects (like the heat from a fire ant) are capped at 2 points per round; if four fire ants surround a character, that character does not suffer 4 hp damage per round.
• In melee combat, no more than 3 creatures of the same size can engage you at once. No more than 2 creatures of any size larger, and no more than 4 creatures of any size smaller. A normal human could be attacked in melee by up to 4 rats, 3 gargoyles, or 2 ogres at once. This would limit sundering to only affecting those total targets as well. I found this was necessary to keep my solo stoutling defender alive; when he took on 7 rats, he was going to be killed quickly if not for the quick application of this rule :) This will also keep him alive later on, when he's taking on many undead at once.
• For solo play, I am ruling that drinking a potion counts as a minor action, allowing one attack at -2 (because my character is going through healing potions like CRAZY to stay alive).

Purchasing Scrolls

The rules state that scrolls must be found on adventures. I rule that scrolls may be purchased in some places. A small country shrine may carry tier 1 scrolls, while the temple in a major city may stock scrolls of up to tier 3; you would have to journey to the Library at Asgoth's Summit to find a scroll of Tier 5.

Tier 1: 100 sp

Tier 2: 250 sp

Tier 3: 500 sp

Tier 4: 1,000 sp

Tier 5: 2,500 sp

Tier 6: 5,000 sp

Purchasing Weapons or Armor

The rules have no mechanism for purchasing magical weapons and armor. Larger merchants may have gained some through barter. The standard prices are:

+1 weapons or armor are the base cost in gold +100 gp.  (A +1 medium weapon would cost around 115 gp, or 1150 sp; a suit of +1 plate mail armor would likely go for around 400 gp, or 4,000 sp). The more powerful an item, the less likely it is that a merchant will carry it.

+2 weapons or armor are the base cost in gold x10, +250 gp. (A +2 short bow would cost around 500 gp, or 5,000 sp; a suit of +2 chainmail armor would cost around 1,000 gp, or 10,000 sp). Very few merchants would stock such items.

Purchasing Potions

Larger alchemical shops are going to stock some basic potions. Most potions sell for around 100 sp, but more potent elixirs may sell for upwards of 500 sp.

Selling Items

Use the prices above to sell items to vendors; you get 50% of the value in any item you sell back (including mundane items you purchase; when you upgrade your studded leather armor to chainmail, you get 10 sp credit from the studded leather towards the new price)
