Current House Rules

Fumbles

- a fumble occurs when a monster or character rolls a natural 1 on its first attack roll of the turn. A fumble can be handled on-the-fly by the DM or the DM can consult the chart below.
(d6 or more severe d10)
1: drops weapon 1d10 spaces away
2: injuries self, rolls damage for current weapon as though a successful hit
3: slips and falls, suffering 1d6 damage; opponent gets an attack of opportunity
4: overswings; opponent gets an attack of opportunity
5: armor comes uncoupled, reducing AC by 2 and tripping up current attack
6: slips and turns to face opposite direction; opponent gets an attack of opportunity
7*: weapon breaks
8*: bonks head, is stunned 1d2 rounds; opponent gets an attack of opportunity
9*: weapon flies out of hand, strikes ally (roll damage regularly without strength)
10*: something terrible
Specific Weapon Fumbles
* blow/dart gun: wielder sucks dart into his mouth, dealing damage as normal and incapacitating user for 1d4 rounds.
* bow: bow string snaps requiring 1d4 rounds to replace. This time is reduced to 1d2 rounds if user has any archery-related feats.

Dying

A character dies when his or her hit point drop to the negative of his or her constitution score. For example: Talia's constitution score is 15. She takes damage bringing her to - 3 hit points. If she is not healed or stabilized, she will die in 13 round when she reaches -16 points.

Action Points

each player receives 3 action points per session. Used action points are given to the DM and may be used for enemies' rolls.

Instant Death

Three 20s in a row on a critical hit means an instant kill, subject to the DM's discretion.

Feat Purchasing
I have a house rule, adopted from I-forget-where, allowing PCs (and important NPCs) to buy feats. The first feat you buy costs 500exp, the second costs an additional 1000, and the third costs another 1500. You may buy a maximum of three feats. Buying all three costs 3000exp, and you may only buy one feat per level. Also, you may not spend exp if it would put you below your current level.

Replacing PCs
Another possibly important house rule: if you die and roll a new character, the new character starts 1 level lower than the average party level, with exp half-way to the next level (if the PC's are very close to the next level, then the new PC starts with exp at 3/4 of the current level). Starting equipment will be determined at the time.
