House Rules
- Healing:
Healing is too slow for an adventure focused game, and it is strange that wounds do not heal at all without total bed rest. Instead, a full nights rest grants an HT roll to recover 1 HP as normal, and a full day of bed rest grants a second one. Bonuses from a physician still apply, and they make their rolls at the normal rate.

- Character Replacements
A player who dies or retires unexpectedly returns with a character with 50% of the character points of the previous one. Instead of suffering this setback in power, a player may instead decide on a replacement before hand, and spend either time or points training them. These replacements may be taken as an ally and trained, at half cost if they are only an ally for training purposes, or given 1CP for every 4CP you wish to raise their capabilities by. Full details are listed on the character creation page: Character Creation Rules.

- Limited Word Magic
Spells with a duration longer than 3 minutes lock out the FP used to cast the spell until the effect ends. Improvised spells are limited to effects that last 3 minutes or less, and cannot be used to conduct any form of divination magic. Divination magic is defined as any spell that provides information from a distant source or time. Mind reading is not divination.

Single target damage spells are limited to 2d6+3 basic damage. Area spells are limited to 2d6+1. No signature is limited to non-damaging spells.

- Harmonized Severe Bleeding
Bleeding as written in the basic set has several problems. It fails to differentiate between multiple small wounds and one large one, making it impossible to stop the bleeding from a thousand individual paper cuts. Bleeding damage is not scaled to the targets HP, so a 300HP dragon may bleed at -50 to their HT roll, but only lose 1 HP a minute and eventually succeed on a critical. These rules change the penalty to first aid and HT rolls into a bonus to bleeding damage, and have first aid and HT reduce the bleeding damage slowly over time.

- Modified Link Version

Link (Single Projectile) +20%
You can use two or more abilities together as long as they have identical Malf, 1/2D, Max, Acc, ROF, Shots, and Recoil. This attack represents a single indivisible unit, and all linked abilities use the same attack roll. On a hit, divide the targets DR by the number of total dice and resolve each hit against the divided DR*dice of damage rounded up. If the target has DR that would apply only to one damage type, divide it between valid damages only.

For example a linked attack that does 1d of burning, 2d of cutting, 2d of crushing, and 1d of toxic hits 7DR. The attack is resolved as 4 separate damage rolls:

1d burning vs 2DR,
2d cutting vs 3DR,
2d crushing vs 3DR,
1d toxic vs 2DR.

- Realistic Helmets
By default GURPS has very generous rules about attacking the eyes and avoiding all possible DR. In reality helmets were often constructed so that only the smallest blades or projectiles could slip through. We will be using a more realistic approach detailed here: Realistic Helmets

- Revised Weapon Parry and Breakage
By default GURPS weapon breakage rules while parrying leave much to be desired. We will be using a more practical approach detailed here: Revised Weapon Breakage

- Realistic Falling Damage
Armour effective at preventing falling damage, to the point of chain mail rendering twenty or thirty foot drops a non-issue. Base damage for falling onto a soft surface is now always rolled and taken directly as injury. If falling onto a hard surface this damage is rolled again, but this time armour is applied. When falling onto spikes or serrations, if your armour DR is higher than the falling damage the damage is crushing instead of impaling or cutting (edge protection also applies to cutting damage). Additionally, all rolls for damage now have a bonus equal to your level of encumbrance. Falling Damage Only is a -60% modifier.

- Parrying Blade Damage (NO LONGER IN USE):
Parrying with a bladed weapon comes with the risk of damaging the edge, and in extreme cases destroying the blade entirely. Details are provided here: Parrying Blade Damage

- Long Term Magic Healing (NO LONGER IN USE):
The longer a wound is left alone, the more difficult it becomes for a healer to treat it. Healthy tissue merges with damaged, wounds scab instead of healing fully, and so on. All attempts to heal a wound are at a penalty equal to the “Range”, with yards replaced with hours. If two wounds have different ages, the penalty is used for the younger one, and when it is healed the penalty is applied for the older one. If the original roll is still a success, the healing continues, otherwise it is stopped. An hour of study and preparation lowers the penalties by 1, and can be extended using the extra time rules. A successful body reading casting doubles the penalties removed. This never provides a bonus to casting.

- Damage to Armour (NO LONGER IN USE)
Armour that is used and abused in the field slowly deteriorates, and requires repairs and replacement. The rules that follow are based on the 3rd edition pyramid rule here: http://www.sjgames.com/pyramid/sample.html?id=2406. The full rules we are using are detailed here: Damage to Armour
