Rule changes occur periodically between published revisions. The following are recent changes:

Date	Category	Change
May 2010	Skill	Parry: Polearms can now be used to Parry.
Apr 2010	Spell	Enchant Weapon: Increased the damage (lvls 6+).
Feb 2010	Armor	Armor Proficiency: Armor Proficiency and Dodge skills work in conjunction (leather armor only)
Feb 2010	Armor	Armor Skills: Armor skills that require freedom of movement (ie. Dodge and Armor Proficientcy) are affected identically by bound (ie. from Bind, Entangle, etc). The bound location receives no benefit from the Armor Skill. The Armor Skill benefit (for non-bound locations) is reduced by 25% per bound location. For example, a Rogue with Dodge 4 (AC 4) has 1 leg entangled. The Entangled location receives no benefit from Dodge. All other locations have an AC 3 (4 - 25% = 3).
Feb 2010	Spell	Detect Lie: Level 3 Detect Lie has been changed to 1 question. Levels 4 (2 questions) and Level 5 (3 questions) have been added.
Feb 2010	Armor	Dodge Missile: The benefits have been increased.
Feb 2010	Rogue	Use Poison: Changed from "per form" to the standard "per level". As this increases the overall xp cost of the skill, the base cost has be reduced.
Feb 2009	Fighter	Resist Alcohol: Removed.
Feb 2009	Armor	Deflect Object: Removed. The potential for damaging arrows was too great.
