The opening post will contain houserules and rule clarifications/interpretations. Any changes prompted by subsequent posts will be reflected in the opening post.
Critical Strike Bonus Damage
Only attacks that deal damage, which can be either constant or variable (i.e., the result of a die roll), may receive the critical strike bonus effect (usually dice) from their weapon/implement on a critical hit.
To reuse an example from the PHB2: a wizard who rolls a natural 20 when casting Sleep does not roll any crit. bonus dice from his implement because Sleep does not do any damage.
Daily Power Regeneration
Upon attaining a milestone, you may regain the use of an expended daily power provided that its use has not been regained since the last extended rest. If no daily powers are elligible to be regained, or if you choose not to regain a daily power at this time, this opportunity is lost.
Knowledge Checks
Knowledge checks use the level-appropriate easy/medium/hard skill DCs + 5 for common, expert, and master knowledge. At level 1, for example, the DCs for common, expert, and master knowledge would be 10, 15, and 20 respectively.
Supplies
Please make sure you have enough supplies for your expeditions. It would be embarassing if everyone starved to death. If everyone takes an adventurer's kit, they have 10 days worth of rations. Don't forget to buy more!
Weapon/Implement Expertise
At levels 5, 15, and 25, you receives a +1 bonus to attack rolls as if you had taken the appropriate expertise feats. This obsoletes the weapon and implement expertise feats, making them unavailable.
