Inherent Enhancement Bonuses: Magic items are more rare and difficult to create, so we’ll be using the inherent enhancement bonuses system from the DMG2. Basically, you’ll get an automatic +1 enhancement bonus to attack and damage rolls at 2nd level, an automatic +1 enhancement bonus to defenses at 4th level, then those will increase every 5 levels (so you’ll get +2 to attack and damage at 7th level and +2 to defenses at 9th level).
Extended Rests/Adventure Rests: I can explain this more in person, but I have a different system of resting than the basic PHB extended rests. The regular system is balanced for a dungeon crawl where you’ll face four or five encounters in between extended rests, but this game will be more narrative with more time between encounters. So, daily powers won’t be based off of extended rests, and will instead be based off of milestones (beating encounters, usually every 2 encounters, just like action points). You’ll regain one daily power for each milestone. Healing surges are still based on extended rests, but you regain only half your surges per rest.
There’s a new category of rest called an adventure rest, this is a several day period where your characters take time to relax and refresh themselves, usually at the end of an adventure. This is where everything returns to full, and is usually when you will level as well.
