Also new for 3 rd Edition are Feats. Feats cover a plethora of special abilities that characters can gain. Characters get one feat at first level, one at third and then one ever three levels thereafter. Humans also get a bonus feat at first level. Finally, fighters and wizards get bonus class-related feats that must be chosen from special lists.
Some feats also have prerequisites.
For example, a character must be a Fighter, at least 4 th level and have previously taken Weapon Focus, in order to take Weapon Specialization. Religion is given brief treatment and nineteen Greyhawk deities are presented for characters to worship or for DMs to use as models for their own campaigns. Two tables divide up the deities by the race and class of their worshippers. Everything from attacks of opportunity to the way armor class works now is new and different. You should definitely give Combat at least a couple of readings before trying to run your first game.
