"Yes, so we've got strength, dexterity, constitution for physical traits, which will matter in hand to hand combat." Al counted them off on his fingers. "Add to that the mental traits of intelligence, charisma, and wisdom." He tilted his head. "The mental abilities will affect the spellcasting quite a bit but a mage should probably stay away from direct hits with a hammer. Oh, and if they're a cleric they can cast healing spells and raise shields - hey, I know, Lorcan would make a perfect healer! - andandand, wait, there's also special powers. And alignment factors, good versus evil, lawful versus chaotic, which will affect the character decisions... "
Al perched in his chair like an owl, also trying to take over half of Peter's seating space, in his attempt to poke his nose further into the book over Peter's shoulder.
"We'll need at least three characters in an adventuring party and a Dungeon Master to oversee the map, and the monsters, I can do that, by the way, since I've got sufficient practice keeping track of the rules, and - Oh! this is going to be brilliant!" Al beamed at Peter with a smile strangely resembling one of an evil genius.
