3rd Edition Dungeons & Dragons: Monster Manual IV
Zack: Monster Manual IV contains, literally, 35+ pages of Tiamat. These things are the worst.aspect of that filler affront: the colorspawns.
Steve: Some of them are cool!
Zack: Yeah, some of them ARE cool, because they're complete retreads with new names and some stupid association with Tiamat, the giant devil dragon that rules over dragon hell or whatever.Steve: Each of the heads of Tiamat has a different outcome on the spawn, so white dragon head results in white lizard looking babies.
Zack: This for 35 pages. Mind-numbing repetition of greenspan and darkspawn and whitespawn. It's enough to make you want to quit playing D&D.
Steve: Nothing could get me to quit that.
