My wishlist for Scarred Lands
4e...
An updated campaign book would be nice, maybe advancing the timeline a little bit. I still love the Gelspad Campaign guide and think it would be hard to top, but even a rewrite of that with just a couple new things would still be something I'd buy.
For crunch
necromancy powers for players
True rituals
Tattoo magic
A paragon path for vigilants.
Stats for Dar'Tan and the penumbral pentagon.
Invocation feats for the clerics of Scarred Lands gods.
Rules for making charduni and SL dark elves (maybe with golem parts?)
A new adventure that would be a follow up to The Serpent Amphora Cycle. This would be doubly awesome if it gave a reveal of what the Autumn Kings ultimate goals were.
An adventure that centers around Hollowfaust would be cool!
An adventure that takes place in Blood Bayou.
A really nice big map would be something I'd get. I'd have to use my enchantment powers on the wife to let me hang it up on the wall, but I'd do it.
