Ok, first: announcement: So James Raggi had me rewrite his classic Death Frost Doom module (the one I started my own campaign off with) to create a new deluxe version with more new stuff in it (and less old stuff) with Jez Gordon ilustrations. I feel good about it "…this feels like the essence of D&D crushed into diamond. Overworld and Underworld. Pure myth. "
It is currently available as part of the Bundle of Holding charity thing, where you can get this along with the Labyrinth Lord Advanced, and +Dyson Logos 's Dyson's Delves (awesome maps) and much more--all together for like 8 bucks or whatever. Only available for a week.
If you have any questions about what the differences between the old and new Death Frost Dooms feel free to ask in the comments--I definitely think the rewrite is worth getting even if you have the old one, as there's a lot of new content you can scrape fro other dungeons.
continuing to vandalize the 5e monster manual.
Behirs. Behirs are basically crappy semidragons as if D&D needed more of those dating back to AD&D Monster Manual 2. However, the new 5e illustration is very cool and salamandery, and I did was black-in the shadow to make it look nice and slimy.
I completely, if lazily, overhauled this monster:
"Behir" is a nice, pseudo-Arabic Jack Vance-style name--so I figured chaos wizards of the Dying Earth thousands of years into the future send Behirs back in time to whisper spells into the ears of sorcerers while they sleep.
The Chaos Wizards hope to place the right spells with the right wizards at the right time in order to carefully manipulate timelines so that futures where they rule come about.
Since these effects are subtle and have a butterfly-wing-theory-like effect on the future, practically speaking it seems like the wizard's just getting random spells each night. Which, in game terms, they are.
This very speedy revision of the Behir is based on two way better ideas you should read:
1. False Patrick's Shaman class-which chases spells in dreams using a cool mechanic which you can totally port over if a PC gets hold of a Behir.
2. Arnold Punch's idea about where faeries come from.
