I'm going to try a little experiment here. I'm looking for links to OSR-gaming-related blog posts (including links to downloads) of material related to undead. It could be new classes, combat rules, magic items, free adventures, reviews, new monsters, etc. Please, no links to actual commercial products, though PWYW items are considered.
I would prefer if the entire content at the link is undead-related (as opposed to say just 25% of what's at the post), but all input will be considered.
For example, here's a few from my own blog over the last few years:
How to Embalm a Corpse
Optional Rules for Killing a Vampire
Tomb of Ludor the Beheader (one-page adventure)
New Monster: Flailing Spirit
New Monster: Bestial Beast
If there is something undead-related as part of a larger post, then call it out. For example...
At this link, there is a spell called "Animate Warrior" (animates warrior zombies)
Before the link, it would help if there's a description. E.g.,
FREE 1-PAGE ADVENTURE: TOMB OF LUDOR THE BEHEADER
Okay. Let 'er rip!
