About this mod

Small mod that lets the player and NPCs block incoming maleffects when successfully blocking with a shield/weapon or ward spell. Updated from LE with fixes and addons. No more "spider-spit CTD."

NOTE BEFORE INSTALLING: Read on, or skip and scroll to the bottom of the page for requirements and compatibility notes.

We've all been there...
You're waltzing through an old ruin or cave, and suddenly find yourself face-to-mandibles with some type of giant creepy-crawly, or perhaps one of the Falmer with their poison-coated weapons. They attack, and you lift your shield in reaction on the perfectly logical assumption that inches of hardened metal, hide, wood, or a magically generated barrier will protect you from harm...

The venom teleports through any obstacle, and immediately starts eating away at your health! You're forced to battle with your health unjustly compromised, and no way to defend yourself from another similar attack! 

And the lack of sense doesn't stop there; 
The next thing you know, a Skeever rams its face into your shield and OH NO!
You've got Ataxia
Um, what?

Thus, I share with you:

Paulicus's Oldrim mod, Shields Block Poison, strives to solve these "problems" (or signs of laziness/weird choices/design flaws/whatever you want to call them) and many other similar scenarios. Thus, it has been a godsend to me for years.

However, after noticing that the latest SSE port of Paulicus's mod was outdated (based on version 1.4.1), I decided to port the updated version (version 1.6), as well as fix the remaining issues and complete its features. I'm sharing it since others expressed an interest.

Original Mod Description by Paulicus:
(With slight revision for the sake of relevance, and additions from Paulicus's changelogs)

I didn't like that Skyrim's Poison Effect would still work against a blocking opponent, so I made this tiny mod to fix it. 
Despite the title, 
it works both with and without shields.

  • Version 1.6: Added conditions to allow wards to block poison and disease effects as well.
  1. I made the angle conditions wider for wards, similar to blocking spit attacks, because the ward seems to cover a larger area than most shields. Wards cover 360 degrees with spit attacks (native Skyrim functionality; I didn't have to edit any spit effects, just melee ones). With this mod, wards will block melee attacks in an area about 160 degrees in front of the player.
  • Version 1.5: I fixed the conditions so all issues with NPCs and directional facing should be gone
  1. Blocking poisons should work as intended in all scenarios now.

This is the "Full Version" of the Mod:

This mod is just a few simple edits to magic effect (MGEF) records in TES5Edit to check if the target is blocking when a poison effect is applied. Despite the title, it works both with and without shields (though you'll need a shield to block spit attacks). It also affects NPCs in addition to the player.

I added "GetRelativeAngle" conditions to poison effects to match the blocking area in front of the player. This means that you will no longer be negating poisons unless you actually block the hit! Activating block will not remove or affect ongoing poisons, the conditions are only checked when the poison is initially applied.

I made this by editing the magic effect records (MGEF) in TES5Edit to add a few conditions to all poison effects. Very simple. This does mean that any mod that also edits those records will be incompatible, and need a patch. The only mod in my list of 100+ that edits those records is Requiem, though there could be others. Also, some mods may also create new MGEF records of their own. In that case, this mod would not affect those poisons, though they wouldn't directly conflict. Hunterborn is the only mod I use that does this, but other creature mods might as well.

I believe that I found all the relevant MGEF records, but it's possible that I've missed some.

NOTE: Since version 1.3 of the mod, the issue where some users would get CTDs randomly upon spider attacks has mostly been resolved. [Zira's note: with this SE version, PPB Updated, this is now 100% resolved.]

If you want to tweak this mod or make your own patch, it's extremely simple to do in TES5Edit. As of version 1.5, I've learned how to set the conditions so that they are evaluated dynamically between subject and target. This means that previous disclaimers about unexpected behaviors in NPC vs NPC combat are void. The mod now properly evaluates blocking and facing conditions in all cases.

Paulicus Poison Block (PPB) Updated

Paulicus: "Feel free to reuse this mod however you like. Make patches, translations, include it in your mod, all okay. Just be sure you credit me. You may not use this mod in any for-profit, commercial, or paid-mod-related service."
Paulicus: "I haven't played Skyrim in some time, so probably [no SSE Port] in any timely manner. [...] That said, I don't mind if anyone wants to port/remake it and post it."

As for what I have added or changed about the mod going off of Paulicus's work and the suggestions of others, PPB Updated includes:

  • A guaranteed fix for the infamous "spider-spit CTD," courtesy of Jazzkiwifruit's advice.
  • Patches for all the popular SE alchemy mods as well as Requiem SE.
  • Conditions for melee poison in addition to projectile poison, courtesy of Camillo82's advice, and CovenantTurtle's assistance.
  • Fleshed out the included creatures/poisons, with the additions of the Afflicted, Venomfang Skeevers, and the Chaurus variants added by the Dawnguard DLC. If you find any other oversights not yet covered, feel free to lmk in the comments.

If you find any further issues, or have any recommendations, advice, or requests, please leave a comment. I am still relatively new to understanding how best to employ these conditions.

I hope you enjoy the mod.
And please toss Paulicus's LE mod an endorsement if you do.


Patches for the following mods are available during installation (FOMOD):
Complete Alchemy and Cooking Overhaul

This Mod's Requirements:
Unofficial Skyrim Special Edition Patch


This mod should be safe to install and uninstall at any point. Just download, install, and activate the plugin/s with your chosen mod manager.

Load Order:
  1. USSEP - Unofficial Skyrim Special Edition Patch 
  2. Other Mods affecting the same vanilla MGEF and SPELL records
  3. PPB - Paulicus Poison Block
  4. Patches for PPB and those Other Mods


Simply uninstall/disable/deactivate/delete the mod/plugin with your manager.


  • Any mod that affects the same records will require a patch to merge and forward PPB's changes. The only mods that are likely to conflict are mods affecting alchemy poison effects, mods affecting ward functionalities, and mods that change the effects of the enemies involved.
  • Mods that add new poison effects, new relevant spells, or new creatures with their own unique poison attacks will require a patch that adds PPB's changes to those effects if you want them to be blocked through this mod. 
  • This mod is still safe to use even alongside mods which conflict in one of the above two ways, but depending on load order, its effects may be overwritten or inconsistent.
  • Patches/Alternate Versions are currently available for the following mods:
          -  Requiem - The Roleplaying Overhaul
          -  Complete Alchemy and Cooking Overhaul
          -  Apothecary - An Alchemy Overhaul
