A downloadable OSR addon

Buy Now$4.00 USD or more

This system is designed to be plugged into any OSR game that uses dice of various sizes for weapons. The goals of this system are:

Give players reason to pick weapons that have smaller damage dice, to expand their options

Give players rolling low damage a boost as a form of comeback mechanic

Add tactical depth to combat

Any time a player rolls a 1 on a damage roll, they inflict damage (1+modifiers) and choose one of the listed effects to activate.

If a player is unhappy with their damage roll, they can spend 1 Control to either reroll the damage dice or set it to 1. Control is a weapon stat and resets every encounter/combat.

This is actually great. 5/5 stars.


This is dope. I will be integrating it into OSR games that I run going forward. And I'm looking forward to your expansions!


I’m going to be expanding this idea as I get new input. Things I’m working on are:

  • Weapon Switching during combat (basically spent Control is deducted from any weapon you switch to)
  • Magical Spells as Weapons
  • Ranged Weapons make -1 Control, but requiring Ammo gives +1 Control
  • Additional Damage Dice cost 2 Control

Tell me what you need to make this work!
