Alternity Combat Tracker

This is a simple combat tracker I designed for Alternity. My suggestion is to give each PC and NPC some kind of token for each action they get in a round, then simply place them in the box labeled with the appropriate action check result. Should provide an easy way to keep track of combat without a lot of scrap paper.

This document contains notes on the mechanics of converting Call of Cthulhu 5th edition materials to Alternity. Rules design by Jim Clunie, Word design and formatting by Charles Borges.

This is a tool for GMs and not a complete game. Use of this conversion requires access to the fear, horror and madness check rules in James Wyatt's article "No One Can Hear You Scream" from Dragon #258. The Call of Cthulhu 5th Edition rulebook would be helpful.

This update converts the resource to PDF, adds several spell conversions, additional spell statistics, the term "correlation check" and various clarifications.

d20 to Alternity Conversion

These notes convert core d20 (based on the d20 SRD and d20 Modern SRD) to core Alternity (based on the Players' Handbook and Game Master's Guide, plus Beyond Science). No other supplements, and a bare minimum of additional or homebrewed Alternity rules are proposed for use. I've combined Parts 1, 2 and some notes on specific d20 systems and converted the document to PDF.
