I've made more progress in listing my free games on DrivethruRPG/RPGNow with all five Microlite74 Companion volumes now available for download as "Pay What You Want" games (and free is a perfectly acceptable amount to pay).

This volume includes any classic treasure items as well as a few new items designed for the Microlite74 system.

Microlite74 Companion V: First Edition Spells -- This volume provides more detailed descriptions of spells and provides many new spells similar to those in the first edition of the world’s most popular fantasy RPG. Using the spells in this companion volume instead of the ones in the Microlite74 Standard or Extended rules will make your game more similar the First Edition (1e) than the Original Edition (0e), especially when combined with monsters from Microlite74 Companion IV: Bestiary of Monsters. Most of these spells are suitable for use with either the Standard, or Extended versions of Microlite74. With care some can be used with the Basic version of Microlite74. Healing spells list alternative effects for the Basic/Standard HP system and for the Extended HP/BP system.
