Well, coming from other PPM "system specific" solo tools and Mythic Game Master Emulator, this supplement DOES NOT provide Harn, Rolemaster, or High Adventure specific tips other than using d100 oracle that looks similar to Ironsworn.

What I want this supplement to provide is system specific tools and tricks to make Rolemaster, Harn or High Adventure to solo like monster creation and making combat easier like Scarlet Heroes does by using Hit Dice as Wounds.

Ruinous Explorations "for Worlds Without Number" has the Drama Dice timer. Basic Solo Roleplaying has the d% timer, and Old-School Solo has simple tables that easy to build with play examples.
