kcw | battletech campaign | ad&d conversion notes
<< Previous Page | Next Page >>
These notes are intended to be used for running BattleMechs in an AD&D "dungeon-crawl" type of module. The tables are for converting monsters to BattleTech values. I assume that the monsters and dungeon are 'Mech- sized. I don't deal with treasure, XP, or spells.

Damage, Hit Points

Damage Points convert 1:1
Hit Points convert 1:1
