It’s not possible to play the Battle Imps any more (due leave a comment if you think its worth re-creating though). The original game simply randomly awarded you an imp with stats randomly generated between 1 and 10.
Imps battled by rolling a d10 and adding that to a current stat. The imp which won the most stat-to-stat totals won the battle.
Just in case you fancy creating your own game of Battle Imp head-to-head I’ve suggested TT style values for the imps.
