[QUOTE="billd91, post: 3434177, member: 3400"] A DM I played 1st edition with used the crit charts from MERP. I know we used the crush, slash, and piercing crit charts (I can't remember about spells) and a crit occurred when someone rolled a natural 20 or hit by at least 5 points. He used the additional damage numbers straight off the table because they're reasonably compatible between D&D and MERP. But he also modified the die roll on the table. Characters wearing armor subtracted 5% per step on the armor table. So platemail (AC 3 in 1st edition, 7 steps better on the table compared to no armor) was a -35% on the critical roll. Bracers of Defense, not actually being armor, got you no reduction, so there was a benefit to having and wearing heavy armor. I can't remember what he added to the roll to send the roll over 100. There was something but I don't remember what it was. I don't believe he used the A-E critical rating as listed in MERP. [/QUOTE]
