Consequently, the selection of armor for Characters in the Elthos RPG is one of the more interesting choices that players get to make while outfitting for adventures. I like the give and take of the options. And of course, Gamemasters are free to construct any kinds of armors that they think may fit into their worlds. I have some cases where light armors nevertheless absorb a good deal of damage, but those, of course, are quite rare and valuable. I have other armors that are burdensome and don't do such a great job absorbing damage. Their inventors were likely drawn and quartered by the Lords to whom their armors were sold, but the armors persist because ... well, just because. So part of the fun of the game for me is in designing the weapons and armors to have specific effects. And of course, on occasion I toss in magical armors with "impossible" configurations, for good or evil as the case may be. Yup. Fun fun.
In practice, which is to say in my bi-weekly games, we have found that light armors are perfect for some characters who prefer to remain quick and agile, while heavy armor is better suited for others. In either case the Armors as such and the options and variables involved make for a fun tactical combat game. We've been enjoying it this way for some time now at any rate.
I did a little video on the technical aspects of Armor Class usage a while back. Here it is for your interest.
