[Quitti]

Is there any specific ruleset you have thought about using with that RPG? I've been playing out with ideas about dom3 RPG as well, nothing solid yet, but I know at least one other guy who's made pretty big plans already about a campaign in a dominions 3 world.

What I see as a potential problem would be the overpowerdness of magic. Simple chaff simply die in droves when people cast orb lightnings or flame storms or whatnot. And larger foes would simply drop down into petrify/soul slays and so on. That'd mean the magic system would need to be reworked quite a bit to make it "balanced", if it would have to be taken seriously. Or just ban higher level paths from players, make them npc only, making players favor melee characters. Which again would rise up the question about what if the opponent starts using magic.

But about units.
Not cap only: Skratti.
Cap only: Hmm. Helheim/Vanheim dwarves might be fun to play. Haven't played Helheim in ages, but I know at least Van dwarves were cap-only.
Indep: Bloodhenge druid.
