Wulf Ratbane
Adventurer
One thing I might have to try to experiment with will be a super-elite. Limit one per encounter. I was thinking multiply hp by 1 per two characters, and 1 action point per per two characters.
So he's really more of a penult-elite.
Example: Basically, the BBEG would be normally be a solo, but the adventurers have decided to face him in his lair. His two lieutenants, reoccuring villains up till now, would be regular elite. Everything else would be normal.
I think you can accomplish much the same thing just making them all elite-- and then make liberal use of the "Extra Action Point Cause I Say So!" feature if you need it.
Really, the main problem the Solo is trying to address is the economy of actions. If there are enough critters on Team Evil in the room, the problem is not nearly as bad.
One of the things I am considering to "freshen up" the print version is a longer essay-- just an essay-- on Lanchester's Square Law in general. I never got around to working through it for the first release because (a) it's tangential and (b) it requires diagrams to help the explanation and (c) I am really, really lazy.
