I hear some people are planning a RP event called 'When Hell Freezes over'.
Maybe they could activate some of your rules in that one.

LOL funny!
I know a lot of them wouldnt function well as they were worded, but I didnt spice them up to sound better adapted to 4d. Just kinda showing what worked for them, for example x4 damage here would be pretty insane, so you could do smaller like 25% damage increase etc etc.
I just know how well stuff like this motivates players to either try to kill hard mobs they normally cant, or just grind off some of that xp in turbo mode.
Mayhem on the other mud was fun as hell, there were PKill areas and zones, but this made it all out. It was great on my wizard, if they had quad damage on I had the ability to add runes to my spells which would let me clear hit adjacent rooms, I would just steamplow like 5-6 people at once, life was good.
