"Nerf an instance"

[Joubarbe]

Hi,

I'd like to know if there's an easy way to adapt an instance (Molten Core) at level 80. I could, of course, EventAI and change stats of all mobs, but maybe there's an aura that lower the level of players who are entering the instance. Or another way/spell/magic action to make players compatible with the instance.

Thanks !

EDIT : I'm using Trinity.
EDIT2 : Sorry for the prefix, it seems I can't edit the title. (Opera)

Adapt it to level 80?
Giving the players a debuff that decreases their stats by some % ?

Yes, that's what I'd like to do
