you forgot:
-no casting
-no autoattacking
-no wanding
-no instant spells
-no abilities

i mean thats abit harsh. basicly what i denied was "spending gold" to get your toon items.
i went hard after any goldspending because i didnt want this event to be
"who can spend the most mats and gold to craft the best toon in 24h" but you are free to make an event like that

And 10min cds ok thats something. (Lay on hands, prep, cold snap, speed summon, etc) just felt like way to strong cds for a fight like this.
