Completing quests should have a chance for random item drops/loot.
killing mobs should have a chance for random item drops/loot.
You could Implament chain bonuses, so if someone is very active they get rewarded for it.
I was thinking of an item class that would be fun.
Potions of Boon, or something akin.
It would be items that you gain from questiong/leveling/killing.
You could make better ones form quest masters and unique ones from bloodpoints. Even arena ones if you wanted..
They could do things like
(quaff adds negative/bad 50 of a resistance you lose 200 ac and gain 400 damroll for 2 ticks) - Boon of berserking
(quaff adds 2000 hps and 100 ac and maybe even 5 con or something for 2 ticks) - Boon of defense.
Now what would be great about items like these are you can make them stronger or weaker as your hearts desire, make them small ticks so you can't abuse them (can't just quaff a ton and become isnane) because after all, 2 ticks later you're back to normal anyways...
Would help with fighting legendareis, would help with pvp.. leveling, helping new chars level.
Etc.
double exp happens, poop some boons of whatever.
(you could make them all share the same cooldown just like legendary abilites, so after the affect wears it adds another affect that would be 'exaushted after using a boon 100 ticks' and would show in your affects status)
Just a thought!
