Thank you all for the feedback. First of all, this is mainly Cahit' project. I just gave him my thoughts and suggestions in the early stage.
I have to agree though with Ironsuomi about the title rewards, this is not a thing we should add in Emps-World. It's just straight up messy.
About the location of the Doomsayer, we've considered other places but we've mainly chosen to place it near the Grand Exchange because doomsayers want to be heared, and to be heared they'll have to be in crowded areas.
The other quests currently active at the GE are temporarily ones, and thus will be removed soon. Also, when the quest is completed, the doomsayer should be placed to another location, waiting for another dangerous threat. Making the GE quest free again.
I also put some thought into the Demon Defender. It should be a non-tradable item with a requirement for wielding it should be a combined level of 170, in both the Attack and Strenght skill. This is an average of 85, equal to all demon weapons, and it should be dropped in two or three parts, obtainable from different demon bosses/monsters. To combine the parts you will have to have finishes this quest. Which should be easy considering the requirements of the quest should be the same as for wielding the defender, but obtaining the parts will be alot harder.
