I have always wondered why no game has thought about this.
A scroll that a player can buy, or it could be a drop or a quest reward - that would allow a player to be a powerful world boss.
When the player would use the scroll there would be a server wide announcement as to what zone the player had spawned in (not allowed in cities) (players would have to find the world boss).
The player would have some cool boss abilities and mechanics, or he could use the abilities he already knows and everything about him is just a much more powerful version.
It would take a lot of players to kill him.
Players would get an item, marks of ascension, and some other random goodies.
I think it would be fun, I think Ascension needs World Bosses to help build community and I think it would add another cool feature to an already cool private server.
Scroll cool down (before any other player could spawn as a World Boss would be 4 hours.)
Thoughts?
