I have had this idea in mind for a while and I have finally decided to post it on the forums. The new expansion is coming soon and I am sure it will be nice for people to have some Lvl 30 epics which is all well and good... but Turbine may add this to the back burner as their final quest pack if it ever comes to it. One legendary quest.
What would make a quest legendary?
This quest will not be Elite. It will be marked legendary with its own custom entry window with warnings.
This quest is supposed to be endgame that is only playable once per life of you fail the quest. If you beat the qiest you can run it again a different way to see what else you might see. If your group gets wiped.... gotta TR or ER to try again.
Story: From what I currently understand there are 16 Gods of Eberron. This quest will involve all 16 of them and your reward will come from one of the 16 Gods depending on how you play out the quest. The key to this working is content that is not static and varying enemies popping up throughout the quest to fight you. Might be nice to debut some dragonbourne if you follow the track of the Church that hates them.
Anyways moving on from that tangent, this quest should bring forth all the enemies or allies associated with the Gods. This means you can betray all of the friends you have made on your Journey or do the quest in favor of them. Betraying the silver flame would be interesting of their God was doing something it shouldn't. I know people love their pots.
Now this is where it winds up becoming interesting. This quest will be a raid that requires at least one person, of every class with each using a different epic destiny. Throughout the quest, whichever track you take, their will be an array of situations where you have Str Checks, Int checks, Dex Checks, Con Checks, Wis Checks, Cha Checks, Skill Checks, and Wilderness, Religious, and Arcane Lore Checks. Bard will have to serenade people to get passed them, Fighters will have to intimidate guards, Barbarians will have to solo a giant in order to keep the party from fighting an overwhelming ambush in an arena, stuff like that. Or you can fight them, and have the optionals change, like alerring the God of your violence, etc.
Make every party member do their part to complete the quest, explain where the Warforged Souls go. Etc.
Add magic free zones, penalties for religious toons in certain sections of the quest. Have moments where globe of invulnerabolty will be useful to protect the party from poison gas filling a locked death room. Every possible idea can fit in this quest.
Although its a rudimentary post, i want your feedback and ideas that you would want in a legendary quest.
The reward would be one item from the God Chest of Privacy of said Diety you saved or destroyed. And there should also be a special bonus for this quest as well. Completing it with a flawless, ingenious debilitation bonus, persistence bonus should do more than just give XP, like God Weapons, A Teleporter, Something Random and Cool. +10 tome of mastery or something. Post your ideas guys.
