If you ever decide to come back to this again and update it with more quests... I might have a suggestion for a return to the Hall of Banterous Bosses.
Do you possibly have a working link for this? This link doesn't lead me to anywhere
I have no idea what happened there or why the link broke for no reason, but it's fixed.

So, You forgot to mention a couple of things in the questguide. (The Trollnium spear, The Time Travel quest, both of which I found by pure luck, and Felix Falora) and one move in particular is pretty broken. But it was an even better game than when it first came out, and the addition of those last superbosses was a definite must. If you ever do update this again, I suggest an edit to the quest guide.
The Trollnium mines really isn't a quest, it's just a dungeon. The Time Travel quest was intentionally left out for the sake of keeping it hidden.
