Ash finally gets to be awesome at the end of ArchKnight. It was worth the trouble.
It's also possible to get one yourself through a massive bug currently present towards the end of one quest chain which causes the boss to have the same HP and damage as the ensuing Titan Dragon fight. Several classes can actually kill it, most notably the Doomknight class, whose Carve (HP steal) skill drains about 15% of the target's HP per swing and can regenerate completely from up to one hit per turn.
This troper once hit 128... on a weapon that tops out at 40 damage (it was a crit on an element that tore that enemy to shreds, but still).
Ever got a 130+ damage hit on a weapon with 23-27 damage? Granted, this troper was using the Power Attack skill which boosts damage by 75%, and it was a critical hit... but still awesome nonetheless.
On May 18th 2011, DragonFable players were killing waves so fast THEY BROKE THE COUNTER.
Grams taking down Sepulchure's castle with Bugs.
Our character beat Death. Twice.
The entire rematch fight against Akriloth. I mean, come on. You can't say it's not awesome when it's one of the few bosses that let you invite OTHER PLAYERS to fight against a gigantic dragon. Not to mention you have a badass new sword for the occasion...
In the Earth Orb saga, you must fight the Guardian Dragon, on foot. You win.
The Fire Orb saga. ALL OF IT.
Drakath impaling Sepulchre with his own Blade of Doom. He then tops himself by using the Ultimate Orb to fuse with Fluffy to become the dragon seen in other Artix games.
The fight against Dragon Drakath. Even though it's a Hopeless Boss Fight the work that went into the cutscenes is palpable. The music that went with it doesn't hurt either.
