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.
both Warlic gets several in a row at the end of Nythera's betrayal quest chain. Nythera, having managed to steal Warlic's power, and kill him, tries to fight the elemental avatars. She loses, and is forced to admit that she is flawed, and resurects Warlic. Warlic, once resurrected, forgives her, and then reveals that his death and everything that followed was part ofhis plan to make her realise this without a full scale battle that would destroy reality. And then he protects her from the elemental avatars, and forces them to retreat.
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...
And if you fight alone you're up against a titanic firey dragonic monster, which has up until now been an invincible juggernaut. You can still win singlehandedly, without too much difficulty. Not to mention the guitar riff the whole thing is set to...
In the Earth Orb saga, you must fight the Guardian Dragon, on foot. You win.
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.
Sepulchre afterwards. His response to being betrayed is to pull the blade out of his chest and proceed to fight against Drakath unrelentingly. The wound doesen't even slow him down. And when you ally with him against Drakath it turns out his attacks were powerful enough to do reasonable damage, even on foot.
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.
The following quest is a Titan battle against the same enemy, only this time it's winnable. What makes this different from other titan battles though is that you get to team up with Sepulchure.
The battle against the Super Mega Ultra Darkness Dracolich. It easily dwarfs you even with your dragon in grown form, and you still win. The combination Pre-Asskicking One-Liner and Prophecy Twist also helps.
