* Mercury versus Malleus. Mercury doesn't know how to make Dungeon Hearts? Why not take on an experienced Keeper who is down to their last dungeon heart, and who has turned their Dungeon into a giant meat grinder designed to wipe out invading armies? Oh, and this is done in the second week or so of Mercury being a Dungeon Keeper.
* Mercury's Azzathra-sponsored duel with the Reaper. Alone, in an arena designed specifically to disadvantage people like her and prevent any clever trick she might pull, against a reputably unstoppable LightningBruiser, with her advantages methodically stripped away from her one-by-one. A "duel" that was, for all intents and purposes, a particularly showy PublicExecution. And yet, despite it all, she starts her tradition of DefeatingTheUndefeatable.
* Mercury versus Zarekos. An ancient vampire ''and'' the sole Keeper of the Avatar Isles, he was an extremely powerful foe. Her solution? Scry-and-die. Teleport behind him mid-battle during the night, catch him, teleport him to the other side of the world where it's the middle of the day (and above the ocean, thus combining two vampiric weaknesses). Sure, [[BackFromTheDead he had contingencies]], but still an amazing victory that turned the tide of the war. The fact that she was dealing with several other threats simultaneously didn't hurt.
* Nero casting the Armageddon spell, thus teleporting all of Ami's minions to his base for a fight to the death? Check. Keepers Arachne and Alphel ''both'' using that opportunity to attack Mercury's base, while only she can defend it? Check. Alphel boosting herself for that fight by possessing a ''legendarily'' gigantic, unstoppable dragon? Check. Alphel making what was already an amazingly unfair fight even worse by the use of a dark god-given anti-magic stare? Check. Ami ''still'' finding a way to win? '''CHECK AND MATE.''' Oh, and her solution also lets her ''replace Queen Beryl'' in Metallia's good books.
* Why hello there, Avatar! Utterly unstoppable, ridiculously powerful champion of the gods? You don't say! Able to shrug off any attack, any spell, any trap Mercury throws at you? My my! A legendary OneManArmy that gives [[EvilOverlord Keepers]] nightmares? Very impressive! But...you've never heard of electromagnets, have you? Mercury ''has''.
* A moment of awesome for the Light happens after the Avatar's defeat when the Avatar sends Ami a horseshoe magnet. Knowing what actually happened in a world of people and gods used to explaining everything by "That's Magic" is a feat in itself.
** Similarly, the Unraveller. "clever application of lightning" indeed.
* The Incarnation of Extinction, a Lesser Aspect of Crowned Death. Totally impervious to all non-spiritual attacks. Beat the snot out of a Horned Reaper. In a position where it could potentially incarnate into the material world, allowing Crowned Death to directly influence it. What does Mercury do? She [[EnergyAbsorption absorbs all of its energy]], dilutes it with Metallia's power, and flushes the magic back into the realm of the dark gods. She didn't just [[DidYouJustPunchOutCthulhu punch out Cthulhu]] here, she '''ATE HIM''' and pooped him out on his master.
* Ami's attempt to dominate one of Crowned Death's undead Dungeon Hearts in its underwater temple results in her being attacked mentally by Crowned Death and paralysed. Enter her sister Tiger, who possesses Ami, uses that link to connect to the Heart, and orders the Heart to flood the underwater temple with chlorine trifluoride. The result: the stone temple catches fire, ''underwater''. The sand of the ocean floor it crashes into catches fire. And the water surrounding the temple ''explodes''. This destroys the temple, obliterates the power source of a set of ancient magical artifacts used by Crowned Death's priests, and kills a ''second'' Incarnation of Extinction.
** During the same chapter, [[DirtyCoward Torian]] actually growing a pair and using his newly-devised Dominate Undead spell to take control of a [[EliteMook death priest]] and using its own rapid-aging spell to disrupt [[GodOfEvil Crowned Death]]'s control over Mercury through his [[AnthropomorphicPersonification incarnation]]. It ultimately fails, but it's a good showing from a character whose biggest contribution until then was kissing up to Ami and accidentally providing her with ideas.
* The evacuation of the Avatar Isles. Multiple Dark Gods join forces to destroy Ami, special corruption is destroying her dungeons, a massive army is closing in on her lands. Not only does she survive, but she uses the Armageddon spell to teleport the invading army into her abandoned base...right before blowing it up with massive amounts of explosives. Bonus points for the later conversation with one of the few survivors, who is recruited by Ami, and who then learns, to her dismay and chagrin, that the destruction of the entire army -- including a revolutionary ghost-covered airship, which this person designed as a special countermeasure to Ami -- was ''incidental''. They didn't drive Ami out, they just got caught up in the side effects of her exit.
* With Mercury getting so many Crowning Moments of Awesome, Mukrezar feels he has to remind the world he's still the most dangerous Keeper around. So, working together with Crowned Death, he gathers an army of all the Dark God's intelligent undead and destroys them them all in a single decapitating strike, crippling Crowned Death's forces to an even greater extent than Mercury had -- and it's implied that he did it to show Mercury up, but ''also'' to get revenge on Crowned Death, and because at least one other Dark God was paying him for it.
