A couple years back, I played a lot of D&D with some of my friends I met back in high school. One of the GMs I played with ran the longest campaign I have yet played in, and after the first character I created became something of a nuisance because the GM in question likes to give player characters abnormally large opportunities to gain power (Ex. Not fudging on a drop table when a series of critical successes resulted in a level 4 encounter dropping a Tome of +5 Dexterity), I sent him off to become an NPC and forged a new one.
The character I settled on is still my favorite D&D archetype. A stout Fighter/Dwarven Defender by the name of Hirograr Toren the Third.
Maxed out as a combat meat-shield with high STR and CON, Hirograr had many escalating crowning moments of awesome throughout his adventuring career. His favored weapon was the now locally famous "Dwarven Key", an enchanted Adamantine Warhammer, he wore magic Adamantine Full Plate, and bore an Mithril Large Shield of Arrow Catching. This ensemble, tied with his feat specialization in Sundering made him very, very nasty when paired with ANYONE who wanted or needed their equipment to remain in one piece.
The peak of these was an incident aboard a ship the party had chartered travel on to reach a tournament being held on another continent, where a key character was supposedly going to appear whom we needed to make contact with.
Inevitably, as the cliche is always played out, they were ambushed by pirates. As the pirate ship drew nearer to overrunning our vessel, our party readied for boarding action.
The GM had other plans, as his intent was for the pirate vessel cliche to be subverted by a surprise attack by a Kraken, who, after proving a threat by sinking said pirate vessel, would come after us...
... What the GM didn't count on was my Hirograr launching a pre-emptive strike against the pirate ship by launching himself at the oncoming pirates using the ship's one functioning ballista, manned by the Elf Arcane Archer who had read the +5 Dex book, and supported by the party Bard with a ridiculous Cha score.
The result was a dwarf plowing into the center-mass of the pirate vessel like a cannonball, the Adamantine armor functioning as a weapon caused the dwarvish projectile to ignore the hardness of the ship, and simultaneously reducing the falling damage incurred being fired like a weapon into a solid object to very little, by compare.
This left Hirograr to solo most of the pirate crew AND deal a significant amount of damage to the kraken in the confusion, and escaped by targeted by a Fly spell, delivered by said Arcane Archer's weasel familiar, lofted onto the enemy pirate ship using a magic hand cantrip.
We beat the kraken afterward, with far less difficulty than the GM intended (We were below the effective encounter level by 2 at the time), and he had to give us bonus EXP for the impromptu assault on the pirate ship which was supposed to go down in the D&D equivalent of a cutscene.
And after a letter home to the dwarven capital city, the Dwarven Navy in that campaign setting now has a secret attack.
It was the best session, ever.
