Reckoning (paladin talent)

Reckoning is a paladin talent in the Protection tree; you will need to spend 25 points in Protection to max it. This talent gives the paladin a chance to gain an additional attack on their next auto-attack, stacking up to 4 times.

Reckoning Bomb
The term Reckoning Bomb refers to an attack that consumes multiple Reckoning "charges" at once, dealing a burst of damage via consecutive attacks. This is done by turning off auto-attack and allowing yourself to be critically hit until multiple stacks are accumulated, then turning it back on to use them all.

Reckoning could originally store an infinite number of charges, which meant Reckoning Bombs had the potential to deal massive amounts of damage. In May 2005, a paladin named Karmerr soloed Lord Kazzak in the Blasted Lands by unleashing a 1,816-charge Reckoning on him, killing him in a matter of seconds.

Shortly after this, Reckoning was hotfixed to store a maximum of only 4 charges.

Trivia

 * Prior to patch 2.3.0, most tankadins would take Reckoning. However, with the addition of a 10% health bonus from Combat Expertise in patch 2.3, many tankadins dropped Reckoning in favor of Combat Expertise.
 * Reckoning appears as an epic Paladin spell in the 2021 Core set for Hearthstone. The artwork depicts the Reckoning Bomb, and its flavor text reads: "He would henceforth be known as "Karmerr, the Doom of Kazzak.""
