Paladin Leeroy

Paladin Leeroy is a character in Dark Souls.

Location
Near the end of the Catacombs as a White Phantom.

Later near the end of the Tomb of the Giants as an Invader.

Plot
Paladin Leeroy first appears as a summonable for the Pinwheel boss fight in The Catacombs. His summon sign appears on a ledge that the player has to jump down from the sarcophagus area.

Leeroy later invades the player near the waterfall in the Tomb of the Giants if the player is not Hollowed.

Should the player defeat his phantom, they will find Leeroy's armor in Gravelord Nito's chamber.

Lore
Paladin Leeroy is mentioned in item descriptions to be the first Undead hailing from the Way of White. Wielding the treasures Grant and Sanctus, he ventured into Lordran on an unspecified mission: perhaps to obtain the Rite of Kindling, or to vanquish Nito. As Grant and Sanctus are both mentioned to have been granted to Leeroy long ago, and that Leeroy is named as the first undead from the Way of White, it can be inferred that he is from a distant era that is able to interact with Lordran's present time thanks to Lordran's disrupted time flow. Leeroy is assumed to have met his fate at the hands of Nito, as a corpse with his armor is found there. Little else is known about him, as he has no dialogue whatsoever.

Strategy
Leeroy's weapon, the Grant Great Hammer, deals Strike and Magic damage and can hit overhead, so dodging rather than blocking is advised. That said, he spawns on a very narrow ledge, so it may be challenging to not fall off (or have him fall off). It's useful to lure him back to a less limiting battlefield, and finish him off there.

Leeroy can heal with his Talisman, if given enough space. He may have enough poise and defense to resist merely attacking him at this point, so be ready to backstab him if he tries this.

Leeroy employs Wrath of the Gods, an AoE spell that deals high damage and inflicts high knockback, particularly dangerous since he spawns next to a cliff. Rolling while he casts it will negate its effects.

Trivia

 * Leeroy's name may be a reference to Leeroy Jenkins, a now-famous World of Warcraft player for his antics. Similarly to Paladin Leeroy, Leeroy Jenkins was a paladin class, further reinforcing the reference.
 * Leeroy (at least in his White Phantom form) does not have the required Strength to swing Grant one-handed.
