Claude

Has an enchant removal.
Has armor ignoring spells.
Blood Ritual supplies energy to party members running low. As it's an enchantment, it will also improve Alesia's healing with Dwayna's Kiss on those same allies.

Cons

At level 20, he only has 7 skills equipped.
His skill lineup is expensive and slow to cast.
His healing is limited to what little he can steal from a target; some of that being conditional.
Not infused except during the War in Kryta.

Dialogue

Towns and outposts: "I was once a dedicate of Dwayna. Since the Searing, after watching all that I knew and loved perish before my eyes, I have felt the call of Grenth in my soul. What do you think awaits us in the great beyond?"

Droknar's Forge (explorable area): "The Lich was most certainly undead, and yet I don't get the feeling he served Grenth. I guess it doesn't matter now. It is good he has been dealt with."

Shiverpeak Mountains: "Do the Dwarves bury their dead?"; "Funny that we had an alliance with the Dwarves for so long, but I never once saw one in Ascalon City."; "I once knew a ranger who climbed up into these mountains to do his hunting."; "If someone freezes to death, does their flesh still smell bad?"; "Sometimes the steam from my breath makes interesting shapes. That last one looked like a crow."

Kryta: "I've never understood sand."; "It's amazing that Kryta fared so well during the Charr invasion."; "My skin doesn't do very well under this kind of sunlight."; "Not so long ago the Krytans were our enemies. Funny how fire raining from the sky can change all that."; "Somehow, the undead rising from the swamps is not as comforting as I would have hoped."

Maguuma Jungle: "Anyone who can live here can't be all that bad."; "I find the darkness in the depth of the jungle very comforting."; "I like plants as long as they are brown or drink blood."; "I'm not quite sure what to make of the Shining Blade."; "The dry parts of the jungle are my favorite."

Crystal Desert: "Do you think any of these cultures buried their dead? Maybe the bones were buried and the wind uncovered them."; "I could use a nap."; "The bones everywhere really make me feel at home."; "Those sand wurms look particularly nasty."; "Why would anyone come out here to do anything but die?"

"Death has such a lovely smell."

"Take a look around. You will miss this world when you're gone."

"Tell Grenth that Sergio sends his best."

"There are no angels where you are going."

"You will enjoy death. I assure you."

Claude has a battle quote that mentions Sergio, however Firstwatch Sergio has no known ties to Claude.
Claude was named "Valyr Morghulez" during the beta, a reference to the phrase "valar morghulis" from the book series A Song of Ice and Fire.
His skills were updated in the 22nd October 2009 update.
- This added Soul Leech (elite) and Strip Enchantment, and removed Grenth's Balance (elite) from his skills.
Despite primarily using Blood Magic he wields an Accursed Staff, which requires Curses to fully use.
