Sir Lynna is an extremely rare elite which is one of three located in the Fractured Peaks in Diablo 4. Watch the Sir Lynna video in fullscreen over at YouTube (select 1080HD from the gear icon).
Each zone has at least three extremely rare elites, so the same goes for Hawezar, Scosglen, Kehjistan, and Dry Steppes. These Extremely Rare Elites are targets for the Trophy Hunter achievement — which rewards Player Titles: Merciless, and Pursuer.
Sir Lynna, in particular, might be of interest to Necromancers because he drops a rare-quality one-hand weapon named Darkblade.
There is a wanted poster at the bottom of the stairs of the Kyovashad Inn that says:
SIR LYNNA: Once a promising and devout member of the Knights Penitent, the heretic Sir Lynna has renounced the Light and now lives in darkness. The faithful should avoid Kylsik Plateau, where she has been seen most recently.
The Darkblade has some interesting stats for Necromancers who pursue a Shadow Summoning build that relies on Decompose and Blight skills. Among the stats in the Darkblade you can find 2.0%+ Shadow Damage; 2.5% Damage to Enemies affected by Shadow Damage Over Time (I think I fixed the spelling in the screenshot). Lucky Hit: Up to a 1.4% Chance to Execute Injured Non-Elites.
You can bring the Darkblade to the Occultist in Kyovashad to add a Codex of Power or an Aspect (a more powerful version of the Codex of Power). In my case, I applied one available to me during the Server Slam. But you might find something better with unrestricted access to all Codex of Power and Aspects found through your Level 1-100 journey in Sanctuary.
My Legs slot had a rare-quality item which added +1 to Bone Prison. Though, my Skill Tree had no Bone Prison, that leg stat unlocked Bone Prison for free, so I didn’t have to waste a Skill point to unlock Bone Prison. The Rimescar Cavern dungeon in Fractured Peaks has an interesting Codex of Power reward for Necromancers which rewards Aspect of Plunging Darkness.
Aspect of Plunging Darkness: Bone Prison spawns a pool of Blight that deals 50% bonus damage over 6 seconds.
Adding the Aspect of Plunging Darkness (Codex of Power) only cost me Veiled Crystals x 6 and 9,726 gold at the Occultist; and this action converted the rare-quality Darkblade into a Legendary Item named Flammard of Plunging Darkness with the exact same stats at the Darkblade, but adding the Imprinted Aspect of Plunging Darkness’s power.
This Darkblade improved my gameplay experience during the Server Slam after the hotfix that made Skeletons last longer. But the skeletons were still dying. I was able to handle rare elites better with Bone Prison and the shadow damage increase from Dark Blade.
In the video below, I engaged combat with another Extremely Rare Elite — named “Wrathful” Osgar Reede, listed in the Trophy Hunter achievement. This one however was 15 Levels above my Level 20 Necromancer. The Server Slam level cap was 20. Impossible to kill this dude solo right? Well, almost impossible. My skeletons were dying as soon as his AOE spontaneously flared in three directions every few seconds. So I had to rely on long range Blight and Decompose. Decrepify slowed him long enough for me to summon 3 new skeletons after casting an enhanced Blood Mist. Only problem I had is that Bone Prison can be destroyed (which is a shame). But for the small bits of time Bone Prison was up, I could see some generous damage dealt to Wrathful Osgar Reede. You can watch the video in fullscreen here. Killed him in 6:44 minutes. Hopefully, Blizzard figures out a sweet spot for Skeleton survivability versus bosses when the game launches, because the Server Slam version died too fast for my liking rendering my Necromancer to run like a sissy, and cast Blight and Decompose on the go.
