The Lethal Plague Rogue build focuses on spamming Lethal Strike to deal huge Poison damage with the use of its short cooldown when paired with Mark for Death. This allows your Lethal Strike to have a 1-second cooldown as long as it is hitting marked targets.
Do note that this build is made until Level 22 so you can achieve max Divinity for both classes once you complete all the quests. Any additional points after that level can be slotted into maxing out Mark for Death or more passive modifiers.

Your equipment entirely focuses on stacking Ailment Power to increase the damage of your Plague stacks from Lethal Strike, and Poison Damage paired with Agility to maximize your damage total output. Cooldown Rate is an important affix as well, since this can shorten the 1-second cooldown of Lethal Strike after hitting a marked target.
Make sure to always pick up and equip higher level equipment as you progress so you can benefit from the increased base stats they provide.

We highly recommed equipping Venom Heart as this boosts both your Poison Damage and Ailment Power to match the build. Equipping two Trygon's Tail can be a good replacement weapon for more Poison Damage until you find a better Dagger with the Ailment Power affix attached to it.

Your main skill will be Lethal Strike, which can deal around 2k-4k burst damage on each use when paired with the Mark for Death and Vanish damage buffs. Always initially use Mark for Death on your target so you can make use of the 1 second cooldown of Lethal Strike from the Mark Focus modifier. Additionally, Preparation is for converting your weapon damage into Poison Damage so you can start inflicting Plague stacks for even higher burst damage.
As for your passives, they mostly consist of damage boosts where Toxin Distillation and Dismantling Tactics are the passives that mainly provide higher damage for this build. Critical Hit Chance is also an important damage boost since Lethal Strike can hit multiple times in one use.
| Attribute Prioritization |
|---|
| Agility ▶ Vigor |
We highly recommend focusing on Agility for the majority of your attribute points, as this significantly boosts your Poison Damage and enables equipping of Light and Medium armor. As you progress, always add 1 Vigor for every 2 Agility you invest in to keep a 1:2 ratio between the stats.
The Lethal Plague Rogue build revolves around spamming Lethal Strike to deal huge Poison damage with the help of Mark for Death and Vanish to increase the damage output further. The rotation is as follows:
