Open the Dread Lich’s Boss Upgrades tab
Open Boss Upgrades while playing the Dread Lich. The official Malignus press kit shows Deep Reservoir, Necrotic Aura, and Phylactery in the Lich’s upgrade tree. Find those entries in your build and read their descriptions before spending points.
Start with the defensive role you want
Necrotic Aura is the clearest starting point if you want to build your defense around the Lich and its skeletons. The press kit describes the Lich raising the aura while skeletons fight adventurers inside the circle. Plan a defensive spot where the Lich and its skeletons can fight together and where intruders are likely to pass.
Compare the other upgrades in your version
Deep Reservoir and Phylactery are named options in the documented tree. Check what each does in the build you are playing and how it fits your setup. If your goal is the aura defense, decide whether another upgrade addresses a problem you are seeing before diverting points. The press-kit description names the options without establishing costs or a purchase order.
