After the ultimatum of Path of Exile, despite its launch and streamer priority drama, this Val-themed expansion has proven to be a good addition to the game due to its quasi-gambling mechanism for looting. Another aspect of the ultimatum is that Trialmaster will spawn many monsters in each wave, many of which end up as rare enemies with stronger affixes, which makes them stronger and harder to kill than ordinary enemies or magical enemies. However, there is a way to use it for Path of Exile players and the followers they summon.
Breath-stealers can use minion construction in Path of Exile to be very powerful, especially for wizard summoners, such as necromancers. Considering that the modifiers of the killed rare monsters are all transferred to the withered spores, it can get the affixes such as "other allies can not die" halo; effectively preventing the player and their minions from being killed for the duration of the withered spores Die, or unless it is killed. Necromancers also have their own affinity with the aura, this version takes advantage of this, and provides many superimposed buffs for any followers.
The main minion used for this build actually depends on the player's preferences, because the build is very versatile in terms of equipment and working methods, so it can be used for summoning skeletons or resurrecting zombies. Auxiliary gems are also interchangeable, except for POE Currency, they are likely to be the most suitable for Path of Exile, creep damage, and every creep skill in the elemental army. The former is a general-purpose damage multiplier, but the latter is more interesting because it makes the minions more tanked due to elemental resistance bonuses, while also increasing their elemental damage and applying exposure on hit
Given the versatility of the design provided by Path of Exile and the number of modifiers, the main recommendation is to let the magic game "trigger slot spells when using skills" so that it can be used for weapons. Another useful application is "Restore x% of life when you block", which is especially useful for necromancers who donate bones, use Lumis blends, and get some block nodes from the passive tree.
This will keep the Necromancer always safe, thanks to all the lives restored through Buy POE Currency and other useful buffs, which may include basalt bursting to reduce physical damage. The Ultimatum introduces Lifetap Support for Path of Exile, which can also be used to allow the ghost to cast utility buffs more frequently.
