PoE Ultimatum Mods

List of Ultimatum Modifiers

Let's take a deep dive into the failure rate based on which modifiers are active at the time of failing an encounter. For clarity, failing an encounter is defined as either dying (such that the encounter ends entirely) or running out of the encounter area for too long.

Let's first look at the least dangerous modifiers. Among these, we can see Razor Dance, Razor Dance II, Ruin, Ruin II, Stalking Ruin, Stalking Ruin II, Choking Miasma and Choking Miasma II. This mostly holds true across all area levels, though Raging Dead II makes a showing in the area levels 2 to 72 bracket, and Blistering Cold shows up in the area levels 73 to 77 bracket.

Let's now do the opposite, what are the most dangerous modifiers? Of the more common modifiers, a notable standout is Stormcaller Runes III. These have the ability to overlap and deal extremely high damage when triggered, potentially leading to stuns, which can cause a swift death. The most dangerous modifiers seem to be Limited Flasks (using a flask cancels the effects of all other flasks) and Escalating Damage Taken (particularly if given enough time to reach its maximum effect of 50% increased damage taken). Occasional Impotence appears to be quite dangerous as well; who knew that being unable to deal damage 25% of the time could be a hindrance!
