Now, if you intend to farm Hell Countess for Diablo 2 runes over a longer period of time, most likely in search of a few Pul – Ist runes or several, it becomes more important to consider run speed and build selections.
Because of her native teleportation abilities and her ability to cast teleports quickly, the Sorceress is automatically the best class for running The Countess. Because only a small amount of damage is required to kill her players1, travel speed becomes the most important consideration. As a result, 200fcr is ideal for countess runs, but 105fcr is also very effective. Since she is immune to fire and cold, lightning attacks are particularly effective against her, and both Lightning and Nova sorceresses are likely to be the best choices for running her in the game. hybrid sorceresses, on the other hand, are perfectly acceptable. Last but not least, even fire Sorceresses and fire/cold hybrids can outrun her in a reasonable amount of time. If the mercenary kills her minions (which are not fire immune) and clears the way for the mercenary to kill the countess (which is particularly effective if you use static field), the path to the countess is cleared.
Having said that, if one possesses the Engima runeword, other classes can perform exceptionally well in The Countess’s company. There is no competition if a Sorceress is present, as she will be significantly more swift. However, if Engima is available, she can be run by almost any class in a short amount of time. The Barbarian, in particular, is lightning-fast, his fcr frames matching those of the sorceress, and the Necromancer and Paladin are equally adept at getting the job done quickly. The majority of common builds for each class are effective as long as the only source of damage is not cold-based, and preferably not fire-based (though this can also be effective as described previously).
The Map and the Runtime
If you’ve gotten your Countess running build up and running with reasonably decent gear, and you intend to put in a significant amount of runs (for example, farming several Ists for a 6ist (D2 ladder weapons), then attempting to find a decent map will pay off in the long run. Countess running builds up and running with reasonably decent gear Rerolling maps until the tower is reasonably close to the Black Marsh waypoint, and then checking to see if the path down to the countess has numerous long paths between levels, are the steps I take to get there.
It is possible to find short paths on every level, but it is extremely difficult to locate a map that looks like this. So, if the paths have a reasonable average length, I would run 20 or so runs to determine what the average runtime is like. According to my personal experience with a 200fcr lightning Sorceress, it doesn’t take much effort to find a map where you can complete runs in approximately 35 seconds without stopping. As a result, this is what I recommend as a goal. Runs under 30 seconds are very possible, but they frequently necessitate the use of a map that takes a long time to roll.
Chances of getting a rune drop in Hell
For the Countess in Hell difficulty, I manually calculated the correct rune drop chances and presented them in this thread. Due to the interaction between her item tc and rune tc (as described in the linked post), this is a fairly complex calculation, and the most commonly used drop calculators are significantly off by a significant margin. Also included in this guide will be a set of tables containing the results.
