What are Resource Draining Effects in Diablo 4?

Diablo 4 is a game of numbers, even if you turn them off in the settings. It all comes down to resource management, damage per second, and armor ratings. Once you cut away all the pretty graphics and flashy sounds, you’re just playing a big calculator, really. This being said, the game really is a marvel of modern gaming. One of the latest number games Blizzard has added to the game with the launch of Season 1 is the resource-draining effects in Diablo 4, but what is it, and how will it affect your precious numbers?

What are Resource Draining Effects in Diablo 4?

There are a million almost unexplained mechanics in Diablo 4. So, you would be forgiven for having to research a few of them. The latest; the resource-draining effects, have only just come into play and are giving a few players some grief.

The first thing you need to know about this new mechanic is that it is only active inside nightmare dungeons. Entering a dungeon with a resource-draining effect in Diablo 4 will have your primary resource constantly trickle away unless you have a way to keep it topped up.

Most builds rely heavily on their primary resource, be it Fury for the Barbarian, Mana for the Sourcerer, or Essence for the Necromancer. Having your powers taken away like this can result in some pretty tricky play. You need to keep an eye out for this new effect in Diablo 4 and plan accordingly.

How to check for the effect

The best way to check for resource-draining effects is by looking at the nightmare sigil you use before you activate the dungeon. If you hover over your chosen nightmare sigil in Diablo 4, you can check the effects. Anything with a resource drain affix will result in your primary resource constantly draining unless fed.
