Once you hit World Tier III, you can complete the “Eyes of the Enemy” quest, which will reward you with the first Infernal Hordes Compass. You will only have access to the Infernal Hordes if you complete this side quest! It is not a seasonal quest, so make sure to check your priority quests log after entering World Tier III!
After completing the quest, use the Compass and complete your first Infernal Horde. However, you will quickly realize that you might not have any other Compass, as they do not always drop during Infernal Hordes.
The following Endgame activities have a chance to reward you with one or more Infernal Compasses:
- Helltide Chests
- Nightmare Dungeons
- Completing Infernal Hordes
- Crafting at the Occultist with Sigil Powder and Forgotten Souls
However, as some players have already pointed out, the fastest way to earn Infernal Compasses may simply be to grind Helltides:
It is also good to know that in World Tier III, you will only have access to Tier 1 Compasses. Tier 2 and higher will drop in World Tier IV. Additionally, you can also upgrade your Compass to higher tiers by using Abyssal Scrolls.
You can find Abyssal Scrolls in the following ways:
- From Infernal Hordes Chests
- By Salvaging Infernal Compasses
Lastly, if you want to focus on farming Infernal Compasses, here are some tips for you:
- Grind endgame activities that have a chance to drop additional compasses
- Use your Abyssal Scroll to upgrade to higher tiers. It is not worth upgrading Tier 1 to Tier 2 with the Scrolls, so keep them higher, more challenging compass tiers
- Higher tier compasses have more chance to give you an Abyssal Scroll upon salvaging.
