Omni Achievement in Vampire Survivors

Refer to Torrona's Box (10G) for actual unlocking that item first. Once you've unlocked it, you need to find it during a run. It adds a little bit of curse but a bunch of buffs as well. The unique thing with Torrona's Box is that it has nine levels instead of eight, and the ninth level (max level) adds a huge amount of extra curse. So, be aware that when you get Torrona's Box to level 9, you're going to need to be quite strong to survive the very buffed enemies you're going to make.
