Phantom Abyss

NOTE: WITH THE 1.0 UPDATE REPLACING CLASSIC MODE WITH ABYSS MODE, THIS GUIDE IS (probably) OBSOLETE. ASIDE FROM THE FIRST SENTENCE HERE, DON’T BOTHER READING THIS.

This achievement is unlocked by obtaining 5 Relics (don’t know if this includes duplicates) in each of the game’s 4 regions/areas. If you’d prefer to not do 5 complete successful Classic Mode runs for this, the Inferno, the final region of the lot, shows up in temples once you’ve reached the Champion 1 rank. Additionally, if you don’t get 5 Relics from the Ruins or Caverns by the time you reach Champion 1, I would recommend going for them in Classic Mode to avoid having to de-rank yourself (initially and consistently afterwards) to grab them (turns out you cannot de-rank yourself so you kinda have to get the Relics in Classic Mode if you get to Champion 1 too quickly), a strat I also recommend for getting every Relic in these regions due to the multiple Relics you can choose from there.

If there’s anything that you think is worth adding to this somewhat barebones guide, let me know and I’ll consider adding it in.
