We understand that the current drop rate from dungeon may be low since from what you explain, it seems that the main way to obtain relics and glyphs will be introduced in 0.36 and dungeon chests are just secondary way or so (NOT another primary way as mentioned in the patch note)
However what Tacet mentions here is kinda unrelated to the issue above.
The players in the early access notice that from the global chat & this forum, we have some players reporting that they obtain relics from Low level chests (chest Lv. 1-50).
Some of them are not even dungeon chests - but just regular chests.
Your patch notes mention that it should be obtained by completing dungeons.
On the other side there are many players who open a lot of Lv. 100 chests (including Ruby and Diamond) never see any Relics, Glyphs, Crystals drop.
Not a single player who open Lv. 100 chests says that they get a relic, glyph or crystal from them.
Not a single drop from the whole community who open Lv. 100 chests.
That is why we have a strong suspicion that maybe there are some errors in the coding which cause
relics, crystals, glyphs can drop from low level chests but they do not drop from high lvl or Lv. 100 chests.
We really hope that this issue/suspicion can be conveyed the devs and that this issue can be investigated.
Note:
Is it possible that it’s related to this bug? (the introduction of easy lv. dungeons may cause some glitch or shift on the drop percentage or something)
