For as long as I can remember, I’ve been doing delves on Tuesday, and at the very minimum, I can make it to level 80, sometimes being just shy (hundreds or even just tens of points) of the Stage 8 rewards.
But last week and this week (and possibly the week before last week, but I don’t remember), something has changed: I can’t get past level 60, because when I reach level 70, I have no more sigils left, as no raven has spawned in any of the rooms on level 60.
Again, I’ve been doing delves every tuesday for as long as they’ve been around, and this is the first time (well, second now) that I’ve been unable to reach level 80 without purchasing any Tiers from shop.
So now players need to spend 30 gems in order to get at least 1 sigil (to do level 70, and I assume a valraven will drop there) and collect Stage 7 and Stage 8 rewards. 30 gems will get you 50 chaos shards, 10k gold, 2 mythic ingots, and a chaos orb from the stage rewards. That used to be free, almost every time (occasionally if you did the room multiplier order wrong, you couldn’t collect enough points to finish stage 8).
