After looking at the cursed chest video I think that the feature needs something more visual when the cursed chest is opened. I think the light radius or lighting of the dungeon needs to become near pitch black after opening the curse chest so that the player experiences an impending doom. Once the event is over the lighting returns to normalcy. An example of this mechanic is in Act 2 viper temple quest of Diablo 2.
icefall cave lvl 2 is fixed location . got it multiple time when cave was there
I can confirm this, Icefall Caves 2 Cursed Chest always spawns. The dungeon itself has a 50% spawn rate, as it shares the spawn place with Caverns of Frost. It's easy to find as there are 6 possible spawnpoints, and the 3 wrong ones are marked with destroyed catapult icons on the Field of Slaughter. Also 5 spawnpoints are close to the WP. I farmed this chest and my record was 8 waves cleared on normal PTR. Anyone with a better result?
Does anyone know a better Cursed Chest to farm? Halls of Agony Cursed Chest is close to the WP, but the spawnrate is not high enough.
