With Group scaling getting buffs last night, here's the best Bountiful Delves to complete solo on Tier 8 for today.
Everything About Delves Guide Delve Rewards Guide
These rankings are for fun, and to give a general idea of how difficult each day's Bountiful Delves are on Tier 8 — Tier 8 because it's the highest reward right now. This is a general ranking and will take into account the Delve and Storyline that are active from a solo DPS PoV. Different classes and gear will cause your experience to vary, but should give a general idea of how difficult the Bountiful Delves are.
Since you only have a limited number of Restored Coffer Key anyways, if you skip a really tough delve, you can always use it on a different delve on a different day.
These rankings are for SOLO players, and now that group Delves are harder, I imagine a lot of people are trying to do these solo now.
Not much has actually changed for SOLO delves since yesterday:
These changes slightly offset each other as the spell damage is a nice change to make things easier, but you have to contend (read: skip) a new miniboss which could spawn on top of an objective.
The Spiral Weave today is the same one from 2 days ago, and is straightforward delve with small groups of mobs at a time. The casters mobs with a «bolt» deal less damage and you really only need to contend with where the lieutenant is.
Otherwise, there is no typical boss in this Delve and the final encounter is 4 waves of mobs with the final one being a creature with about a third of the health of a typical Delve boss. Make sure you have cooldowns for it to beat it's AoE damage cast and this should be an easy clear today.
