All things considered it wasn't *too* much a spike in difficulty compared to Goetia (which everyone should have defeated already), especially if all KP items have been bought - and really, you need to finish 90 missions to max ascend BB anyway, so you'll be grinding anyway.

And BB is an incredibly good welfare in my eyes, definitely worth shooting for if possible.

There's a fair amount of setups available to defeat Beast III-R/Heaven's Hole (including one that consists only of 1* Servants, and one that consists only of 3* and lower CEs and Servants), but for a large portion of those methods farming enough KP to buy a fitting set of debuffs is required, yeah.
