I have spent about 15 hours total in Torghast thus far, and I can’t quite tell if I’m having fun. Which probably means I’m not.
The design of this endgame activity is weird, which may be a result of Blizzard’s whiplash direction. It was originally very challenging for a solo player, then it was made to be harder presumably to not surprise players at reaching an unkillable (to them) final boss, and then made much easier across the board. Which is fine, because this is the primary source of Soul Ash, which is necessary to craft Legendary armor this expansion. And everyone is absolutely expected to have one. The recently-released Twisting Corridors with its cosmetic rewards is a better place for challenge.
But even that aside, it doesn’t feel great. Each run takes me 40-60 minutes and it is a commitment. If you don’t kill the last boss, you get nothing. If your gameplay gets interrupted by something, you get nothing. If you die too many times to random things even before the last boss, you get nothing. So, given the risk, you are highly incentivized to kill every mob pack and scour every crevice for Anima Cells to gain more power. If you skip things on the early floors to try and finish more quickly, but end up not having enough juice to kill the boss, well, you get nothing.
Oh, and don’t forget that the elites and bosses all get a rapidly-stacking 10% damage buff every dozen seconds or so. Berserk timers would have been one thing, but really? Why is that necessary at all?
When you first unlock Torghast, you just have access to Layer 1. Beating a Layer gives you Soul Ash and unlocks the next Layer. Each Layer gives you a decreasing amount of Soul Ash – it goes 120, 100, 85, 70, 60, and so on. The good news is that Layers stay unlocked, so that next week you can instantly go to Layer 5, beat it, and gain all the Soul Ash from that and the lower Layers automatically (435 total in this case). Plus, by virtue of having beaten Layer 5, you can do Layer 6 next week. Or this week, if you want to put in another hour or so for 50 Soul Ash.
The bad news is that unlocking 5-6 Layers right away on a toon is exhausting and will burn you out quickly. All of your alts start at Layer 1 just like your main, and Legendaries are gated behind Torghast, so it is not as though you can readily ignore it, even if you only PvP. You could “take it easy” and only run one Layer at a time, but that’s going to delay your Legendary by weeks.
Finally, the Anima Powers you have available are really hit or miss. There are sometimes fun combos to unlock, like when my Guardian Druid got to auto-cast Roots on enemies that stuck me when Barkskin is up, and when Roots breaks it deals 4000 damage to nearby enemies. Oh, and Barkskin was all but permanent with duration boosts. That combo let me charge into multiple mob packs, do a few Swipes, and then the Roots breaking for 6+ mobs simultaneously dealt 24k damage to everything.
When you roll in with an Affliction Warlock though, you get runs where your Seed of Corruption gets buffed five times. Which is fine for trash, but doesn’t do anything for the boss.
Torghast is probably one of the most interesting design decisions Blizzard has implemented since Scenarios. Reminds me of Dungeon Runs in Hearthstone. But is it fun? Eh, it can be. Sometimes. It’s also exhausting, kinda formulaic, and also required. If Blizzard leaned more into the overpowered abilities angle, or if each floor guardian gave a little Soul Ash, then I could see it being better.
