This list does not include MI’s or epics.
Mythical Black Scourge - Used to have good stats. Got hit with a double nerf in terms of stats and the damage scaling of non-mastery pets. Will be better in 1.2.1.6 thanks to occultist getting chaos RR, but Salazar’s blade is still just better. I personally like the approach of leaning into the unique aspects of items when rebalancing them. In this case it would be the pets given by the item.
Mythical Spark of Ultos - Can you even call this a pet item? Zero bonuses to any relevant skills. Frees up a ring slot if you don’t want to run 2 Glyphs of Kelphat’Zoth i guess.
Gate to Many Worlds - Offhand is a tightly contested slot and this one simply doesn’t offer enough. Needs something really crazy if you want to enable arcanist as a pet class. Cool concept though.
Mythical Blood Orb of Ch’thon - Used to be a way to get ele to chaos conversion before fiendgaze tome changes. Currently the only way to get 100% acid to vit conversion, but there aren’t good enough use cases for this. Maybe increase the health loss and buff the stats to lean into this unique mechanic more. Still one of the cooler items conceptually.
Mythical Crown of the Winter King - Something something FoA… Cold pets are a bit of a meme currently. Hybrid builds just aren’t a thing sadly.
Mythical Bane of the Winter King - Has partial conversion which can only be completed by Crown of the Winter King. But wait, the crown gives full conversion so the sword isn’t even needed. Has tons of flat damage, but again, cold pets are underwhelming and two-handers are hard to justify for pets.
Mythical Guardian of Death’s Gates - (This is mostly for death knight) Playing a single RR mastery for a vit build is painful. As much as I want to make a viable skeleton death knight, ritualist always ends up being better in almost every way possible. I don’t know if soldier skills have the capability to add anything interesting for pets aside from juicing up Field command.
Mythical Witching Hour - Suffers most from being a two-hander. No fiendgaze tome, which is a huge dps loss for chaos builds. Almost requires you to use 2 voidwhisper bands to maximize phys to chaos conversion uptime, but you will probably use them regardless. Also, maybe the proc should be changed back to a button press, since it is such a massive part of the item and the uptime is only 50%. You sometimes end up having the proc on cooldown when you need it the most.
Mythical Plaguebearer of Dreeg - Can achieve 100% vit to acid conversion with ghol’s mark. But then you need to enable dual-wielding to get 100% phys to acid. Gets indirectly nerfed in 1.2.1.6 with the addition of acid RR to necro. I think the pet bonuses could be redesigned to enable acid skeletons.
Claw of Hagaraz - Good stats, but thats it. Ends up being an item you use when there is nothing better. The call of the grave mod doesn’t even work on pets, maybe it should be changed to duration or flat cdr (same thing for Guardian of Death’s gates).
