The Aspects considered high-tier are extremely powerful, but have limitations compared to the Meta weapons. Their peak power levels are similar, but they possess less build flexibility.
Moros
The main combo for using
Aspect of Moros is to activate an Omega Special, then spam Attacks to trigger explosions. The Blasts are powerful and pair well with any of the percentage-based Boons.
Throw a
Clean Coil Hammer upgrade on and you are for an ez dub. The only thing limiting Moros is the high Magick requirement, and the time it takes to be constantly channeling.
Anubis
The best hidden Aspect in Hades II, the Staff's
Aspect of Anubis alternate moveset is completely busted with the right build. As long as you start with
Heaven Strike or
Flame Strike, you can't really go wrong from there.
Melinoë can place down the Attack's damaging field, then use Special to pull enemies into it. This combo works with both standard and Omega Moves. Once the enemies are inside the damaging field, you can focus on movement and dodging until you need to repeat the process.
The low-maintenance playstyle makes this one of the easier Aspects to achieve a victory once you get the hang of its unique mechanics.
Charon
Aspect of Charon is the best Omega Cast Weapon out of all the Aspects. For the price of one Omega Special, you also get an Omega Cast with increased AoE.
The most common strategy is to build around
Apollo as your primary God.
Lucid Gain is essentially infinite Magick with because
Aspect of Charon you are instantly exploding your Cast. You will want an Epic or Pom the
Lucid Gain a few times if you have any hammers or secondary Boons that increase your Magick cost.
Single target damage is huge, the AoE is massive, and other than channeling time, Charon is one of the safer Aspects to use.
Morrigan
Aspect of the Morrigan has a few really strong builds. The multi-hit Attack can be paired with an on-hit Boon like
Flame Strike, or utilize the increased AoE of
Nova Strike
Regardless of the specific build,
Aspect of the Morrigan has access to Blood Triad, so you always have the capability to deal high burst damage.
Against most standard enemies, spamming Attacks with a few Specials thrown in will be more than sufficient. When facing Guardians, however, you'll need to learn how to optimize Blood Triad combos.
Nergal
Honestly at Rank I, the
Aspect of Nergal will feel very underwhelming. The horrendously slow attack speed makes it take forever land 21 Strikes and become Berserk.
Once you've rank it up a few levels, the healing during Berserk makes
Aspect of Nergal a very forgiving Weapon. Focus on using the Omega Attack to rack up strikes, and you will quickly understand why this Hidden Aspect ranks so high.
Nyx
The Black Coat's
Aspect of Nyx produces a Nightspawn that splits your Attacks and Specials in two. Based on this mechanic,
Wave Strike and
Flame Strike are the go to choices when wearing Nyx's Coat.
For room clear speed, no one really does it better than
Aspect of Nyx with
Shimmering Rockets. The Nightspawn split rockets combined with the bouncing Special rockets make every standard encounter feel like a free pass.
With a bit of extra damage from the Omega Boost plus the splitting Nightspawn for easy room clearing, Nyx is a great Weapon. The Nightspawn mechanic does feel a bit limited during Guardian encounters, since it doesn't help as much in 1v1 scenarios.
Thanatos
There are two main problems with the
Aspect of Thanatos. First off, you really really want
Psychic Whirlwind, or at least
Furious Whirlwind to improve your Omega Attacks. Secondly, the Aspect is only going to work well for you if you are really good at not taking damage.
Mortality and its crit damage chance resets every time you get hit with even the tiniest amount of damage.
If you played early access, try out Than axe again because it has been heavily buffed!
