Eaton

Accurate Provoke (AOE with Soulburn)

Eaton's S1 has a 75% chance of Provoke, which is a pretty good chance of activation. Furthermore, when Soulburned, his S1 targets the entire enemy team, dealing damage (that scales on HP) and potentially Provoking them all. While Eaton's Soulburn is very expensive (20 Souls instead of 10,) AOE Provokes are so powerful that it is often worth the cost.

Self-Care On S3

Eaton's S3 combines a self-cleanse, a self-targeted barrier (that scales on HP), and a self-targeted Immunity buff into the perfect self-help package. The cooldown is a little long (4 turns after Skill Enhancement), but the effects are very powerful, especially if combined with a little cooldown reduction from an ally like Achates or Rima.

Passively Protects Allies

In addition to increasing his maximum HP by 10-20%, Eaton's S2 passive gives him a unique twist on the effect of the Aurius Artifact. He passively takes 30% of the damage taken by a single ally. Not only is this passive the perfect way to foil a team that intends to burn down your Seaside Bellona or Basar before they can act, but because it is a passive, Eaton doesn't even have to move for it to do its job (which is good, since Eaton is very slow).

Light-Elemental

Being Light-elemental helps Eaton both offensively and defensively. Offensively, it means his Provoke never suffers from elemental disadvantage, making it easier to land. Defensively, it means he is a prime target for Dark hero A.I. such as Martial Artist Ken, Specter Tenebria, or Challenger Dominiel, which is good, since it helps him draw their aggro.

Easy to Build

Can you build HP? Can you build more HP? Can you maybe throw in a side of Def and Effectiveness alongside even more HP? Excellent, then you can build Eaton.

Very Slow

Eaton isn't the slowest hero in Epic Seven, but he's pretty damn close. He doesn't really need to move quickly or frequently all the time, since his passive triggers whether he's acting or not. However, a lot of the power of Provoke comes from Provoking a target so they can't use their best moves at the start of a battle (i.e., Provoking an Angelica so she can't set Immunity, or Provoking a Rose so she can't CR push). Eaton will never be able to move quickly enough to use Provoke in this manner, which can be an issue.

No Damage Output

If you look at Eaton's kit, you'll quickly notice he only has one offensive move: his S1. While its damage does scale with his maximum HP, which allows him to hit fairly hard, it's still a fairly vanilla single-target attack. Eaton has to be paired with strong damage-dealers who can handle the offensive side of the battle, because on his own, Eaton's not killing anything.

No Utility Beyond Tanking

Eaton is an extremely one-dimensional hero. He tanks damage for your team, but that's all he can do; he has no helpful buffs or debuffs that can help swing the course of a battle. While he can make a huge difference in a fight by manipulating enemy aggro and absorbing enemy damage, if his allies can't follow up on his endurance, he has no way to help them tip the scales.
