Hataan

Hit Chance Debuff (Especially Soulburned)

Debuffing enemy Hit chance may not seem that impressive early on in Epic Seven, but it can save your team from a lot of damage if luck is with you. Hataan's S1 has a particularly good Hit chance debuff, as the skill can be Soulburned to ignore Effect Resistance, making it that much more likely to hit.

Clearing Potential

Hataan isn't the best at clearing small mob targets, but his S2 triggers a second time if the first use kills an enemy. Since his S2 is single-target, it lacks the big wave-clearing potential of farmers like Vildred or Lena, but it can still help accelerate a farming run or put in some extra damage on a boss that summons adds (i.e., Azimanak).

AOE Attack Buff Uptime

Having an AOE Attack buff is pretty crucial for clearing higher-end content. Hataan is a fast unit, his S3 has a 3-turn cooldown when Skill Enhanced, and his Atk buff lasts for 2 turns. That much buff uptime makes him a pretty decent choice for the role.

Easily Outclassed

Hataan's weaknesses stem from one simple fact: there are many other units who can do his jobs better. If you need damage mitigation, most Knights or Soul Weavers are better than Hataan's S1. If you need a farmer, you want one of the many farming units who has AOE, all of which will outperform Hataan. And if you need an AOE Atk buff, there are a lot of other heroes -- Fire-element and not -- who can provide that, usually with a host of other utility you could benefit from in the bargain.

If you pull Hataan early in your Epic Seven career, he can fill a useful utility role in your team. However, most players will likely pull stronger, more focused heroes that can bring more to the table in the longterm.
