Site Review

Dungeons: DoTs are only effective in dungeons for newer players or in the Hall of Water stages. However, newer players will opt for Baretta over Thrain due to his superior leader skill and better attack bar manipulation in the skill, Turbulence. In the Hall of Water, single-target DoTs like Orochi’s or HP-scaling damage works far better, making him pretty obsolete there too. For newer players with limited resources, you shouldn’t even think of building a Thrain or use him just for dungeons.

Raids: While his 3rd Skill’s increasing damage over time does sound appealing in raids, especially since all the attacks will go on a single-target, the lack of debuffs makes him a poor choice here. Neither DoTs nor stuns work here, and his 1st skill is useless here.

ToA: Thrain’s pretty much a one-trick-pony, but damn does he do a good job here. A double DoT team with both Baretta and Thrain is sufficient in doing damage for the entirety of ToAH. Thrain does a better job than Baretta in DoTs due to the lower cooldown on his 2nd, and his 3rd Skill has a 100% chance of stunning the enemy when DoTs are active. Even when built on HP, he does a good amount of damage against any ToAH stage boss. He is a complete upgrade to his already decent Water brother Hemos, and will be one of the best CC monsters you can get for your ToAH team.

PvP: You can build Thrain as a damage nuker build for funsies here to see some fun numbers on his 3rd Skill. However, he is in all accounts pretty useless in PvP. DoTs aren’t that great here due to the prevalence of cleansers and immunity buffers, and the randomness of his 3rd Skill makes it unreliable to be used effectively. To top everything off, he has very poor base defense, and in fact one of the lowest in the game (gotta make up for that surprisingly good base HP and Attack right?).

How to Counter

You’ll never see a Thrain in a PvP defense, but just in case, immunity monsters will counter anything Thrain does. For newer players, Veromos will work just fine against him. You shouldn’t worry about him that much, just focus on the other damage threats on the enemy’s defense instead.

Other advice:

  • Make sure Thrain goes after (aka slower) than your Baretta. This is to make sure that his 3rd Skill can help stun the enemies when necessary
  • Just get as much HP as you can on him, there’s absolutely no need to have attack on him for ToAH
  • You only need 45% accuracy in total for ToAH, so it’s pretty easy to get it from substats

Editor’s Note

Thrain is one of the best monsters you can get for a manual ToAH team early on. His DoTs and reliable stuns makes him fulfill two roles: A DoT machine and crowd controller. While it’ll take some time to get him (since he isn’t farmable), he is definitely a monster worthy of being built. However, players that already can clear ToAH will have zero need to use him anywhere in the game.

Amazing DoTs monster in ToA. However, if you can already clear ToAH without him, there’s no need to use him at all.

Comments Rating 5.63/10 (3 reviews)


– AoE DoTs with low cooldown and 100% activation rate
– 3rd Skill is a reliable stun with good damage
– Great base HP and attack


– Abysmal speed
– Low base defense
– 3rd Skill is completely random, making it hard to use if you’re unlucky
