Some consider Oni as the best KR hero. At level 10, he has 650 HP, medium armor, and 25% chance of instant-kill with the Death Strike.
Pretty impressive stat.
But I was somewhat disappointed by his actual performance; wasn't durable enough and lacked consistency.
Once I've seen him kill 3 forest trolls in a row in less than a minute. It's great. However, that's a rare event.
Actually, the chance of survival in 1 on 1 with big enemies like Dark Slayer and Yeti was like a coin toss. You never know the result.
When Death Strike doesn't bring them to death in 3 or 4 tries, he kneels before them.
I still consider him as one of better heroes though. Just not up to my expectation.
Maybe because I'm not a fan of any chance-based skill.
