Buff and Debuff

'Damn, I've lucked out!' Fein jumped and raised his fist in the sky with excitement.

Both of the abilities he got could help him and they directly had increased his combat power!

[Rudimentary Field (Active)- It could slow down the enemies within thirty meters of the user by two hundred percent.]

'Rudimentary Field, an active debuff skill that would slow down the enemy within his thirty meters, could help him restrain speed-type enemies such as Fey. And the faster the enemy, the stronger the effect of the debuff! What's the concept of two hundred percent? That's literally more than double. He could also use it for escape, as a slow enemy would have a hard time catching him!
