At most his regen would be 31...and even then that makes no sense, as the Magic level set from last chapter said it gave him 14 health regen...when magic items give, at most, like 4 health regen. Like sure it's a set effect, but it was from what, 4 pieces? And it also gave him more stats than his first of its kind rare level necklace? Even if the set only gave health regen as the entire bonus, it giving 14 health regen would be pushing the logic, and yet it gave an assload of stats too. The sword wasn't mentioned as crafted from the drops either, and all that dropped in terms of swords was a normal steel longsword, so that'd also have no extra impact.
And of course, one attack took him to under 20% HP, so did at least 240 damage. Then the enemy leveled up, and hit him twice in sequence. Like huh? He's dead. Like I get that these types of manga (manhwa here?) tend to have a fair bit of inconsistency, but this is just absolute nonsense. It's not like it would've been difficult just to actually track the numbers properly, especially given that the game so far plays in small numbers, and have him have a total of 100 HP with the equips + damage mitigation from the defense, so the boss is hitting him for 26 damage per hit, which the necklace would heal in 3 seconds after the double hit and 2 after the first hit.
