Great chapter good to have a new one after so long, missed this.
some stuff skipped will use spoiler tags just in case
Karen's backstory:
Been doing this for 3 months, joined because inspired by Bacon-sama, only able to handle monsters on floor 1-2, join team to get stronger faster, her goal to be able to handle monsters on floor 3 by herself.
Why the team abandoned her, yes they are jerks and used her as bait but
the monsters were coming in both directions, because MC's weak presence they didn't know he was taking out those monsters as such he heard them, but yeah they thought they would be swarmed from both sides.
still evil but u can see why they did it.
I don't know why this stuff is skipped but explanation of how skill points are gained and which 3 he allocated before jumping in to save her
1 in strength 1 in dexterity and another in quickness, also the mask kinda sticks to his face when he puts it on
1 skill point gained every floor u advance total, so furthest overall, highest reached 50 in this central dungeon = 50 stat points, if he went to his own dungeon would have to go to floor 51 before he got a stat point.
