Within the same month, baby! B)
This might actually be the most efficient level up I've gotten yet... I feel like I've said that a ton, but I legitimately like how much I can keep improving on the grind.
As for what I can say about this level itself... Well, it's the first step on the last half of the challenge, so even if it feels rather simple, it is kind of a big deal. It also is on face value 1/6th of this half, and considering that each quarter is 100.000 EXP, I'm already over 10% of the way through the 3rd quarter of a challenge, so... It feels weird, reassuringly quiet to get a lot of progress in what seems like very little... That is the mark of progress, I'd say :D

Didn't take that long, eh? Less than a month still! :D
For this entry, the most noteworthy thing I can say is that I crossed 700 HUNDRED HOURS in the save file... Definitely spent a good bit of those not grinding and just interruptions XD
Dart still takes damage, and if the information I've gathered is correct, he'll always take damage with the first armor set... We'll see how that information ages, as well as we'll see if I can get another level up this month, which I doubt, but who knows anymore. I've surprised myself more than once in this challenge :v

WITHIN THE SAME MONTH! B)
While this is a pretty awesome, the requirement of 17 thousand EXP for the next level up means that, on an average grinding rhythm, it will take 17 days to get the next level up, meaning that I won't be able to get more than one level up per month. Oh well, it do be like that by nature of leveling up :P
Dart still takes 1 damage from attacks, and I think I will stop bringing this up besides bigger milestone levels, but I feel I should mention it here because I saved BEFORE checking if I stll take 1 damage, and got a small heart attack at the thought that I couldn't decrease Dart's health for a potential continuation of this challenge... But all is good so far, so let's go!
Oh boy the amount of times I accidentally healed while grinding for this level is sincerely silly... TWICE WITH POTIONS.
I do think I'll never stop taking damage in this area, not even from the Berserk Mouse, but I do not want to be caught with my pants down, so I've been maximizing the damage I take in grinds, it only adds between 5 and 10 minutes per 500 EXP, so it's no big deal.
I do think that, even if I didn't maximize the damage I am taking, I will get down to 1 HP long before the challenge ends, but if I keep screwing up like I have so far with the heals, I need to guarantee it harder :v
