General Homunculi Changes

Homunculus can now critically hit
Greatly reduce the RNG variation with an auto-reroll system on level up: for each stat that got no gains at all (+0), the game will automatically re-roll the odds to see if you can get a +1 to the stat. While it's possible that you still get a +0 in the end, at least you get a 2nd chance. Note that the reroll does not permit you to get a +2 or a +3 in a stat. This happens automatically whenever you level up. You will see the notification of the system kicking in within your chatbox.
All Homunculus have their level up stat adjusted. In general, all homunculi is getting a stat buff in EVERY category. You will see the standard deviation to have greatly narrowed (aka: less likely to be screwed by RNG), while retaining the potential high ceiling in almost all cases.
