v1.0.1:
Major:
New Dead Rail Event – Visit the Imps at their home, and finally get a H-Scene for them. Players that have cleared Dead Rail may need to use the ‘Replay’ function.
Added a ‘secret’ epilogue scene after beating the main story, beating Pyraxis in the simulation, then going to sleep (People were a little sad that Pyraxis didn’t seem to get a resolution, so here we go!)
Minor:
New Cheat: ‘One Punch Man’ – defeat all enemies in one hit!
Mosquito Girl’s First Encounter: Her HP and ATK now scales from 50-60, and 6-8 depending on the day you encounter her. (This was done to help prevent an auto-loss if encountering her on Day 2/3)
Added some extra dialogue to the first bed talk. (I was just experimenting with what deeper dialogue options might look like for fun and decided to slip it in.)
Fixed Daily Mag not fully increasing with Wit, and nerfed the Mag Gain by 50%. (Now 100 Wits = +50% Daily Mag. This should balance out the Esper tree being 50% more expensive than the others.)
Kitsune Support: Now actually works (sorry) – implemented a scaling cap equal to 12 + Monster Rep
Small Mortivira nerf: All sources of damage in this fight deal 1 less damage. Black Candle no longer deals extra damage in phase 2. (Mortivira ended up being the hardest battle and a little RNG dependent, because not only did you have to deal with strong minions, but her spells were just as scary as any of the other superbosses. Hopefully this adjustment will give players more breathing room)
Misc:
Fixed some scenes not resetting Protagonist or Tatsumaki’s lust
Fixed Explosive Vial A causing Poison and Bleed to proc twice
Fixed ‘Discern’ not working in the Azazel fight, causing her clones to pop instantly
Fixed individual doppelganger scenes requiring x2 potions
Fixed Cauldron 3’s Tooltip from +1 Wits to +2 Wits.
Fixed Acid Flask A and B not granting an additional Flask.
Fixed HP Regen from Cauldron7a not getting subtracted when selling. In fact, it was actually getting added again when selling!
Fixed a crash when looking at Data Khaos’ second tip.
Many many Typo fixes
