Navigate Horologium B1F through B6F, defeat Herald Mastema, and unlock new Main Apps in this Shin Megami Tensei: Strange Journey Redux walkthrough.

Walkthrough
  1. 1
    Horologium B1F: Loop around and take the stairs to B2F.
  2. 2
    Horologium B2F: Take the stairs down to B3F.
  3. 3
    Horologium B3F: Follow the linear path, use the terminal and heal spot, then descend to B4F.
  4. 4
    Horologium B4F: Head east past the D-type locked door. Go through the one-way door north. In the large room with 6 doors, position yourself at the northwest-most door. Wait until the Moon Phase is 7/8 and about to turn Full. Enter the door, then move two tiles west to teleport. If the moon phase is not full, move north one tile, then south one tile until it is full, then go south to teleport.
  5. 5
    In the next area, unlock and go through both east and west doors. Take the west door, then the middle of the three doors. Proceed down the hallway to teleport again.
  6. 6
    Head directly east to find a portal that unlocks a shortcut to this area. You'll find a terminal and Heal Spot. Save and heal, then return west. Collect [Balm of Rising x2], find an elevator, and stairs down.
  7. 7
    Use the elevator to reach 1F. Unlock another shortcut to Horologium's entrance. Return to the elevator and go back down. Save and heal, then descend the stairs to B5F. Recommended armor is the "Life Vest" (Strong vs. Wind, Weak vs. Ice). Prepare demons with buffs/debuffs (Luster Candy, Debilitate) and strong physical or Fire attacks.
  8. 8
    Horologium B5F: Proceed forward to trigger a scene with Mastema, initiating a boss battle.

  • Resists: Gun, Ice, Wind
  • Attacks: Wind, Expel, Almighty, Charm (Great Lament), Instant-kill Expel (Judgement), Wind damage (Untainted Wind), Almighty damage (Mel Faize), and a regular party-wide attack.

Strategy: Use buffs (Luster Candy) and debuffs (Tarunda, Debilitate) up to the +3/-3 sweet spot. Attack with physicals or Fire attacks and Co-Ops. Use Dis-Charm or Salvation to counter early charms from Great Lament. Mastema is considered easier than Law/Neutral path bosses.
