E1M5: Optifort Prime (HYMN)

E1M5: Optifort Prime is the fifth map of HYMN. It was designed by Michael Kargas (Optimus) and uses the music track "Mist," composed for Heretic by Kevin Schilder.

Essentials
Take the Ethereal Crossbow behind you if you need it then go forward to a hallway with four doors. Open the south-east door to enter a room with various items, including a Dragon Claw and a Bag of Holding behind the barrels, then kill the waiting gargoyles before pressing the switch in the south-east corner three times to lower a pedestal holding the blue key. Take the key then go back to the starting point and open the east or west doors to confront some golems, then open the door in the north wall between a pair of blue gizmos to find a switch that will open the nearby bars. Go outside to deal with some waiting disciples of D'Sparil, then go to the graveyard on the east side of the fort to find a trench which is guarded by nitrogolem ghosts, sabreclaws, undead warriors and one or more ophidians. Drop into the trench and go down to the bottom of the steps (an iron lich will be waiting on thou art a smite-meister skill level or higher), then bump into the large water pillar here to lower it and reveal the green key.

Head round to the west side of the fort, where some metal bars have lowered and released a maulotaur, then climb up to the top level of the wooden structure here to find a Hellstaff before running into the maulotaur's cage to find the yellow key. Climb out of the cage and head south into a small maze, which you should follow to the center to find a Silver Shield, a Bag of Holding and a Chaos Device; taking the yellow key lowered some bars here, allowing you to head through an open gate and follow a narrow ledge to the blue exit teleporter.

Secrets

Go to the Torch and open the black wall on the right-hand (west) side to find a secret passage leading to two Crystal Vials, a Quartz Flask, Gauntlets of the Necromancer, four Wand Crystals, a Silver Shield, and as you go back, a Quiver of Ethereal Arrows. (sector 22)
 * 2) Head south in the starting room and take the door to the west that leads to a hall with gargoyles. Head south to the wall to open several alcoves. Enter the one second from the left side and press the switch to open the wall in the south-east corner. In this maze-like area, you can find three Wand Crystals, two Claw Orbs, two Quartz Flasks, a Mystic Urn, three Crystal Vials and an Enchanted Shield. (sector 89)
