Before Entering the Mycofields

The Mycofields is an anteverse zone accessed from the containment lift area in Cascade Labs. The environment applies two distinct damage types that must be addressed separately: extreme heat and spore infection. Entering without protection for both will result in rapid health loss.

Required Protection

The Fire Proximity Suit is the primary heat counter. Head protection that blocks spore infection is a separate requirement — heat protection alone does not prevent spore damage, and spore protection alone does not reduce heat damage.

Route Planning for First Entry

Step 1: Verify Loadout Before Portal Entry

Check that both heat protection and spore protection are equipped before stepping through the portal. Once inside, returning to craft missing gear requires a portal trip that may already be complicated by active damage.

Step 2: Establish a Safe Retreat Path

Upon entering, identify the nearest cover or route back to the portal. The Mycofields contains flowing lava and open areas where heat damage is constant. A clear retreat path prevents situations where damage forces a panic exit through unfamiliar terrain.

Step 3: Confirm Protection Effectiveness

Move a short distance from the portal and observe health status. If heat damage ticks through the Fire Proximity Suit, or if spore infection symptoms appear despite head protection, leave immediately. These failures indicate missing or insufficient protection layers.

Recovery Advice

If protection fails during the first entry:

  • Return to Cascade Labs
  • Check that the Fire Proximity Suit is equipped in the chest slot
  • Verify head armor provides spore protection (not all headgear does)
  • Repair any damaged equipment before re-entering

Do not attempt to push deeper while taking preventable damage. The portal world does not become safer with distance.

Boss Encounter: Armored Exor (Tarasque)

The Armored Exor, sometimes referred to as the Tarasque, is a creature found in the Hydroplant area of the Mycofields. It is the second evolved variant of the Exor, with 650 head health and 600 torso health. Its attacks include melee damage (50 sharp), ranged projectiles (25 sharp), and acid grenades (30 acid).

Preparation Checklist

  • Weapon: Bring acid or electrical damage sources to exploit weaknesses
  • Healing: Carry enough supplies to recover from multiple hits
  • Armor: Repair all pieces before the fight; damaged armor reduces survivability
  • Inventory: Store rare materials before engaging — dying with valuable loot creates a difficult recovery

Fight Approach

The Armored Exor is aggressive and uses ranged tracking projectiles. Maintain distance when possible and use cover to avoid acid grenades. The creature's bullet resistance means firearms are less effective than melee or elemental weapons.

If the fight goes poorly, retreat toward the portal. The creature does not follow across zone boundaries, allowing a safe reset.

Farming Routes and Material Collection

After establishing safe passage, the Mycofields becomes a renewable material source. Plan each trip around a single objective to reduce risk.

First Farming Trip

  • Objective: Collect visible materials near the portal
  • Duration: Short, with retreat at first sign of trouble
  • Goal: Confirm material locations and safe paths

Second Farming Trip

  • Objective: Extended collection run
  • Preparation: Full inventory space, repaired gear, clear return route
  • Goal: Gather fungi-related materials without engaging the Armored Exor

Boss Attempt Trip

  • Objective: Defeat the Armored Exor
  • Preparation: Best weapon, full healing, empty inventory for drops
  • Note: Extract any rare materials found during the fight before engaging

Common Mistakes and How to Avoid Them

Mistake 1: Entering with Only a Hazmat Suit

The Hazmat Suit provides radiation protection but no heat resistance. The Fire Proximity Suit is required for the Mycofields heat environment.

Mistake 2: Forgetting Head Protection

Spore infection is a separate damage vector from heat. Head armor that blocks spores is mandatory even when the Fire Proximity Suit is equipped.

Mistake 3: Combining Objectives on First Visit

Attempting to learn the map, farm materials, and fight the boss in one trip increases the chance of losing progress. Separate these goals across multiple visits.

Mistake 4: Fighting the Boss with Valuable Loot

Carrying rare materials into the Armored Exor fight risks losing them on death. Store valuable items before engaging.

Mistake 5: Staying After Protection Failure

If heat or spore damage becomes active despite equipped protection, leave immediately. Pushing deeper while taking preventable damage wastes healing and complicates recovery.
