FF1 monster collection?

[BG-57]

The monsters are roughly ordered in the places you first encounter them.

Gray Ooze: Marsh Cave

Ocre Jelly: Terra Cavern (rare encounter)

Basilisk: area around Citadel of Trials

Tyrannosaur: area around Lufenia (rare encounter)

Iron Golem: Temple of Chaos B4F (Tiamat II's floor, rare encounter)

The Iron Golem was the hardest enemy to find by far (even more so than the Warmech!). It doesn't help that they are in the second to last floor of the Temple of Chaos when your party is low on spells and healing supplies.

I used this trick when wandering that floor: If I encountered Areos, I killed all but one, had one guy make my party invisible with the white robe and the other three would use healing helmets and the healing staff to heal my party for free. After usually four or five rounds my party would be back to max HP at no MP or item cost.
