The Thexian Dragoons have sent me into The Deep Forge to see if the mysterious bronze idols are cold to the touch. These bronze idols are like 2" tall. They are VERY hard to see.
Touch 8 idols and kill a hammer
A small bronze idol, 27, -6, 5 , near the entry, down ramp to the left.
A regular bronze idol, 129, 0, -73 , in the main room at the far NW corner near lava flow.
A heavy bronze idol, 110, 1, 9 , in the forge room on a table
A tiny bronze idol, 14, 0, -51 in the main room on center platform left and across from Cruhm the Overseer.
A bulky bronze idol, -129, 0, -41 , in the main room at the far SE corner near lava flow.
A glowing bronze idol, -13, 0, -250 , to the right of Firelord Kaern in the corner.
A dull bronze idol, -105, 0, 21 , on the library floor up against a wall, to the left of a desk.
A shiny bronze idol, -20, -11, -157 , in the boss room, inside the lava pit in front of Firelord Kaern. You may swim down into the lava to pick it up (after drowning the magmaborns), or you may kill the Firelord, lower the lava again, and then pick it up. If you choose to swim, the lava deals very little damage.
