Part 31

In the first room, use minions to open stone coffins. The top-right coffin contains a key. Return minions to the main entrance room.

Head down the left path. Avoid watchful elves. Open stone coffins around the giant pillar when elves are not present. The key is on the side opposite the entrance, on the left when facing the elves.

Continue to the next room. Open stone coffins on either side of the entrance; they do not contain keys but will trigger an attack from a guy in black. In the back of the room, alcoves contain chests. The key is guarded by watchful elves on the right. Lure elves away with your Overlord, then have minions open the stone coffins. This yields the last key and opens the Inner Sanctum. Return to the main room and proceed through the previously blocked door.

After a scene, head up the stairs to grab a minion spell and the last root node. Trolls will appear when you try to break the node; kill them first, then break the node.

Head through the opening to the right of the broken root node, returning to the bridge. Follow the path to Oberon. Send minions to attack him. After a scene, kill the enemies that appear before continuing to attack Oberon. Dodge incoming roots.

After each wave of enemies, send minions to damage Oberon. When he says, "Finish this," attack him with your Overlord. Grab the shield spell and replenish minions. Head through the path behind Oberon to the Dwarven Lands.

In the Golden Hills, head up the path to a new waypoint gate. Kill sheep to the left. Continue towards the dwarven village, kill dwarves, and pillage. Use minions to plug up dwarf houses.

At the back of the village, behind barrels, find a tower object for mana. Continue through the village to an area with slugs. Push a cart over the slug hole. To the right, free and then kill trapped elves. Kill dwarves and plug their houses.

Return to the cart over the slug hole, head up the hill to a dwarf party area. Kill all dwarves, loot the area, and get a minion spell upstairs.

Head back to the cart over the slug hole and break the barrier next to it. Kill slugs and dwarves, then continue to another barrier.

Break this barrier and kill the surrounding dwarves. At the end, a scene reveals elves trapped by slugs in the mine. You must fight a rock giant. Turn the wheel to bridge the gap, leading back to the waypoint gate. Break the barrier to fight the rock giant.

To defeat the rock giant: Set a guard marker by the barrier, break it, lure the rock giant back slightly, and have your green minions jump on its back while you assist with your Overlord.

Enter the mine by breaking the barrier. Elves will run by. Break barrels. Follow the path to a scene with a giant slug eating gold. Break the barrier. Head left to fight the giant slug. After defeating it, collect the gold. Elves will mention more trunks deeper in.

From the slug room, head right. Take a right path for loot, then continue to a room with barriers. Before breaking them, take a path leading to dwarves and another trunk.
