Rise of Legends: Valley of the Mad, Temple Sands

Choose three of your best developed heroes. Giacomo has gone mad because of the poisonous gasses here, you have to keep him safe while he wanders around and freaks out.

It's quite simple, just follow the inventor and take out everything that threatens him.

It's time to take care of the genie that tricked you in the very beginning of the Alin campaign. Pursue him through the whole map and fight off everything that he sends at you. There are glass cages around here with units trapped inside them, take time to free them for free reinforcements and for a bonus quest.

At the end, genie will summon two Glass Golems. You'll have to destroy them before you kill him. Concentrate your legion's fire on them, and eventually take out the genie himself.
