Have forgotten your pants.
Pants are a mortal invention! They do not belong on the legs of a being such as yourself.
Charge up the passageway with your fellow demons, letting out horrifying screams and spitting webs at any dwarf we see, then killing them.
Focus our fury on the dwarves furthest from the spire. Our brothers and sisters can handle the ones closer to the spire.
With your arachnid strength, you scale the inside of the spire, and your legion follows suit. Through a small hole, a creature with pink flesh and voluminous amounts of brown hair sticks its head out. You are the first and last thing it sees.
The weakened section crumbles as you throw your bulk against it, sending the creature down to the depths where it is swiftly shredded into a viscous red mist by the numberless armies beneath you. The stone above you is much more artificial in construction, consisting of stairs carved into the very spire itself. While the divine nature of the metal embedded within has prevented your kind from ever harming it, the dwarves have done your work for you. Now, there is no stopping your wrath.
You reach the top of the spire, and it is here that it opens into an artificial, subterranean structure. The walls and floor have countless scenes of mortal trifles scratched into them; that these pitiful things should choose to deface the very land they live on with petty depictions of their existence is revolting. There are more of them here, and they drop the curved implements in their hands, letting loose piercing screams and turning to flee.
Their strength is not enough to harm you; you are twice their size, and in these low stone tunnels you must nearly crawl to get through. You beat them out of the way as you advance, leaving your brothers to descend upon them.
Ahead, a door closes off the end of the tunnel. Four more of these small creatures, clad in the same gleaming metal as your hide is made from, wielding hammer and shield, enter through the stone construction, which is quickly slammed shut behind them. They yell out, and advance, shields raised in preparation for battle.
The rest of your kind are still scaling the spire. You must become the tip of the spear, forming a wound for them to salt.
You...
