He produced a pinch of granite dust and powdered diamond, and sprinkled it over Grayth, Maresa, and Ilsevele in turn. Murmuring the words of a potent defensive spell, he armored their flesh against physical blows. Then he cast a spell that provided all of them with the ability to see in the darkness. After that, Grayth blessed each of them with prayers sacred to Lathander, to protect them all against acid in case they encountered the horrible corrosive breath of a green dragon. With their spells in place, the small band advanced to the empty doorway in the stone house adjoining the tower, and one by one slipped inside.
The house itself was large, and likely had been quite comfortable and strong in its day. The wooden flooring was weak and rotten. Grayth, with his human weight and heavy armor, had to move with care, but the elves and the genasi were light enough to stand on it without worry. Large holes gaped in the roof overhead, and moldy heaps of fallen beams and broken shakes lay beneath each collapse. Rotten old chairs still stood around a sturdy table in the center of the first room, in front of an empty stone fireplace. The whole place was somewhat dank and musty.
"There can't be any magic that's too deadly in here," Maresa laughed. "There's a bird's nest in the rafters. Come on, let's see what's in the tower proper."
"Do you still sense the other stone?" Ilsevele asked Araevin.
"Yes," he answered, "but it is so close I cannot tell exactly where it is. All I know for certain is that it is here somewhere."
Araevin and the others followed Maresa through the empty rooms of the old house, looking in on old kitchens and disused bedchambers before they found the doorway leading into the base of the round tower at the house's far end.
Maresa studied it, and started to lean in to look around in the next chamber. A brilliant blue sigil glowed brightly above the doorway, and a sheet of coruscating azure lightning crackled across the doorway. Maresa yelped and hurled herself forward, rolling through the archway as the magical electricity snapped and popped around her. Smoke and sparks showered from the rotten wood of the lintel, and the stink of burning stone filled the air. "Maresa!" Ilsevele cried.
She started forward, but Araevin caught her arm.
"Wait!" he warned. "The sigil is not discharged."
Araevin hurriedly worked a counterspell, striking the glowing blue symbol from its place above the door. The hissing sheet of lightning guttered once and failed, leaving bright spots dancing in their eyes and acrid smoke drifting in the air. The instant the curtain of sparks collapsed, Ilsevele darted into the tower room, an arrow nocked on her bow. Araevin and Grayth started to follow, but a massive iron fist smashed into the doorway in front of them, crushing stone and blocking the way. The hulking arm drew back, replaced by a blank-eyed visage of the same black metal. The thing turned away from them and moved ponderously in pursuit of Maresa and Ilsevele.
"Damnation! That's an iron golem!" Grayth snarled. He glanced at Araevin. "Do you have any spells that can hurt it?"
Araevin quickly reviewed the spells he had stored in his mind, trying to imagine what might damage a hulking automaton of iron.
"Not really," he answered.
"Well, that's unfortunate," said the priest. "Guess I'll have to do it the hard way."
Grayth leaped into the room and aimed a powerful two-handed cut at the towering golem's knee. Holy steel clanged against animated iron with a terrible sound, and sparks flew from Grayth's blade, but all he achieved was a thin crease in the side of the construct's leg. The hulking machine pivoted and smashed its fists down at the Lathanderite, but Grayth backed away across the uneven floor, choosing to avoid the golem's terrible punches rather than try to parry them.
Now we know why the dragons haven't bothered with this place, Araevin thought grimly.
He followed Grayth into the room more carefully. The tower's ground floor was a large, round room with a sagging ceiling twenty feet overhead. The stairs leading to the upper stories were long gone, but rotten posts still stuck out of the sockets in the stone walls, circling the room as they led up. Once the chamber might have been some sort of workroom or laboratory. Old workbenches stood against the walls, and dusty old glassware was being smashed and broken at a furious rate by the attacking golem.
Maresa levitated in the air near the high ceiling, her white hair streaming around her as she hurled magical darts one after the other into the golem, which ignored them.
Ilsevele crouched atop a table, bow in hand. She took careful aim and fired a pair of arrows into the golem's back. One glanced off the thing's thick iron skin, but the other punctured a hole in the creature. The golem boomed and grated, its joints screeching like a rusted gate as it turned to face the latest attack.
"Maresa!" Araevin called. "Forget those spells, they can't hurt the creature."
"What do you want me to do?" the genasi snarled in frustration. "My rapier wouldn't even dent that thing!"
"Distract it from Ilsevele. She has arrows that can pierce it, but we have to keep it away from her."
"Distract it? How?" the genasi muttered, but she moved over to the wall and dislodged a large, loose stone from the wall. She grunted with effort, but managed to maintain her levitation spell and drift back over the iron golem before releasing the heavy stone. "Here, try this, you rust bucket!"
The block dropped ten feet and caught the golem square on the top of its head with a tremendous crash! before tumbling off its shoulder and cracking the flagstone floor. The golem staggered in its tracks, its head marred by a large dent, but the construct simply steadied itself and looked up at the genasi drifting overhead.
Araevin crouched in the doorway, thinking hard. He knew a little about golems. The living statues were common enough as defenses in wizards' towers and magical fortresses. Tower Reilloch possessed a small number of the devices, hidden in various places. Golems were built to be immune to most magic, but some spells could affect them, if in unexpected ways. Magical rust would be the best way to attack a golem of iron, but he had no such spells.
What other elements might serve? he thought furiously. Cold might make it brittle; fire was unlikely to trouble it much. Lightning? A creature made of iron couldn't possibly avoid a lightning bolt…
"Grayth! Back off a bit," he called.
As the cleric backed away, Araevin leveled his lightning wand at the golem and barked out the command word. With a roar like the tearing of an enormous sheet, the brilliant bolt slammed into the golem's chest. Arcs of electricity danced over its body. The golem lurched awkwardly and toppled backward, crushing a rotten old workbench, but it immediately climbed to its feet again.
Grayth chose that moment to dart in at the creature's back, ramming the point of his sword at a joint in the device's armor. The golem whirled on him and knocked the Lathanderite flying with one backhand blow of its mighty fist, but Grayth bounced back to his feet almost instantly. Araevin's protective spell had absorbed most of the blow for him. He started circling in more carefully. Meanwhile, Ilsevele shifted a few feet back, calmly sighted on the same joint that Grayth had pried open, and sent two more arrows deep into the constructs back. Sparks showered in its innards, and the golem stumbled to one knee. Abruptly it belched out a great cloud of horrible green gas, flooding the room with fumes.
Maresa was safe above the cloud, but Ilsevele threw a hand over her face and turned to scramble up the old sockets of the vanished staircase, leaping lightly from post to post as she climbed up and out of the bilious green vapors.
