Check the mysterious structure

You avoid several patrols, moving carefully through the shadows, but two goblin scouts spot you near the entrance and draw their rusty, worn swords.

Damn! With an invisibility spell, you can avoid this combat! But it's too late!
They try to hit you with uncoordinated strikes. Their lack of strength is obvious; you sidestep the first attack, parry the second, and the swords of the poor goblins break. With your sharp steel sword, you cut them down before they can even react properly. They scream and fall to the ground covered in blood.

The corridor opens into a vast chamber with torches, and there glows a mountain of gold, jewels, and... A big red dragon egg that looks like a majestic jewel.

The ruby scales pulse with inner fire; it's beautiful

But the gold isn’t just loot. Something is moving and looks at you, it's a small grey goblin armed with a magic sword covered by shadows and a chain. He's nude and his voice resonates inside your mind. "I'm the treasure goblin, and you will be my anal whore... relax and spread wide little girl."

Little girl? This goblin is sick and can't even manage to recognize a human male!
Disgusted and angry, you prepare your sword.

You can fight him, but the scout's screams have already alerted the entire camp. You’ll have to end this quickly, or you’ll be overwhelmed.

You can attempt a feint, grab the egg, and make your escape. It’s risky, he may strike at you as you pass with an opportunity attack, but if you trust your speed, you might get out before it’s too late.

What do you do?
