RPG 2 – The demons are coming!!!

So... this is more complicated than I thought. Stronghold...
On the other hand, there are no undead creatures around. Hmm... I don't think this is all a trap to eliminate me. I'm not that important a figure. Not yet, anyway. So, there's no particular reason to worry. Then again, who knows... I'll get closer... And the keychain is glowing just in time... Is it predicting an SMS? (:))

- There are a couple of them... (you have a new message)
- It looks like you're late, warrior. The Necromancers have already captured her. We need to rescue the sorceress... In the Cursed Chapel (the elf pointed to one of the buildings, radiating a clear threat and the chill of death), the necromancer Raven is currently performing a ritual, and her (the sorceress's) soul... is enjoying itself somewhere in the sun, completely unaware. You must interrupt the ceremony. Raven is the leader of the Necromancers of Mistrad, and besides, there are many Liches and Undead there, so it won't be easy. But you must somehow interrupt the ceremony! Get to the chapel and see what you can do; I'll be nearby and will help you if needed... Here, take this silver sword... It's a bit heavy, but vampires and other unholy creatures die like flies ;) Keep the amulet around your neck; it will protect you with an Air Shield from arrows.
Good luck, warrior! The elf said no more, gazing thoughtfully as if looking through the chapel...

I take off my cloak, put aside my staff and bow, and my sandals follow... And in a short tunic, I plunge into the sea... the water has given me strength again - I am ready for any twists of fate!

Something soft touches your leg... You instinctively pull away and see, to your surprise, that it's a dolphin inviting you to play in the pink sea before dawn... A school of fish swims by, creating whimsical, colorful patterns in the water...

A few days have passed... At first, I still knew when it was day and when it was night... but soon I found it unnecessary... I no longer cared whether it was day or night.... my "colleagues" were taken away one by one... some never returned... The strong ones remained... They brought in another one... but I don't care about him... he looks weak enough... But he was taken away too... He didn't return... So I sat and waited...

Before you were taken for another walk. A half-goblin, accompanied by two huge Minotaur Guards and a couple of Assassins, took you and one of the Elves and led you to the lizard pasture.
- See that Lizard with the purple crest? That's the pack leader. And the rest... ;) Hehe, his girlfriends. The other male lizards are too jealous, so we separate them to ensure, uh, better results. The female lizards are very loyal to their current partner and are ready to tear apart anyone who approaches him.

You stand in silence for a few minutes, watching the Lizard with the crest and his 5 girlfriends nibbling on mushrooms and some kind of moss in the pasture, about 500 meters away from you.
- Your task is simple... - the unpleasant voice of the dwarf suddenly broke the silence - get a male's tooth.
The Minotaurs roughly pushed you into the enclosure and slammed the gate shut. The pasture was a vast space (about 15 acres) strewn with slippery mushrooms and some kind of moss (although the lizards clearly felt stable on it) and half a dozen natural stone columns. Not far away, six lizards were peacefully grazing... one of them with a bright crest, your target. You are being watched from different sides of the enclosure by almost fifty sharp-eyed assassins with drawn crossbows, so it's better not to do anything stupid and not try to escape... You have a rather dull iron knife at your belt. Nothing else.
The Elf immediately rushed to the nearest column, silently approaching the target. He is now 300 steps away.

Smok, describe your actions and the Elf's actions.
