It doesn't work so. Imagine yourself dropped somewhere in the middle of nowhere, without any idea of what is your mission. What will you do? You will search for water, roof and food. Imagine, that you don't need water, roof and food. What will you do? You will sit down and think. That's it. Same goes for a new player.
What.
Is that what you do in all your games? You sit there and wait for a flashing quest marker to tell you what to do?
Replace the wand with some gem, that can be inserted in your wand and make it more powerful? Use turtleshell to improve your shield, or a part of the shell as a shield. Doesn't this sound better? A beast can have a ring in his stomac, for sure, but not wands, swords, shields etc.
That huge turtle is more than big enough to have swallowed a wand. And crafting isn't in the game in full yet, and it doesn't include Diablo/Divinity 1/2 gem socketing.
Also, you're complaining below about not knowing about the existence of a lockpicking party member, and you expect a new player to understand about crafting a wand with a gem found inside a turtle?
You don't get the idea. I am a new player. I don't know that I can find a thief somewhere far away from here and I don't want to break my weapons while trying to open the chest. All I feel is dissapointment that the chest can't be open. But if I open it right now and hear something like "uhh that was hard. I am not sure if I can manage some more of these without learning thievery" from my main charecter, I know, that in future I may need a thief or points in thievery. The game should be newb-friendly.
The game is lets you pick the prison cell doors with 0 Thievery in case you get a character stuck in there.
Treasure chests are optional. You can come back for the chest later and even mark it on your map. Just because you see something doesn't mean you need instant gratification. Before you reach the turtle beach you can see a treasure chest at the end of a rainbow. You can't get it then, you need to come back later. Same idea.
There's also a buried treasure chest nearby the turtles which isn't locked.
