Saving Throws: Constitution, Intelligence
Skills: Choose two from Arcana, History, In­vestigation, Medicine, Nature, Perception, Sleight of Hand

This is clearly RAW, but admittedly this class is not in the Players' Handbook (PHB), so let me bring up information from the PHB. There is a paragraph called "Customizing a background" on p125, which states that player groups are free to create any Background they want, giving their custom Background a total of two tool proficiencies or languages. But that sounds like it may be considered homebrew territory for some purists. The following is not.

So, according to the rules, being good (in particular, proficient) at picking locks and disarming traps is not exclusive the the Rogues class.

I appreciate your input. Isn't the Artificer a different type of rogue, like a subclass? I know in DnD they have them separate but in fantasy settings, I've usually see them as a subclass of Rogue. To me personally, I wouldn't want other classes to do what a Rogue is mostly known for because then it defeats the purpose of having a rogue in your group if everyone can do everything. It's the same for any class. I would like each class to remain unique. This would go back to the whole spell scroll situation. It should remain with only spell casters.
