  • Mage hand is the kind of spell that is incredibly useful and dynamic in actual ttrpgs, and incredibly difficult to design around in a video game.

    A GM is going to consider the distance and weight limits of the spell, and determine of it makes sense of not. If you stole The One Ring from Frodo, for example, the GM can pivot and make the world react to that.

    The video game has to program all possible uses of the spell while also trying to keep a prewritten story on track. If you steal The One Ring from frodo, the game would have to reinvent the plot dynamically, which isn’t really possible. The end result is that they have to severely limit the uses of Mage Hand.

    Because Mage Hand is so potentially chaotic, it can’t be as useful as it would seem. The same would go for the spells Fly and Invisibility. Imagine the Black Gate of Mordor. If there was a level 6 wizard, they could use fly + invisibility to get everyone safely over the wall. Now, sure, it would take a while waiting for spell slots, but this is supposed to be the most fortified pass in the entire world. Even GMs have problems with this. Suddenly every remotely secure area needs a mage on staff detecting intruders, or permanent enchantments. At that point, Fly might as well not exist.

    Edit: I forgot that fly and invisibility both require concentration. Oops. Still, now you only need a level 6 mage and a level 4 mage, which is still pretty easy to pull off.


  • TLDR: number of possible passwords is x^y where x is the size of your alphabet and y is the password length. Increasing y is better than increasing x.

    It’s not immediately obvious, but it is pretty straightforward math. It has to do with password length vs alphabet size.

    Let’s look at an 8 letter lowercase only password. Each time you increase the minimum length, you increase the maximum number of passwords by 26 (the number of letters in the alphabet). So it would be 26x26x26x26x26x26x26x26 or 26^8 which is 208,827,064,576. This is a lot of passwords, but pretty easy for a computer to brute force.

    Let’s add the ! symbol. This means there are 27 options or 27^8. The total number of passwords is now 282,429,536,481. A bigger number, but not by much.

    If we only have lowercase letters but increase it to 9 letters long, then it increases to 26^9 which equals 5,429,503,678,976. We’ve jumped from millions of passwords to billions with passwords only 1 character more.

    If you allow all symbols and numbers, but also increase minimum length, you get the best of both without creating difficult to remember passwords.

    This of course ignores the primary way people get past passwords: by asking the user for their password. It also ignores that an intruder is going to check the most common passwords and not just try them all. Adding numbers and symbols doesn’t really change the most common passwords though, since dragon just turns into Dragon1!
