tbaMUD Continued development of the CircleMUD core

So far, it seems alright set at 128, I'm just wondering if there's any other implications of doing this that could break things down the road.

You can safely increase it but don't exceed the previously defined constant MAX_STRING_LENGTH.

As for decreasing, you won't "break" anything in so far as crashes, but you may find that you trigger some exceptions and have the MUD shutdown (deliberately through exit()'s) in places where it didn't before, if you decrease it by too much.

However I assume that you intend to increase it to allow for long custom prompts. So yes you can safely do this.
