Change that message so it includes the name of the skill in question. I've heard over time of people making mistakes over this, and since UE is non refundable, I think it's warranted.
I even spent a full 20 points unintentionally in another skill. whoops.
It's why I like the current Echo option. So I can verify which skill / stat I've chosen.
Also, you get a confirmation when you choose Languages:
You have ## UE, how much would you like to spend on (Language)?
(You enter amount)
You want to spend 10.0 UE to gain % of your next level in (Language), correct?
So, something similar like the following could work:
You have ## UE, how much would you like to spend on (skill) [1-20]?
(We don't really need the: You want to spend 5 UE on [skill], correct?) Do we?
If we're not paying attention when we're asked, how much to spend on skill name, then we really do need to bite the bullet. We've had 2 x's to read the correct skill and number.
