When assigning stats, the text boxes only let you type in numbers. This is good, but they will happily accept decimal points, which seems unintended.

If you attempt to copypaste a number into the text boxes, it strips out everything non-numeric. Decimal points are still permitted, but more exploitably, you can paste negative numbers. If you paste in multiple negative signs, it strips out all but the first. The negative number will be accepted, allowing negative ability scores, which naturally wreaks havoc on the combat system. This also awards you stats points–adding -4 to your Agility gives you 4 stat points to work with. If you copypaste in a number like -1000000000000000000000000000000, the game starts displaying numbers in scientific notation (“You have 1.0E+30 unspent stat points!”), which is probably because it’s storing the stats as floating point numbers instead of integers.

I know it’s storing them as floating point numbers because I did this: Imgur: The magic of the Internet

This was done by adding a very very large negative number to a stat, increasing the rest of them by 10,000 or so, and then re-adding the original very very large number without the negative sign. Floating point numbers don’t work when you add numbers of very different magnitudes, so the game didn’t adjust my unspent stat points correctly when I was increasing things to over 9000. Then I just reset my stats at the University of the Arcane and distributed my entirely-too-many points normally.

You can also add numbers so large that floating points just give you “-INF”, “INF”, or “NaN”, which also break things.

TL;DR: Don’t let me use decimal points or negative numbers during stat allocation, and store the stats as integers instead of floating points.
