I'm not sure if I should call this a game-bug or an art-bug really but one of the interesting things I've noticed is that when using Bloodied Block against hard to block spells and attacks such as electricity, the negative penalty applies first, and then the increase happens. However, if the negative penalty would take the result below one, it obviously can't because there is no die image for less than one. The funny part though, is that when the increase happens, you'll occasionally see the die image actually read '5' or rather the required number to complete the block, yet the block will still fail.
Nice find I've always thought it could be so. Turns out it has been all the time But what's the bug? Want to see die results of below 1?
No, I'd say the bug is showing the die actually reaching the required number value, as in it will actually show the number five, and then the block will fail.
