@raychen: A 50% chance means that for every time you try to hit, it calculates and have a 1 in 2 chance. So if you're unlucky, you're 5 times in the part where it dodges. Statistickly, when you have 100 attack, then you'll have 50 hits and 50 misses. There can even be that someone hits 10 times in a row but then takes a hit 15 times in a row
