Can someone explain to me how the dice rolls work?

[Chest_Rockfield]

If I have 229% attack chance and the monster has 40% block chance, shouldn't that work out to a guaranteed hit?

[Rory Mac]

Maybe to keep it interesting there is a 90% cap or something like that??? I'd be interested in hearing the programmers comment cause I was thinking like you that once I got my AC up to 200% or so that I would never miss.

The way that I figured that it worked was that you got your attack chance by subtracting the enemies block chance from your attack chance, so if you had a 200% attack chance and the enemy had a 90% clock chance, the attack chance would be 110%... but from personal experience this is not the case. As Roy Mac said, I would also like to hear from one of the programmers as to how this is calculated.

You will !never! reach 100% hit chance.

Thank you, I think I get it now. According to the graph, one should stop trying to build upon the attack chance after a certain point, as it will only actually improve your chance by a smaller and smaller amount each time, as the graph approaches the unreachable 100% attack chance.

EDIT-So if you do happen to reach the 100% hit chance, what would the formula kick it back down to... (I'm not great with calculus and trig...)?

EDIT: When clicking on the link to the graph it appears to delete the equal sign as well as all parenthesis, you will need to manually copy and paste the equation.

F = 50 * (1 + (2/pi) * ATAN( (C - 50) / 40 ) )

One VERY important thing to note, the graph that you see plotted is based on the DIFFERENCE between your attack chance and your targets block chance. This means that if your attacking a mob with only 50 defense and you have 150 attack chance you won't see a huge difference by adding an additional 5 AC. however if you have 150 attack chance and your target has 150 block chance adding 5 AC could make a very BIG difference. So don't just assume that a high AC means your home free, the point is that you need to stay *ahead* of your targets block by a certain amount in order to be the most efficient.

Also for the above, there is no "knockback" on the chance, it's a smooth curve that levels out as you add more disparity between attack and block chances.

OMG! Thanks Samuel! I have been wondering how the damage/attack was determined.

I had a worthwhile post!!!

The above post here is great! Thank you for this number chart to show actual AC after the formula is calculated.
