FCR BP question

Hello,


I have a question about FCR breakpoints, basically, if BP 1 is 50, and BP 2 is 60, and I have 55 FCR, (in between the two) do I just have the BP 1 speed, or do I cast 55% faster. Also, same question for attack speed.

I'm certain I could find this in a sticky somewhere, but I have a feeling this is just a quick answer, if not, you don't hafta explain the whole thing, just a simple link to the corresponding sticky would be great.

Thanks in advance

Eleyb

If you don't reach a BP, you get no aditional benifit. In your example 50-59 would be BP1, 60+ would be BP2.

Re: FCR BP question

To elaborate on what stfrn said, Diablo II processes 25 (I think 25, it might be 24) frames per second. To figure out how quickly you will execute the action (casting, blocking, recovering from a hit, etc...) divide 25 (the total number of frames processed in a second) by the frame your breakpoint has put you on.

For example, say you are using a sorceress and you have 20% FCR on. This puts you exactly at the 11 frame FCR breakpoint for a sorceress. Dividing 25 by 11 gives you 2.27. This means that you can cast just over two times every second, because the first cast will take 11 of the 25 frames. The second cast will take another 11 frames, and that will leave you with 3 frames left to start a third cast.

The next breakpoint for a sorceress is 37% FCR. Lets assume you have 40%. This means you are casting at 10 frames. The first cast will take 10 frames, the second will take another ten, and you will have 5 frames left over to start the next cast. This means, at 10 frames, you will cast exactly 2.5 times a second.

Another way of looking at it is you will take .4 seconds to cast a single spell (1 second divided by 2.5=.4 seconds) when you are using a sorceress with 40% FCR.

This is why having 40% doesn't mean that you automatically get 40% faster casting. Yes, you do have more FCR than is needed to hit the 10 frame casting breakpoint, but it will not make you cast any faster than if you only had 37% FCR.

One thing should be noted. This does not factor in spells that are on a timer. I can't say with 100% certainty, but I think spells like that work in this manner: the spells take the same amount of time before they can be cast again, but the actual animation time (the physical action of the character casting the spell) is made quicker by the FCR.

If you are looking for the tables, they can be found here. There is plenty of other information behind that link as well, so I would check it out and bookmark it.

Re: FCR BP question

That's what I figured, I crafted what would be an otherwise very very good necro ammy with 19 fcr, so I can commence being sad now

+34 to Life
+15 to Mana
Regenerate Mana 9%
All Resistances +17
+2 to Necromancer Skill Levels
19% Faster Cast Rate

Thanks a bunch for the info

Re: FCR BP question

It's still an incredible amulet. Necros only need 125% FCR to reach the fastest breakpoint.

For all intents and purposes, it's basically a 15% FCR amulet for a Necromancer--UNLESS they are using a Spirit shield, in which case it could make up the difference for a lower spirit roll.

It's a godly amulet, keep it.

Re: FCR BP question

Considering fcr as a percentage is practically bogus. 100% won't double casting speed, for example. It's actually a number which is fed into a formula with different parameters for the various character classes and produces the casting time in frames (1/25 second). Sorcs and barbs are the fastest casters, zons are the slowest.
