Attack speed calculation & PD with zerk

[reckoner]

The attack speed for each hero is expressed as a number

that represents the delay between attacks, in milliseconds.

For example, PD's base attack speed is 1000, which is

1 second per attack. SK's base attack speed is 600,

or 0.6secs per attack.

All attack speeds are rounded up to the nearest 200ms,

after any speed-boosting effects.

To calculate an increase in attack speed, add 1 to the

percentage increase, and divide it into the hero's base

attack speed. Repeat as needed for multiple attack speed

boosts. Then, round up to the nearest 200ms.

Example 1: PD attack speed, with Blitz 5...

Blitz 5 = 30%

1000 / 1.30 = 769.23

round up to the nearest 200ms...

PD attack speed = 800

Example 2: PD attack speed, with Blitz 5 after 1 PD proc...

assume PD has 9/10 skill, which is 50%

1000 / 1.30 / 1.50 = 512.82 ==> 600

You can calculate the attack speed for any hero using

these calculations.

For those people with a PD that has Berzerk 5+, the next

question is... how much should zerk be upgraded? Here's

some tables that show PD attack speeds, with varying

PD skill levels and varying numbers of PD stacks. The

first table shows these attack speeds with the Blitz 5

artifact on PD, and the second table is without Blitz.

You can see from the first table, that upgrading zerk

past 5 has only a minimal effect on PD's attack speed.

If your PD has skill 9/10 or higher, zerk 5, 6, or 7 

behave identically, and only zerk 8 will help you, on

the 2nd stack of PD's proc, if it has skill 10/10.

In my opinion, you should either get your zerk 5 PD

to skill 9/10, or keep it at skill 8/10 and upgrade zerk

to 6. It's just a question of whether you want to spend

the fames or the shards. After this, any further

upgrades of the skill, or zerk, won't help at all until

you get the skill to 10/10 and zerk up to 8.
