**Preface:**I want to theoretically compare the value of some weapon combinations for barbarians after the 2.0.5 patch. The impetuses for this thread were other recent threads talking about the BK weapon set and Nubtro's Game Mechanics (barbarian) spreadsheet on google docs.

**Bul-Kathos's Set**

After patch 2.0.5, Nubtro reported that, not only can the whirlwind proc from the BK set now critical hit, but also that the damage itself scales with your critical hit damage and chance (before it crits). The damage amount also scales with your attack speed, but because the BK set seems to have an internal cooldown, attack speed doesn't influence the amount of procs.

Your critical hit chance and damage apply twice to the BK whirlwind proc, so bascially those stats are

*squared*when factoring the average damage. The damage is reported as 1950% weapon damage / 6 seconds, or 325% weapon damage / second. This 325% is multiplied by your attacks per second and critical hit/damage, so if you have 1.55 attacks per second, 40% critical chance, and 400% critical damage, you can expect to do:

325% * (1.55) * (1 + .4 + 4) ~= 1310% weapon damage/second in a circular area around your character

However, the BK proc seems to be on an internal cooldown of roughly about 12 seconds (in my personal experience- 2.0.4, so this may have changed). This means that the average damage over time will be about half the active damage/second, or about 655% weapon damage per second. Because of the internal cooldown, attacking multiple targets doesn't really increase the value of the proc.

So the estimated damage of the BK set proc in these circumstances is roughly:

655% weapon damage/secondper target (AoE) -proc coefficient doesn't really matter

**Odyn Son**

According to the information gathered in Nubtro's Barbarian spreadsheet, the reason why the Odyn Son proc seems so powerful is because it apparently scales with critical hit chance, critical hit damage, and attack speed

*twice*.

i.e.: Your attack speed and critical chance/damage values are

*when multiplying the damage of an Odyn son proc.*

*squared*The base damage of the proc is only around 100-120% weapon damage, but the base damage itself is multiplied by your critical hit stats and your attack speed. After this, the damage amount can be a critical hit, which uses your critical stats again, and of course the higher your attack speed, the more procs you can create (thus scaling with attack speed twice as well).

Let's say you have 40% critical chance and 400% critical damage. You also have 1.55 attacks per second and your Odyn Son does 100% weapon damage per hit (3 hits per proc). Each hit of the proc will do 100% * (1.55) * (1 + 0.4 + 4) =403% weapon damage.

*(I think the above calculation is why a lot of people estimate that Odyn Son's proc does about 400% weapon damage. It does about 400% with those values of attack speed, crit damage, and critical chance, but it could do more or less.)*After you get this value, in our case 403%, the proc will hit 3 times, possibly all on the same target. These 403% damage procs can then critical hit again, boosting their damage further (by another 2.6 times in our case, on average), and the faster you attack (and the higher your proc coefficient), the more often you can trigger the proc.

So, say you have a 30% proc rate Odyn Son with the above stats. It does 1209% damage split between 1-3 targets. It will proc 30% of the time on every hit, modified by proc coefficient. Your attack speed dictates the number of proc chances, because there is no internal cooldown, so the damage/second is multiplied by your attacks/second.

This damage is estimated at:

562% (* proc coefficient) weapon damage/secondper target(splitamong 1-3 targets)

Sorry bout title...code 3006. Have been playing the last few hours, got up to get a drink and came back to a DC, but cant log back in, keeps giving code 3006. Reset everything including pc and modem/router still nothing.
