Frenzy charges with Snakebite Assassin's mits

Is there an issue with the use of the gloves where using the skill "frenzy" at max frenzy charges will not refresh the frenzy timer?

When I use the snake bite assassin's mitts I am unable to consistently keep max frenzy charges as when I reach 8 (my max) the duration of frenzy is about 4 seconds (from increased duration), however each subsequent frenzy skill does not refresh the 4 second timer, instead it decreases to 0 where then I will need to build the charges back up.

This only occurs when I have Darkray Vectors dragon scale boots equipped.

10% reduced Frenzy Charge Duration per Frenzy Charge

50% reduced Frenzy Charge Duration

Don't know what level is your Increased Duration gem (or how many passive nodes for increased duration you take)

Do the math; reduced\increased modifiers are additive
Your charges are "destroying" themselves because of the "time penalties" overlap on those uniques

Increased Duration gems don't affect charges.

If you have 36% increased Frenzy Charge duration from the tree, the duration would be 10 seconds * (1 +.36 -.5 - (.1*8)) = 10 * .06 = .6 seconds. If you aren't landing hits faster than once every .6 seconds, you're not hitting fast enough to refresh the charges.

Edit: if you don't have both frenzy duration passives, your frenzy charges expire the instant the 8th one is generated.

I am also using both of these items, I have more than 1 second of charge, (about 3) and can watch it tick down. If I then use the skill frenzy to get another frenzy charge (already at max) the timer doesn't reset as per usual. It flickers at 1 seconds for a visual tick then continues dropping.


I don't believe this is due to the interaction of Dark Ray and Snakebite as I have removed both of these items and see similar things happening (A new charge doesn't refresh the timer, merely holds it at the current time for a visual tick, then allows it to continue dropping)

I am using ROTC so I suspect I'm getting 3-4 frenzy charge "Refreshes" in that time (Which is why i think I see the timer pause.) However the timer does not reset to max.

Using only Snakebite, I've noticed the timer doesn't show the penalty until you reach max frenzy charges. If your max is 3 and you only have 1, the timer shows the full duration as if you weren't wearing Snakebites. When you reach 3 Frenzy charges though, the timer starts reflecting the penalty.
