New Follower System - Cooldown Reduction from Gear TESTED

General Discussion
1

Since there was almost no information from Blizzard regarding how Cooldown Reduction (CDR) works in the new follower system, I decided to do some experimenting to better understand how CDR works on followers.

First, the information already discovered amongst the community:

  • The only follower that benefits from gear based CDR is the Templar
  • The only Templar skill that benefits from gear based CDR is the Templar’s Heal ability

I could not find any information on how the cooldown of Heal is actually affected, so I experimented myself. I tested this with a templar wearing an immortal relic, and I geared the templar with varying amounts of CDR gear from 50% to 100% CDR. I allowed T16 mobs to drop my health below 50%, which is usually when a 25k strength Templar will cast heal. As soon as Templar Heal was cast AND the health on my globe ticked up, I started a stop watch. I then took 50% or greater damage ASAP, and then ran around the area until another Heal cast registered, and I stopped the clock once the heal registered.

These are the results:

  • At 50% gear CDR, Heal’s CD is reduced by approximately 40% to 18 seconds
    • A 10% offset from expected vs actual
  • At 66% gear CDR, Heal’s CD is reduced by approx. 50% to 15 seconds
    • A 16% offset from expected vs actual
  • At 100% gear CDR, Heal’s CD is reduced by approx. 66% to 10 seconds
    • A 33% offset from expected to actual

While I did not keep track of the data between 66% and 100% CDR gear, I did test it, and can confirm that the effective CD of Heal did decrease between these CDR points.

The relationship between Heal CD Time in seconds as a function of Bonus %CDR from gear seems to follow an inverse square curve, with 10 seconds being the lower boundary at 100% bonus CDR.

I also performed a 100% gear CDR test using a 50% all-skill CDR relic, to see if there was any benefit. This further reduced the CD of the Heal ability to approximately 5 seconds. This is a 66% CDR from the already 15 second Heal CD while using the relic, and confirms the data from the previous tests.

If you are playing a glass canon class solo, the benefit of Templar heal is substantial. At 25,000 strength, the Templar’s Heal ability heals for about 425k health. If you are able to get that every 5 or 10 seconds, especially when running with something like a squirts necklace where you are likely to suffer massive damage up front, rather than spaced over time, being able to immediately rebound from that damage consistently can make your GRifts a lot smoother. I use this for my GoD demon hunter.

Hope this helps.

Blizzard, PLEASE ADD WEIGHTED, REAL VALUE CDR TO THE FOLLOWER STATS PAGE SO THAT WE CAN JUST SEE THIS INFORMATION WITHOUT HAVING TO SEARCH THE INTERNET FOR IT, OR SPEND OUR TIME DOING PLAYTESTS ON A NON-PTR VERSION OF THE GAME.

EDIT PER NEW INFORMATION FROM IRIA

The information regarding my posturized “relationship” above is negatable, per the exact formula provided by user Iria in the comments. You may use this information to calculate your own exact CDR% based on equipped gear so you will know what to expect from your follower heal.

That being said, from what I have found in gearing Templar, maximum CDR from gear is 103%. This would include a 100% bonus Leoric’s Crown with Flawless royal diamond, max 8% CDR necklace, rings, gloves and shield, max 10% weapon, and 20% from 2 pc Captain Crimson’s Trimmings.

Following that formula with the above mentioned pieces yields a maximum effective CDR of 67.3% to your Templar’s Heal. Near equal to the approximate 66% I provided for 100% gear-CDR above.

Thank you to Iria for clarification!

Hope this helps,
Karn

Wow! Thanks for putting in the effort to test this! It’s a bit of a shame that the only skill affected by CDR is the Templar Heal, but thanks for the info.

I was pretty disappointed in that, but it would prob be way too broken to make it so everything could be reduced with gear. It would completely trivialize the 50% relics.

Still, having increased rates of 425k heals is very strong for solo squishy builds, imo.

It makes more sense to use the 50% relic and good survivability gear up to GR120-130, but after that when you need immortality to keep the follower alive, CDR gear on a templar is pretty dang stronk.

Templar is an underrated follower. When you are pushing high and prone to death, he does make a real difference.

Oh yeah, my templar is pumped with CDR, he’s a quick and professional healer. :stuck_out_tongue:

CDR does NOT affect the cooldown of the follower cheat death skill, which is a good thing.

lol i neeeeeeed that shid on my hardcore GoD DH

Cooldown reduction doesn’t stack like that. You need to combine the individual pieces with a reduction formula. For example, 10 pieces of gear with 10% CDR each combines to ~65% CDR whereas 5 pieces of gear with 20% CDR each combines to ~67% CDR.

Again, CDR follows a reduction formula and the individual amounts matter. Please list the individual CDR amounts on each item and compute the following:

Total CDR = 1 - (1 - CDR1)*(1 - CDR2)*…

where CDR1, CDR2, etc. are the decimal values on the individual items like 0.125 for a Flawless Royal Diamond in the helm.

All reductions are multiplicative, not additive.

Interesting. I was unaware of an exact formula existing for this. My testing and data was never supposed to be exact, just approximation. Still, the 100% CDR limit of my approximate data would be mostly accurate because the absolute ceiling of CDR you can put on the follower is 103%

I think that’s not how Cooldown reduction stacks, it stacks multiplicatively; not additively.
If you have 20% CdR from one gear and another 20% CdR from another then it’s [.2 + (1-0.2)*0.2] = 0.36 = 36% cooldown reduction, not 40%. If you don’t believe us, give them a 50% cooldown reduction token, and scribble down your findings.

Great findings Karn :+1: No reason to nitpick about the CDR when it’s obvious what is meant - and there is no CDR info on the Templar sheet like we have on our own details sheet.

Thank you for your input everyone. I was unaware of an exact formula and actually could have saved myself a bunch of time doing this play testing if I’d known earlier. I edited the original post to include Iria’s explanation of the formula and a more exact estimate of the maximum CDR for follower’s.

No problem, basically all reduction formulas follow the same idea.

For example, 10% CDR + 20% CDR = 28% total CDR. The first item reduces the cooldown by 10% so 100% goes to 90%; the next item reduces the cooldown by 20% on the remaining 90% so 90% goes to 72%. Thus the total cooldown reduction is 28%. Also, the order doesn’t matter since scalar multiplication is commutative.

Other things that use this reduction formula are resource cost reduction and damage reductions (e.g. melee, ranged, elite, etc.).

14

Multiplicative damage reductions - do those only apply to the secondary reductions from gear (i.e. excluding the baseline reductions from Armor and Resistances)?

15

7-11% elite/ranged/melee damage reduction will not be directly added to the mitigation percent but stand as a layer to reduce specific attacks. Think it as a different layer for damage reduction just like block amount or absorb.

Read about damage mitigation in maxroll gg site:

It’s not nitpicking if it’s helpful advice.

17

Karn came up with something nobody else have tested, namely how much an additive amount of cdr on the templar can reduce the cool down of his healing skill. And since we don’t see the effective cdr on his skill sheet Karn’s numbers are quite useful.

18

We already knew this, though. Also, as someone mentioned, Templar Heal is the only Follower skill actually reduced by CDR. I am pretty sure the Templar CDR formula is the same for the player formula, it just only works for one skill from one follower.

19

Not to drag the discussion on but even though it is well known I’ve never seen the numbers presented before like Karn does.

There is no need to publish numbers, though. You can work it out yourself.
