Culminating Blasphemite bugged? add gem color doesn't change crit %

I have a neck with new color gem, put on or take off, the main panel crit % doesn’t change, there’s no +0.15% per color?

The gem’s bonus adds a cumulative bonus to your critical strike damage, not chance. In the default UI, there is no way to see what this bonus is at. (It may be multiplicative, I honestly don’t know, but either way there’s no way to see it by default.)

add 0.15% to crit damage? so that equivalents to 0.075% the chance?

If additive, the total crit bonus would be 200.6% of the damage of a regular hit. If multiplicative, it would be 201.2%.

There are also only four gem colors; the unique one itself doesn’t count, so if it’s your only gem then you actually don’t get any crit damage bonus.

There are 5 gem colors, though amber is dominantly stamina so we just pretend it doesn’t exist. Also, I’m pretty sure the bonus is additive.

Fair, I had already mentally pretended it doesn’t exist. Oops.

i think depends on crit chance c, average damage is
1+c(1)
if 4 colors so add 0.6%, will be
1+c(1+0.006)
if c=30%, ratio= 1.3018/1.3=1.00138
if c=10%, ratio= 1.1006/1.1=1.00054
so this gem is much weaker compares to if 0.6 is added crit chance

The effect isn’t in any way related to crit chance except it affects the damage of critical strikes when they happen.

Battlecruisr’s post above is correct that the chance is merely additive (resulting in 200.6% damage critical strikes), as I also found that info from the mage discord.

Those crafted Bracers/Waist add an extra 25%.

I honest think it mean, base on how much your crit chance % is adding to 181 stats. same with 2% movespeed. for example, 9% move speed, determine how much 181 stats that go into. so its not like oh im getting 5 gems so i can have 20% movespeed something like that.

Im trying to understand what youre say. So I have a zandalari troll druid with gonk. With 0 gear on and no movement speed buffs selected, I have 105% mvsp. If I equip 1 item with just an elusive blas gem (crit and 2% move speed FOR EACH UNIQUE(it says that on the tooltip) gem. I still have 105%. If I keep that belt on, and equip a ring with a deadly ruby rank 3 which is all crit. I still have 105%. But if I take a belt from BC thats over 200ilvl that has 3 sockets and put 1 elusive gem, and 2 other separate gem colors in it, I get 4%. So to me it seems it only works on 1 piece of gear.
