Impale Physical Mastery doesn't work (?)

Upon allocating Physical Mastery 20% Impale, the impale chance doesn't increase. It works for Sword Mastery, but not Physical Mastery?

I have 57% From the following:
Merciless Skewering - 15%
Impale Chance - 10%
Impale Chance and Physical Attack Damage - 5%
Sword Mastery - 20%
Jewel - 7%
57

Can confirm the same thing, different Physical Mastery cluster but same behaviour:

Character sheet shows 80% for my Shield Crush with:
Merciless Skewering - 15%
Small Node leading to Merciless Skewering - 5%
Physical Mastery - 20%
Impale support gem - 60%

Should be 100% but sheet shows 80%. Regular attack only shows 20%.
Unallocating mastery makes the number stay the same - 80% for Shield Crush and 20% for regular attack

I also encountered this problem.

I also have this issue. I spent a respec point to see if the chance would change, and it didn't make a difference.

Me too. 60 impale on gem 20 on tree and 20 from mastery gets me 80 tooltip. Burned a regret to confirm impale chance under physical mastery not showing up on tooltip.

-O

i posted this issue since the first hour of the launch.Lets wait for the hot fix

I have same problem, but checked - with 0 chance to impale on tooltip and phys mastery taken i still impale monsters. So i think this is pure visual bug.

Same problem and still didnt fix that...(
