Off-Hand Stat Stick Mechanic Questions

HI

Currently playing a Sunder Glad w/ Prismatic Eclipse as my offhand w/ 3 green sockets.

i understand that sunder will only attack with main hand and benefit from offhand stats like PE's 36% attack speed. I'm at the point where I'm looking for a stat stick upgrade and I don't entirely understand what stats can be applied to sunder.

My assumptions are below and correct me if i'm wrong please.



An items base stats (example: a claw with 2% phys leech or a sceptre with elem pen) DOES apply while an items physical damage does not apply correct?

stats like Gain X% physical damage as extra (whatever element) does apply

attack speed on an item does not apply unless its global attack speed?

Gain bleed chance or bleed damage would not apply correct?


thank you in advance for any info
