Just to explain a little further, the monster has to check for you and not be able to find you in order for you to be erased from its hate list. If you're two-boxing you can just have both characters in transit between fluxes at the same time, and your monster will go idle.
It generally takes 2 "magic skill" to equal 1 magic accuracy right?

i'm levelling monk solely for Bhaf2, and I have a question on Impetus
does it reset on every miss, or only if you fully miss an attack round?
Only curious, this isnt going to be a career change. although it might retire my ninja.
it resets after an attack round.
To clarify, it resets after an attack round if you missed any hit in that round.
Is Ker's Cuirass good for anything on any job? Picked it up whilst spamming AR2 for umbrage plans (I don't care for Drg enough to farm 35 more plans for an idle body piece, and I doubt I'll be doing any more salvage after finishing Skadi+1 hands and feet for any other ker/ares stuff)
CDC on PLD if you don't have Twilight/Kareiyh is the only thing I can think of.
The any TP sets floating around that could use it for war or drg you think?
I see delve armor. like 'Bokwus Circlet' can be sent within PoL acct.
Can it still be sent if it's augmented? and does it keep the augment?
Unless something has changed, nothing with "Aug" tag can be sent or stored.
I've seen some sets for DRG that use it, such as this one.
