Just ran DS on my mage. Got assigned to bounce orbs.
It flattened me instantly. Cauterize went off but did nothing.
Cauterize text says “Any damage that would otherwise kill you reduces you to 50% health” - which implies you should not be able to suffer a oneshot kill.
Clearly, this is either a lie or there is a bug.
cauterize is capped, if you take more than 200% of your health, you die
that is not mentioned in the tooltip… but that would explain it.
Did this change with prepatch?
yes, its a mop change, but you can soak with greater invis talent instead
I just reread greater invis. Nice. Ty for the tip 
will try that out next week.
