I use Spectacle on plasma to take screenshots. I set a 3 second wait timer on screen caps, specifically for Diablo IV.
Normally It wasn't grabbing my tooltips because mouse or controller would loose focus.
So setting a wait gave me time to just stay on the tooltip and it grabs it fine.
Then can export to something like Gwenview and crop.
These pair well with the snake healing on crit/pulverize/earth magic healing indeed. The shield from overhealing, isn't amazing in itself. But it scales with potion healing %+ paragon nodes if activated.
More importantly, it shields your fortification level. I treat potions as healing for my fortification now -.-
And most importantly, I can chug all the extra healing potions I see to keep the land clean of litter.
Someone needs to deal with all that glass.
