In short:
I wish Iona’s Bloom effect stays activated after dying.
Long story:
So I was doing the potion quest before fighting first boss and entering Sacra.
I don’t really know if we are supposed to find that cave before first boss, but since I was not able to beat the boss in few tries I thought I missing something in the map in order to level up. (actually it was parrying skill issue)
It was really annoying that Iona’s Bloom effect is disabled after dying, and I was dying a lot there 
I don’t know if that cave is waiting for me again but even if not It would be very practical that Iona’s Bloom effect stays activated until manually deactivated or after passing waterfall and finishing quest as it is now.
