Bloodborne - All Main/DLC/Chalice Bossfights, NG+, BL4, No Items, No Damage, No HUD

All bosses, done at Bloodlevel 4 in NG+ without the use of any consumable items, no Caryll Runes, no taking damage, no HUD visible. I allow the use of guns.
NG+ does not affect Chalice Dungeon bosses.
For Bloodgems I mainly use Poorman Gems (Phys. UP near death).
The first 4 bosses, as well as the Pthumeru, Central Pthumeru and Hintertomb Chalices are done with much weaker Phys. UP Bloodgems.
Against Kin-type bosses like Ebrietas, I use Bolt Gems.
During the first three bosses my weapon was at risk, so I was dealing only about half the normal damage. This was not intentional and it led to Gascoigne being the hardest fight for this challenge.
The no damage constraint requires specific tactics during the Micolash fight (can't take fall damage) and the Ebrietas fight (can't melee her during 2nd phase).
