Two days i decided to give 55hp a chance as well, so i bought new armor and collected all stuff/skills needed (according to wiki). The only thing i still needed was the -20 cesta, in case you have 15% dp.
Today i decided to play a bit barrage in FOW... in one of the chest i found a nice healing ankh:
energy+12 (req 8 healing)
armor +5 (always)
health -20
Correct me when i am wrong but i think this is probably the best -20 focus i can get??

Now that i have this i start to wonder a few things:
* Has anyone ever seen a -50 variant on this? Does it even exist?
* Is it possible to get to 55hp using a certain weapon in combination with this ankh? Maybe a pre-searing weapon that gives -30hp and hopefully also extra energy and +20% enchantments (if modable). Or is that wishful thinking?
Sorry if this has been brought up before. I tried to search the forums but i always ended up with tons of useless results...
