Looking for some suggestions for hats. Anything tradeable with better hp/mana than a Bellows Crafted Cap or Platinum Tiara? I can't seem to find one.

White Dragon Helm
AC: 22
STR: +10 DEX: +15 STA: +12 HP: +100
MANA: +60 SV FIRE: +10 SV DISEASE: +10 SV COLD: +10
SV MAGIC: +30 SV POISON: +10

would cost an arm and a leg tho, if you can find a seller

Helm of Nocturnal Phantasms?

Little upgrade, but it's truly ugly to wear :p
