Did a little research and came up with this (Retouched by Nemisari for clarity):
105/55 is health
With 5 supirior runes your health goes to 105, and with a -50 health focus item you get down to 55 hp
Since protective bond causes you to loose 5% of your health, 5% of 55 causes you to only loose 2 hp, Mending and Healing Breeze heal you faster than you take damage, so you dont loose any health
Mo/W
16 prot prayer
13 Healing Prayers
rest in smiting
Get the -50 health Icon from the quest in Ascalon city,"Cities of Ascalon"
Get the +1 prot Icon outside Bloodstone Fen from the collector with 5 mountain troll tusks
Smiting rod from the collector in Droknars with 5 Stone Summit Badges
any armor will do but a +1 Protection scalp piece is a must
1 sup smiting rune
1 Sup Healing
1 sup Divine
1 Sup prot
1 Sup of your choice (not vigor)
Healing Breeze
Balth. Aura
Balth. Spirit
Mending
Essence Bond
Prot. Bond
Zealots Fire
Bonnetis Def.
Equip Prot. Icon and cast Prot Bond till you get -1
[updated: now minimum energy loss is -3 since the nerf] energy from dmg then switch to -50 health icon and smiting rod and cast other Enchants: Mending, Essence Bond and Balthazar's Spirit
Respec to 16 Smiting Prayers
Keep Balthazar's Aura up
Cast Zealot's Fire before it runs out (60sec timer)
use Bonetti's Defense as soon as it's lit (while Zealot's Fire is up)
if health starts to drop, use Healing Breeze
Balthazar's Spirit will keep your energy up and keep Bonetti's Defense lit up
Bonetti's Defense will block attacks 75% of the time, give you 5e for each block, and set off Zealot's Fire
it's recommended you keep 5 enemies on you to keep up adrenalin and energy, but no more than 10 in the underworld
