Armour: as low as possible, I reccomend the factions 15Al cabalist armour, because it's cheap and easy to get.
Weaponry:
Villnar's claw
Villnar's Glove
The attribute points distribution:
12+3+1 Curses
12 protection prayers
3+3 soul reaping
Skill setup:
1:Protective spirit (PS)
For 5-19 seconds, target ally cannot lose more than 10% max health due to damage from a single attack or spell.
2:Spirit bond (SB)
For 8 seconds, whenever target ally takes more than 60 damage from a single attack or spell, that ally is healed for 40-88 health.
3:Spiteful spirit {E} (SS)
For 8-18 seconds, whenever target foe attacks or uses a skill, Spiteful Spirit deals 5-29 shadow damage to that foe and all adjacent foes.
4:Reckless haste (RH)
For 5-17 seconds, target foe and all adjacent foes are hexed with Reckless Haste. While hexed, they attack 25% faster but have a 15-43% chance to miss with attacks..
5:Insidious parasite (IP)
For 8-18 seconds, whenever target foe hits with an attack, you steal 5-17 Health from that foe.
6:Guardian
For 5 seconds, Guardian has a 20-44% chance to "Block" attacks.
7:Balthazars spirit (BS)
While you maintain this "Enchantment", target ally gains adrenaline and Energy after taking damage. (The amount of adrenaline gained increases depending on your rank in Smiting Prayers.)
8:Essence bond (EB)
While you maintain this enchantment, whenever target ally takes physical or elemental damage, you gain 1 energy.
Theory behind the build
Now Protective spirit doesn't prevent Spirit bond from healing you, so you will actually be gaining more health than you will be losing, making the possible number of soloable trolls infinite!!!
The Run
Just sprint past the avicara keeping up PS and SB, the bow attacks might damage you, but just stop sometimes so that the warriors can take a swing at you; healing you.
When you get inside the troll cave, cast PS and SB prior aggroing, and aggro as many trolls as you can get.
REMIND AT ALL TIMES; KEEP UP PS AND SB!!!!
With more than 10 Trolls on your tail you'd be death in the blink of an eye, when your enchants would fail.
Now cast SB, then cast SS (I usually cast RH before SS to power it's effect).
If correctly this shoudl happen without getting interupted.
The next times you cast SS, the trolls will interupt you, so cast guardian before SS.
Now when a single troll is left cast IP on it, to kill it (so you don't have to recast SB which will save you energy)
When you're done don't bother killing the bosses because it is as slow as it is boring; just warp back.
Now I daresay that this is the most easy troll soloing build around there!
