I used to farm hydras before the griffon nerf, and i found it to be quite effective.
the build is a standard 55 hp monk build, to farm the hydras outside of augury rock.
I use a Fiery Flame Spitter of Enchanting (20%) and the -50 hp grim cesta.
Here is the attribute point distribution:
12 Fire Mastery
10 Healing Prayers
10 Protection Prayers
12 Divine Favor
Skills:
Protective Spirit
Healing Breeze
Spell Breaker
Flame Burst
Mending
Balthazars Spirit
Blessed Aura
Blessed Signet
Start by casting the enchants, mending, balth spirit, and blessed aura, and use signet to get energy back up. I usually start out going north-east to take out those hydras. Cast protective spirit and spellbreaker, and grab as much aggro as you can get. I dont cast healing breeze until I stop after i have aggro. With Spellbreaker on, they wont be casting meteor, which is the main reason i choose to bring it. Spam Flame Burst, along with renewing protective spirit and healing breeze when needed. Energy shouldnt be a problem because balthazars spirit, but if it is then use blessed signet.
Thats basically it, the drops arent amazing, but i do get the occasional gold.
I used to farm this with SS, but i found that by using SB, it makes it easier and flame burst is more effective.
Have fun and good luck!
