ive entered the planar sphere but i cant destroy the clay golem what weapon/s make this possible cus i heard there immune to magic ?

You need enchanted blunt weapons. Staffs, warhamers, flails, clubs, that sort of thing.

If you must use magic, two or three castings of Lower Resistance will bring down the magic resistance to a semi-reasonable level, but you probably dont have that spell yet.

cheers if anyone else is havin trouble killin a clay golem summon an air elemental these things waste caly golems easliy

Air elementals waste all golems. lol
