We suggest having at least 80/80/80 in your combat stats and 70+ range to be able to wear a full blessed d’hide set.
70+ prayer is also recommended to use piety.
For combat training, you can use our progressive hill giant script. It will start from level 1 and we suggest to train your combat in f2p, up until you reach 60/60/60 in your stats. If you use the bury bones option, you will achieve 43 prayer on the way too. At 60/60/60 switch to elder chaos druids or sand crabs or any other training method that you prefer and aim for 80/80/80.
