mokey if you want to train prayer
You don't need armour to train prayer, it's only burying bones. If you want to train combat with prayer bonuses though, the best f2p stuff to wear is monk robes, a holy symbol, an explorers ring, and a mace (corrupt dragon is the best, but it only lasts 30 minutes, so use rune if you can).
if you plan on getting melee up, then yes, but it is VERY useful to have 44 prayer, (for anti-pjing, monster killing, increased max hits, etc)
Prayer is considered by some to be the hardest skill to train in F2P worlds. It takes money, patience, and effort.
