13 > 1 > 11 > 45 > 31
yaaaa
Prays only good if it increases your highest combat skill over what that skill would actually increase it.
ie. 50 str and 31 pray, you got superhuman strength. Superhuman gives 15% str bonus, and that would add 7.5 levels to str (15% of 50) but 31 pray levels would give you [blank] combat levels, while adding 7.5 levels of strength would give you 2 combat levels, with hp.
So just use a calculator and see if you would get more strength or range out of prayer, or leveling.
