In the moment, the most prestigious level is level 90. Don't be hesitant in the slightest and OSRS gold go on and buy drygore mace. Personally I've saved around 100M, from scratch, to purchase a Drygore mace and it's been a massive improvement. The Drygore mace, to my mind, is the top choice because of two reasons- the first is that it's marginally cheaper than the Rapier or Longsword and the second reason is that it has a +9 prayer bonus.
Another thing that you need to know is Combat Triangle Combat Triangle will be ULTIMATE today. It's hugely different the gear you use and what style of attack you employ, and so on. Monsters generally have one specific weakness and, if you utilize their unique attack style that's also fairly efficient.
That being said it is important to recognize that this weakness is somewhat general. Fire Giants, for example have a weakness when it comes to Slash attacks. This means that melee is highly effective against them, and they're extremely weak against slash attacks- but crush and stab work fine. However it's difficult to the targets with mage.
The same applies to your character. You cannot engage in melee while wearing d'hide. To illustrate how awful this is, the stats are somewhat like the following: wearing a ranged top and bottom as well as helm when fighting reduces your accuracy by 27%. The use of a ranged top and bottom as well as a helm while engaging in meleeing will reduce your accuracy by 45 percent. Gloves and boots don't appear to be a big factor though.
The two last points show you how to be able to exploit the weakness of monsters. If you're facing Dark Beasts (which mage you now), and show a weakness to range, and you decide to melee and you'll be able to cheap RS gold notice two things. One is that you barely get hit.
