If you're looking to inflict the biggest wreak on your opponents, mage is likely to be the type you should select. Apart from their destructive abilities, however they also possess amazing crowd control skills OSRS gold (such such as Polymorph) as well as support abilities (such like summonable meals or the ability to teleport).
As mage, you'll have to select a single talent tree and stick to it. You can pick from ice, fire, and arcane specificizations. You can choose any spell you want from any tree but your points are most effective when you focus on one tree and pour all those points in it. It's tempting to distribute your points across the lower-level talents and become an expert in all things but you'll hinder your ability to access the most potent later talents if make the mistake of doing this.
They're well-known for being adept at soloing, primarily because they can deal damage to enemies from the distance, but then slow them down or firmly hold them in place, while retreating, repeating the procedure until the target is dead. It is possible to deal the most damage for each second of other class, however you're likely to consume your mana extremely quickly if don't be sure to pace yourself, which could necessitate drinking quite often. Also, as mentioned earlier, you're vulnerable particularly if your enemies are in a position to attack your character, since the majority of your spells can be broken if you're hit as you're casting them. However, there are exceptions to this rule, and some abilities can aid in making specific spells more resistant to interruption, however, it's still important to keep your enemies as far from you as much as is possible. You can achieve this by slowing the enemies (e.g. by using Frost Bolt) or rooting them (Frost Nova) however, you'll need be wary of opponents with high resistances as if you Frost Nova gets resisted, it'll take a long time for it to recharge.
Luckily, you can use a powerful polymorph spell to manage crowds which is easily cast on an add, as that no more than one person is fighting against you. (If two or more players are attacking you, however it's best to just run and nova.) Frost armor can also assist in the event that you need to flee, as it's designed to Buy OSRS gold slow down any person who strikes you. This is assuming that the mob does not resist it, which is of course, and it will do if they're two levels higher than you.
