Splash technique is used by a lot of RuneScape players to RuneScape gold increase their Magic even while going off the rails, since it's like cutting a Yew log. It is not necessary to pay much at all to the screen, as rats around Lumbridge castle aren't able to cause damage. The only thing you need to do is to press something on the screen or move the camera every 20 minutes so that the game won't shut you down.
How to start splash training? You will need to change your gear setup and remove all bonus magic items, including your Magic Strength so that you have negative magic statistics. For this, you have to have one of two sets of the equipment that are listed below. You'll need to equip your plate set that includes a kite shield as well as Green dragonhide vambraces (-10 Magic) or Cursed Goblin Staff.
It is possible to raise your Ranged level to level 40 and equipping vambraces offers players the chance to equip one of the staves that are elemental. This saves a lot of runes but if you don't wish to increase your Ranged and you're able to paying more for it, Cursed Goblin Staff will be enough. The table below shows the range of exp needed to reach the level of.
Be aware that this method is usually very slow and time is needed. For instance, achieving up to 99 with just Fire Strike could take roughly 1,000 hours (almost 42 days!). There is a reason why the lack of YouTube videos that discuss how to use splash magic. This is exactly why this method is recommended only to beginners and those who are able to buy RS gold fake a lot.
