High level alchemy (sometimes refered to as alching or HA) is a level 55 magic spell that converts items into coins (gold/gp). It works in the same way as level 41 magic low level alchemy but gives a higher financial reward of 60% of the speciality shop value compared to low level alchemy's 40%. Even if not taking the time to maximise profits high level alchemy can still be used as a great magic training method at low to mid levels. It's also a good method in F2P and for ironmans to make money from their general skill training. Because of the ability to alch from a noted stack you can train very quickly without the need to be near/use a bank, if just doing this method with a noted stack you can generate nearly 80k magic xp/hr. Profits will of course vary lots although there are always some high buy limit items that will almost always be break even or slight profit with high level alchemy.
Gargoyles are combat level 111 monsters located in the basement and top floor of the Slayer Tower, north-west of Canifis. They require level 75 slayer level to be harmed and the gargoyles in the basement can only be fought on a slayer task. Unlike normal enemies, and similar to a earlier slayer task enemy the rock slug, they cannot be defeated unless you have either a rockhammer, a rock thrownhammer or a granite hammer to deal the final blow once they are below 10 hp. Unless you have the gargoyle smasher perk, purchasable from Slayer masters for 120 Slayer points you will have to use your rock/ granite based weapon on the gargoyles to defeat them. In this guide I will cover best techniques for fighting them as a slayer task, and also cover their use a decent/ passive money maker.
Blackjacking is one of the fastest thieving methods in OSRS, possible from level 45 thieving, you can gain up to 250k xp/hr. It works by knocking out bandits and thugs and then pickpocketing them whilst they are unconscious. In this guide I will cover a method that exploits having a constantly full inventory of coins and food/ food residue to avoid being unnecessarily stunned. You can blackjack until level 99 although at thieving level 91 Pyramid Plunder becomes a faster method. Blackjacking extremely click intensive and takes precision and practice to gain the optimum speeds.
