Making potions with Prescription goggles and an Alchemist's amulet: Defence

Method guide

Defence potions temporarily increase the player's Defence level by 10% plus 3, improving resistance to incoming attacks. This variant combines Ranarr potion (unf) with white berries. It assumes that Prescription goggles and a charged Alchemist's amulet are worn. No separate Amulet of chemistry is worn, and the amulet's charges are loaded before the session begins. Prescription goggles have a 10% chance to prevent the secondary ingredients from being consumed. The primary potion or base ingredient is always consumed normally. This variant would normally consume 1,960 secondary ingredients per hour. With the goggles, the expected consumption is 1,764, saving approximately 196 secondary ingredients per hour. For each eligible potion, the Alchemist's amulet has a 15% chance to produce a four-dose potion instead of the standard three-dose potion. The effect can apply during the same action in which the Prescription goggles save the secondary ingredient. The extra dose does not grant additional Herblore experience. At approximately 1,960 potion-making actions per hour, the expected result is 294 four-dose activations and 1,666 normal three-dose potions. This produces 6,174 total doses, equivalent to 1,543.5 four-dose potions. The output quantity is rounded to 1,544 four-dose potions per hour. One stored charge is consumed whenever the Alchemist's amulet activates. Each Amulet of chemistry supplies 10 charges. The expected hourly consumption is 294 charges, equivalent to 29.4 Amulets of chemistry. The input is rounded up to 30 so enough charges are loaded before the session. Both equipment effects are passive and require no additional clicks during production. The click intensity, action speed, afkiness, and Herblore experience rate remain unchanged. Players can make 14 potions per inventory by withdrawing 14 unfinished potions and 14 secondary ingredients. Each potion takes 1.2 seconds, or 2 game ticks, to make. A full inventory of 14 potions takes 16.8 seconds, or 28 game ticks. Actions per cycle: - Use the unfinished potion on the secondary ingredient: 3.5 seconds. - Make 14 finished potions: 16.8 seconds. - Restock the inventory: 5.4 seconds. Total time per cycle: 25.7 seconds. Approximately 1,960 potions per hour.
