Summary of bottom few paragraphs maxed character pietying his slayer tasks 92k combat xp/h, 24k summoning xp worth of charms, and 134k profit. Yes, I did say profiting while pietying. Armoured zombies. 110k combat xp/hour. take your pick between the two. Read on for all the information on how I got these rates. Hm.... well isn't this odd..... I've analyzed this same question myself for many weeks. Personally, I wear proselyte and use the piety prayer on the majority of my slayer tasks. The slowest experience task I get would have to be dark beasts, as not only are they single combat, but they have a noticeable defence level. I get 93k attack experience an hour, sometimes varying 1k either way. These numbers are self measured. I do not wish to throw anything off. For argument purposes I will say 90k. My fastest task, mutated bloodvelds, are much better. I do not use a cannon for them, but I consistently manage to get 110k attack experience an hour on top of 30k range experience from my steel titan. The way my tasks are arranged, I pick up slightly more summoning experience worth of charms than I do in slayer experience. For argument purposes I will mark them as the same. Pietying, I would mark slayer as having an average of 92k basic combat experience an hour. This is averaging all slow and quick tasks out as well as taking banking time into account. So, slayer trains at approximately 23k experience per hour while pietying. This is assuming higher leveled task brackets, where the majority of training takes place. It also assumes skipping about 30-35% of tasks that are slow, such as wyverns, certain dragons, etc. Now, for the drops. I maintained a separate tab for all drops I received from level 98 to 99, approximately 1.23m slayer experience worth of training. Excluding the slayer darts that I cashed in, I sold 13m from drops. Among this, there were 3 whips and 2 dark bows. The drops from slayer work out to approximately 10 gp per experience, at least in the +85 region where the majority of training to 99 takes place. Now, these drops must have the costs to obtain them subtracted. (45*15 + 4*75 + 225)/50=24 This represents the average number of points rewarded per task in a 50 task cycle. 24. Skipping 1/3 of tasks, a person keeps approximately 55% of the points that they earn. This equates to 16 points per task kept. 2.2 tasks per 250 casts of slayer dart. 250 casts is approximately 70k in value, so the slayer point bonuses alone cause a person to profit 32k per task. I did not include that in my earlier analysis, but I will add that in there now. From 85 to 99 I completed 312 tasks. 9.8 million divided by 312 = 31.4k slayer experience per task. As the 23k slayer xp/hour rate has already been chosen, it takes 1.36 hours to finish each task. The slayer points add an additional 24k in profits per hour. 1,230,000 / 23,000 = 53.48 53.48*24000= 1,300,000. I profited 1.3 million from slayer points in that one level Add this into the drops. 13.3 million earned from a single level. But wait, I said that I was pietying earlier, didn't I? This is true, and it isn't cheap. This is how the calculations play out. Wearing proselyte, a fire cape, and a fury amulet as my full prayer boosters, I was able to cut usage down to 12 3 dose prayer potions per hour. This is taking into account the home teleport between tasks to charge my prayer, and the time spent in a bank not using any. In pure usage I would use 14 prayer potions in an hour. Increase this average to 15 potions per hour to account for tasks in which I pray on. I also use 3 super set(3)s per hour, redosing each 6 minutes. A super set is 3.7k for a 3 dose set, so an additional 11k. 15 prayer potions at 6.1k each is 91.5k. A person slaying with my method spends 102k per hour to increase their slaying speed. With 10 gp/xp, 23k xp/h, and the 24k gp/h bonus due to points, 254kgp/hour is the total loot. Subtract 102k/hour as well as 20k/hour for steel titan scrolls, and 134k gp/hour is the total profit while speed slaying. Now, your numbers vs. mine 110k xp/hour at zombies 92k xp/hour slaying, as well as getting 24k xp/h worth of charms and 134k gp/hour slaying. If you haven't realized it by now, yes, I do profit while pietying. All those rune chains and boots and runes more than pay off. To clarify further, much of this slaying methodology is self invented. I popularized the chaos tunnel dagannoths among many slayers personally. I also popularized the Zamorak brew as well. I have changed many facets of slayer. If your single goal is to become maxed in melee, then zombies are your best bet. If you are a higher level character interested in many facets of playing, eg. summoning, combat level, money, etc, then slayer is your best bet. Speed slaying is specifically endorsed by me. I would say that Computer's numbers are skewed because of his lower slayer level. I have trained slayer with Duradel from a lower level, and I can also attest that he gave many unsavory tasks. However, this brief period of slowness is only a small part of the whole should you continue. 75% of the experience from 1-99 occurs beyond 85. I will agree with an earlier quote. You either love Slayer, or love to hate it.
