Extremes will give you about a 5% increase over supers at your stats. Turmoil will give you about an increase over piety of about 7.5%. On a slayer task it will give you an increase over piety of about 6.5%. Either way turmoil is more effective than extremes. -- Now, you probably don't use prayer on slayer tasks, but let me give you a run down of why it's a good use of your money. Assumptions: You don't cannon and turmoil will not affect your accuracy (it does, but it makes things harder to calculate). 1 hour of turmoil at 95 prayer costs 90k, wearing proselyte chest and verac's skirt (only 115k/hour if you wear bandos lol). But for every one hour you turmoil, you gain a free 0.32 hours of combat and slayer xp, charms, and drops. JUST looking at the combat and slayer xp, 0.32 hours saved could be 0.32 hours of picking mort fungus (a pretty bad method), which would save you 250k! That more than pays for the turmoil. Other benefits: More accuracy More charms More xp Access spirit mages, abyssal demons, strykewyrms sooner = more profit More defence Big numbers :^_^:
