Can someone do some calculations to see if using the berserker prayer saves enough cost in pure extreme sets compared to the extra cost in prayer?

I'll give it a shot:

 

Assume a player has 99 in the stat to be boosted and no prayer bonus is present. Let's also assume that the player has 99 prayer to maximize efficiency of prayer potions.

 

For an extreme atk, def, str potion, you will be boosted 26 levels to 125. Boosted stats drop at a rate of roughly 1 per minute iirc, so that's 26 minutes.

 

Berserker extends the duration by 15% or 3.9 minutes if it is left on the entire time of the boost before returning to normal stats. You will consume 99-100 prayer points in this time, which is a little more than a full prayer potion which costs 11k.

 

Each dose of an ext attack is about 2.8k, 6k for ext str, and 4.2k for ext def. Since you're gaining 15%, it's 420, 900, and 630gp per dose to you.

 

I'm not sure if these calculations are really correct, but on the surface it seems like it's not worth using. However, I haven't factored in prayer bonus or how some people pot up before returning to normal stats. There are also other considerations like you being able to fight at higher levels longer.

Since I assume this would apply to Slayer, since in bosses you aren't praying 100% of the time anyway (respawns). You don't give me a lot to work with so don't complain.

For a prayer bonus of +19. While using berserker, your prayer will drain 1 point per 29.97 seconds, or 2.002 points per minute. Assume the player has 70 prayer and is carrying a holy wrench. The player would get 25 prayer points per dose of prayer potion. The player would use 0.08008 prayer potions per minute, or 715 coins per minute.

 

Assuming the player is using extreme potions at level 99 attack and strength. One dose of each costs the player 8648 coins.

 

Let the player repot when his stats have fallen n. Each minute, the extreme potions cost 8648/n without berserker or 7520/n with berserker. But the prayer potions increase the cost of berserker by 715 as found before, making the cost per minute of berserker (7520/n + 715).

 

If (7520/n + 715) < (8648/n), then berserker is worth using. This is true when n<1.75. So basically, unless you're repotting every other minute, it's not worth it to use berserker.

 

We can reevaluate this assuming 99 prayer. The player would get 32 points per dose which comes to 558 coins per minute.

 

If (7520/n + 558) < (8648/n), then berserker is worth using. This is true when n<2.02. So basically, unless you're repotting every other minute, it's not worth it to use berserker.

 

It is probably never worth it to use berserker with extremes.
