## The picture.

Are people allowed to just take random pictures of me like that lol? You could've at least asked first for whoever took that.

### Damage Reduction Questions?

Question regarding the multiplicative damage reduction: How they got the 58% was by multiplying the damage that gets through right? (70% * 60% = 42%) damage gets through therefore the reduction is 58% or 100% - 42% right? Want to be sure the math is right here. So how does the Divine Spirit shield work when used with a Staff of Light? Would the reduction be 70% * 60% * 50% = 21% so 100% - 21% means that you can essentially (assuming they are using melee) reduce your incoming damage by 79%? Then of course your prayer usage would be rediculously small also? Now please tell me if my above calculations are wrong, but lets assume you use a misasmic spell on your target first then switch to the Staff of Light and use the special? We can take the 21% or .21 and multiply it by .5 to get 0.105 or 10.5% meaning you can potentially reduce a target to 10.5% damage output? Again the final .5 or 50% is more on dps and not actual damage. They will hit at the 21% rate but half of the time so the new 10.5% damage output is more in dps and not actual damage reduction. But is anyone else finding how rediculous this is? Again you are assuming a few things: They are using melee, you have enough prayer to sustain this, and of course that you hit them with the miasmic attack.

My final calculation is: 70% (DivineSS) * 60% (Protect Melee) * 50% (StaffofLight) * 50% (Miasmic) = 10.5% damage output.

With pure damage reduction just remove the miasmic: 70% (DivineSS) * 60% (Protect Melee) * 50% (StaffofLight) = 21% damage gets through or 79% damage reduction.

Please look at the final calculations and tell me if something does not stack, or that I did it wrong. I am assuming everything is multiplicative right? Not sure if this belongs here but the article does discuss using protection prayers so I thought this could be a potentially nice addition to the article itself but I would rather not add it yet until I get confirmation that I am doing this all right. ~~ Blackxp

## The Day the maths died?

The damage reduced by this shield is therefore limited to 2 times one's current Prayer points, e.g. a player with 3 Prayer points can have 60 life points reduced from any attack.

3 * 2 = 60? Good try

In this example was the player supposed to have 30 prayer points or is it 20 times your prayer points in damage reduction

Does anyone know if the effect works against nomad?Thespaceer 21:20, June 24, 2010 (UTC)

It does, I believe Haertyew 21:44, June 25, 2010 (UTC)

## Prayer drain

Isn't the formula for prayer drain ${\displaystyle Ceiling((Basedamage*0.3)/20)}$, not ${\displaystyle Ceiling((DamageReceived*0.7)/20)}$ ? 17:31, October 6, 2010 (UTC)

## Prayer Drain Math?

"and the player would lose 8 Prayer points (since [1]."

One may be so bold to say that 350/20 is in fact 17.5 making the true drain 18?  —The preceding unsigned comment was added by 216.249.72.184 (talk) on 19:33, 27 November 2010.

## Experiment at the bottom - Outdated..

Someone added an experiment at the bottom, claming that elysian is cheaper than divine... but the price for prayer potions is less than half of what it used to be! As of this writing, prayer potions (4 dose) are 3,433 GP, and sharks are 529 GP.

## Where is "Ceiling" on a caculator?

If it is not on the current calculator I use (the windows 7 scientific calculator) can somebody link me to a calculator with the Ceiling function?
