Right. That's why I wasn't talking about prayer points, I was talking about this tax.

And that will depend on how many and what you produce. You can tell me what you want to produce and I'll tell you the cost, but I am not about to make a table for the costs of every possible combination.

Basically as far as efficiency goes, it will be most efficient (Cost the least) to get everything you need in one large group, but that will mean you won't receive any of the items until they all are done. Getting the items one at a time will apply the tax to each individual item instead of the whole group, and ultimately make it cost more.

Look at Dervish and Drakel's crap for example, it costs 11PP to get it all in a group upon completion or 14PP to get the items one at a time once they had enough PP to summon them.
