Lets cut down this evocation ritual to it's bare essentials (it's the evocation ritual's bare essentials, making it possessive.)

You dont need tools, you are right.

You need to be able to enter theta-gamma sync, be able to establish a connection with the entity and feel its energy, deepen the trance to the crossroads state while building the structure in your mind, project the structure into the physical and have the entity to solidify before you. The entities energy will condense into the structure and give it form, kind of like ectoplasm. You can do this because in the ritual you are becoming the Operator, and calling upon your own innate god-like powers.

Structuring takes practice for a lot of people.

There are already threads about stripping evocation away from more traditional styles. You more or less did it here.

I think EA does a good job of that as well. There is a lot of discussion about his methods already.

I am sure you have seen Lady Eva’s Simple English guide.

Simple English Demonic Evocation Guide

This guide is intended to be both simple and easy to translate. Read it through at least twice to understand all the stages. If you are using a book, follow the instructions in the book about any prayers or magick words of power, this guide is very basic, and you can add things to it from the book or method you are using. If you are not sure whether magick is safe, or whether you should take the risk, do not perform an evocation, or you might just become more worried and unhappy. You will ne…

In the end, the methodology does not matter. What matters is you get results.

If you dont like the LBRP xD Dont do the LBRP. As its been said, the magician is his own most powerful tool.

The hard part isn’t getting them there, the hard part is appeasing them so they’re fine with coming

I wouldnt necessarily say that. If you are calling them as a God (like you say in your own OP), with your true innate power, they will show up and don’t need appeasing. You are not some sniveling worshiper, bowing down to them. You are not above the spirits either (at this point). You are their equal at the very least, because you are embracing your God-self when you are in that space of evocation. Treat them like one. If that happens to include, oh I have some incense that you like, or I have some wine for you, then so be it. It is nice to make sure guests are comfortable after all, like offering your friend a drink.
