Realm Grinder Guide

Realm Grinder is one of the most content-packed idle games out there, and Research is indicative of that. Research unlocks after mercenaries and is accessible from R16 for the Vanilla factions, R23 for Neutral factions,  R29 for Prestige Factions, and R175 for Mercenary. That is dozens of hours into the game.

This mechanic is fairly complex, so you should take notes here.

1. The Basics

Each research facility is related to several factions. The Vanilla factions are related to one, Neutral to two, Prestige to three, and Mercenary to one. To acquire research points...just play the game. There is a  formula for how much you get: 100000 * (1 + 0.01 * x ^ 0.7), where x is RP total of facility affinities. At each reincarnation level, you will get new RP equal to your Reincarnation number to upgrade each facility. 

Each facility has a limited number of Research slots at first, depending on how many upgrades you have for each facility. This changes when you reach R100, where you only get 1 Research slot, but a majority of researches no longer take up a  slot. And this further changes when you hit R160+, where the slots turn into a budget system based on each research point value and starts at 3500.

These research points are permanent, but your upgrades and slots will reset so you can use different builds each run.

2. The requirements

Each slot or budget upgrade has requirements, which work much like trophies. Here is a list of the ones that can be earned easily and early.
