Eternal Essence – Faster AI turn + smarter AI.

Hello! I downloaded the "Patch for fast turn speed on XXXL+ maps with high PC intelligence," which has a closed thread on this forum; here is the link: /topic/7746/. When selecting a map, there are additional settings, but they are in English. I translated them into Russian, but it's still unclear what they mean, specifically Lookahead Depth, Neutral Champions, AI rush discount, Artefact Guards, Taxes, Eight Skills. Could someone explain these settings in detail?
And another question: Is there a mod that prevents the computer from splitting its troops? Because split troops are easier to kill.
