We had some unexpected downtime last week but that has been fixed (thanks Pecunia), we're back now, sorry for any inconvenience this may have caused.

As you probably know, Return of Rome allows the usage of Triggers in custom scenarios. But where/how do you start? This guide explains everything very well and provides descriptions of what every condition and effect does:

SpoOky's Guide To Triggers and More! (DE Version)

As ROR uses the exact same Triggers as AoE2DE, this guide can be applied. It may be a bit overwhelming at first, especially if you have never used Triggers before. I suggest taking it step by step and just start fooling around with some of the more simple ones, and eventually you'll get the basics down. There are countless ways you can achieve the desired results, wether that be changing the stats of a unit or a diplomacy change, pretty much anything you can think of can be done. Be creative here and of course don't forget to do multiple tests to make sure everything works as it should!
