We love mods, and as such, most of the things we create are designed to be modified themselves. Below are links to guides and tutorials for adding to or editing systems in some of the projects we've released.
Adding New Resonant Crystals - Resonant Crystals can be modded into Bards College Expansion to offer alternate effects to those found in it natively, or to add support by Shouts from mods.
Creating New Outposts - Additional Outposts can be added to East Empire Expansion to add support for deliveries and location claiming to new areas, such as new regions or islands added by mods.
Supporting Mod Legendaries - Work-in-Progress, this tutorial will get a major overhaul after a future update to McClarence.
