Where can I download Duke Patrick's SCA Shield Tricks? I saw the .esp listed in the BOSS masterlist, but I didn't find it on Nexus or Planet.

Might be one of the older DP mods - he had tons that have been deprecated by his other newer mods.

Alos, note that his mods are hosted on TesAlliance these days, not nexus.

Yes, what anithinks mentioned. DP pulled many of his older mods, although I'm not entirely sure if all the older mods are replaced by new ones.

At least, I haven't found any new SCA Melee Combat.

Nexus has more of his mods than Alliance. But I couldn't find it. Maybe it's merged into SCA Combat. It doesn't say in the readme though. I found that one on Planet.
