I know there has been much discussion about how many relics per model. The last advice I had was that it is one per model, because the rule states you can replace one weapon with one relic.

However, in the Crimson Slaughter supplement, there is a build with 3 relics on a model.

So, that would tell me that we are limited to one of each per army, but that one model can take more than one relic.

Here is the build of Kranon the Relentless

“Chaos Lord with Blade of the Relentless, the Slaughterer’s Horns, Daemonheart, plasma pistol and sigil of corruption”

Excerpt From: Games Workshop. “Crimson Slaughter A Codex: Chaos Space Marines Supplement (Interactive Edition).” Games Workshop, 2014. iBooks. https://itun.es/us/s260X.l

Blade of the Relentless, the Slaughterer's Horns, and Daemonheart are all Crimson Slaughter relics.
