I have tried the Aevitas and Armara riutals on our server.
None of them is doing their actual boost effect. All they do is spawn a large amount of mobs.

They have the correct visual effect tho (according to videos I have seen on Youtube)

We are running EOD Synthesis 1.3-RELEASE, which is a 1.12.2 Minecraft with 1.8.4 Astral Sorcery.

Correction.. The reclection bonus on Armara seemed to work. On MY arrows.

Any changes/edits/updates to the pack?

The modpack is unchanged at the moment according to the server admins.

I'm having issues replicating the mob spawn stuff. Are you sure you've got aevitas and not pelotrio linked?

Armara deflecting ALL projectiles in intended. It used to do it to grappling wands, too.

Screenshots or videos, perhaps? not able to replicate on my side.

This was reworked for the next version so those things now 'work' instead of being reliant on the intensity of starlight incoming. specifically refering to the lucerna ritual here. :P
