Thaumcraft's endgame primal wand focus is arguably one of the most powerful spells currently available with the limited amount of thaumcraft chapters in infinity atm. And typically it deals in explosion related damage. Which is never a problem because most if not all servers disable explosion damage. But it seems on infinity normal node 5 both the explosion damage and the actual damage from the spell seems to be entirely disabled. It only knocked back entity's now rather then doing damage at all. Tested it on servers outside MyM and it works fine even with explosions turned off server side. Jw if this is fixable. P.S. Node 5 expert and normal isn't listed on the "Choose the server where you need support" option so ill put network on my threads for now.
I tried it on just a straight up hamachi private infinity server that only had pvp turned off and difficulty set to hard. So it didn't even have bukkit and very few server settings changed. Which most likely doesn't help you at all because that means I entirely turned off protections against explosions lol.
