The Hidden Forest

Hellos,

I got this cool item today, Scaled Shoulderpads of Darkness.

Note the worn effect. Upon striking the dummy in the hidden forest with my group of 6, my chat was spammed with a message saying "Your arms bulge with power as you strike out at your opponent again!" (i think 8 or 9 at once). My entire group desyncs the moment I try to attack. I don't even see any hits going through the desync/disconnect is so fast.

I'm a warrior, and a gnome, if that information is relevant

A great reason to use filters in addition to those built into EQ can use those from macroquest. Here's a quick guide from EZ Server:

Filtering
Allows you to filter what shows in your chat box. You can add an asterisk before the text to act as a wild card, otherwise it will only filter lines which begin with what you type. Wild cards will be filtered if they pop up anywhere in a certain line.
Example: "/filter name add *begins to glow" - Filters out all messages about glowing items from focus effects. The * is only needed before the filter, and is assumed after it
Example: "/filter name add You strike through" - Filters out all messages about striking through your opponents defenses. It doesn't need a wild card because it is the start of the text.
Some popular wild card filters for EZ: *begins to glow (charm focus effect), *has died (NPC death), *beams a smile (lifetap emote), *is struck by a cyclone (every warrior epic), *glows blue (more charm spam), *has been slain by (NPC death), *contorts with rage (Warrior Anger proc), *your wounds close (Druid Skin proc)
Some popular standard filters for EZ: You have slain (NPC death), You strike through (in-game filter doesn't work for this), You resist the (Resist messages), Your faction standing with (faction messages)

Hm filters are fine... but if I play just my warrior and still just disconnect upon trying to attack anything, I feel like there is something wack.

Fixed in next reboot and was also a standing desync/lag issue with attacks that is now fixed.
