Oooh what's that cutie? Meet QQQQQ the nightowl.
Nova is kinda working but not exactly. Her shadow guards are not spawned and there's an UNKNOWN PACKET reported by the server each time you use Q. This packet does exist even in Acharnes client (id 0xBF3), but never implemented on server. Probably had some extremely niche use before, but pretty common now with the nova skills. So it's a build-from-scratch situation. I'll have to force myself to play some nova on retail first, to get a feel of how the shadow guards should work.
Not really feeling like it just now, instead spent the whole week fixing pets/servants/maids/npcworkers to maybe investigate how ai-controlled entities are handled in general.
