neanesis Be careful about testing it in 1.0, it currently doesn't actually work. The Halo Effect node is broken until they patch it unfortunately. It's just... not triggering the spark novas, which really kills the single target AND clear of the build.
The reason I don't really think it's necessary to go for Careful Drawings is that you just don't need it. When you get into the rhythm of The Teleport -> Invocation -> Glyph, you'll find that your glyph rarely goes off before you're ready to do your next teleport.
The build HAS been nerfed a bit in 1.0 (aside from the bug): Charged Reflections and Arcane Mirror aren't nearly as strong as before, but it also is buffed because the GonGonGon invocation actually applies the Brand of Deception for the entire duration, which adds a lot of ward generation.
I intend to do an update to the build for 1.0 once the Halo Effect bug is fixed.
