Setting required level to 2 or higher (doesn't need to be 6) will make the game consider the ability an "ultimate" and will have it go through spell immunity/etc.Req level means nothing at all.
yet it has nothing to do with the points OP stated, just to be able to target spell immune (target, no affect)Setting required level to 2 or higher (doesn't need to be 6) will make the game consider the ability an "ultimate" and will have it go through spell immunity/etc.
Not sure it will allow fan of knives to hit ethereal though. Spell immune, yes.
Depending on what you're trying to achieve, you could simply use another AoE ability instead of Fan of Knives. For instance, Thunder Clap.
terrain deforms cannot leak as its completely local object and its being handled properly as they dont use ref count (at least for my knowledge)Thunder clap is not a option, terrain deformation generating leaks, and not is 100% safe if use a function that calculates terrain Z (desync issue)
I think that blizzard is the best option for aoe dummy spell but this require more test.

not to say Z terrain barely useful anywhere and normally shouldnt be used for sync-based actions

You could put dummy targets on the actual targets when Fan of Knives is being cast, taking the blow for the damage event, then proceed as necessary. Or maybe it's enough to remove/reapply ethereal just in time.
