They do need some range to teleport to a Danca, but i haven't figured out how long..
Also, about the aoe hitting double, i don't think it's because of the Danca being in range. It will only hit double (or even more) if there is another target at the Cyclick's current position, such as a bomb, or a glyph, or the dungeon boss's blue dial cells. I personally think this is a bug. imagine what it will do if it stands on a stack of 3 ap glyphs made by a feca... But of course you can gain advantage of this annoying bug by doing rebirth on them and do the same thing with the aoe.
Also beware of the cyclick's push spell. It may reduce your resists by 100%, or 200% on a crit. 2 cyclicks doing crit push attack on one character, and that character will have the resists like a lvl 50 char :3
