Talk:Control Ward/@comment-24206354-20170326212620/@comment-30641829-20180706093516

A control ward becomes visible to all players whenever it disables anything that is stealthed. So, for example, if the control ward is disabling a stealth ward (regardless of this stealth ward's position), the control ward becomes visible to the enemy team regardless whether or not you should normally be capable of seeing it.

And therefore, since it is visible, you can attack it outside the brush. However, of course, if the control ward is not disabling anything, then the brush will conceal it.
