Decrepify tooltips suggest that foreign Nether Wards cannot be targeted Decrepify
can indeed target every Nether Ward
despite the notification "Ability can't target Wards that aren't yours". Foreign wards can be created by an allied Morphling
or an enemy Rubick
. Furthermore Rubick cannot target own wards such as Power Cogs
with stolen Decrepify
. So the notification should be updated to "Ability can't this ward".
