Make Wall of Brambles disappear when the thorn hunter dies

[Velikolepni]

As the title says. It is very anoying to have to press 5 several times to make the individual squares of brambles disappear. They should all vanish at the same time, preferably when the thorn hunter that summoned them dies.

Frankly I'm surprised they didn't already count as summons.

Or at the very least set the message "the bramble patch crumbles away" to be muted by default.
