Seize the Flesh

Seize the Flesh is not functioning.
The thorns?? spawn after a warcry but do not explode.
thanks.

The condition for them to explode is using an exerted attack, do you fulfill that? There are bug reports about some Graft skills that don't properly trigger, but I haven't seen any for this one. If it simply didn't work, players would have reported it, that's why I'm asking.
