I enjoy blindweed, since it’s basically a free win against a mob of your choice. Evil Eye charging? Blindweed to stop the charge. Scorpio? Blindweed, now you can actually approach them and get free hits on them. Warlock? Blindweed to stop them from shooting at you.

Blind makes them not see you, cripple makes them lose track of you and also facilitates free hits, even in melee.

With warden it’s basically invisibility on demand, which is super nice as well.
