I almost never use black dart. It's a huge waste of will in most cases. Transfix, compell, and sap will are typically far more useful
Indeed. The Channelled version is even more risky. You expend a Might, then a good few Will points in order to succesfully cast it on that 5+ (so as not to waste the Might), then need a 3+ to Wound (4+ against a few targets) and then need another 3+ on the D3 roll, or the Might is still wasted as you'll cause just a single wound anyway. Assuming the target doesn't have a Will/Reistant to Magic, which makes it even less likely to succeed.
If you can reach the target in melee, much better to transfix, charge some guys in and cause a wound (or more) that way.
