The grim is complete garbage or pure nonsense, whichever of the two you prefer to call it.
A bit of drain, a bit of debuff and overall nothing useful. Also it's too expensive for what it does. 2 SP cost would be fine even with that odd effect which is underwhelming in usefulness.
Of course that means even engage spell would need a change. Few people use it, maybe if it costed 1 SP it would be more worth having it randomly packed in even without the use invisible druid.
The cost of the druid + engage combo might be too cheap in that case, might. Which is why i suggest first of all a rework on top of everything else.
