Summary: The range of the entangling roots of the summon spriggan minion is too short imo.
Problem: The spriggan minion has a tendency to stand a bit behind me and the range of the roots is most of the time the gap between the spriggan and me. At least half of the roots it casts have no effect besides taking up an action it could have used on thorn volley.
Solution: Please increase the range of the roots expend for just the spriggan minion, maybe lower the width to compensate OR change the AI of the spriggan to move closer to enemies before casting the roots.
