King Groot in Cav EQ
King Groot is on one of the power drain paths in this month's cav EQ 2.2. The only problem is that he' s immune to power drain. I know that you can just bring in a typical counter for him, but what Avenger champ are you supposed to use against him here to use the nodes as intended? Am I missing something or is the answer just bring a good mystic and ignore the monthly nodes?
