The Spirit Realm

I have read posts suggesting an AA called Greater Rabid Bear works good with spiritual channeling. But in my AA windows I only see Rabid Bear. I bought 1 rank in Rabid Bear but noticed no increase in my HP regeneration. Is greater rabid bear still active or has it been combined into later ranks of rabid bear? I want that 350 hp regeneration but would hate spending a ton of AA in more ranks of Rabid Bear only to find out it provides no regeneration.

The higher ranks of Rabid bear have the chunky regen effect

Good to know Thanks
