Do the various animates stack or are they concurrent?
Animate Carrion 1 allows small animals to be re-animated and can control 1HD/caster level
Animate Carrion 2 allows medium animals to be re-anminated and can control 2HD/caster level
Animated Carrion 3 allows large animals to be re-animated and can control 3HD/caster level
So, does a 9th level necromancer able to control 18 squirrels, 6-ish boars/black bears, and 3-ish cave bears?
Or Just 3 HD total per level of all creatures? Which could be like 54 squirrels, or 8-ish black bears, or 3-ish cave bears.
just need to think this through a touch.
