Most animals associated with magic directly often also represent wisdom. Although if you are talking actually storing energy, you might also look at say animals who may go hibernating or a metamorphosis (the latter could be a bear or caterpillar/butterfly)jack1974 wrote: I'm not sure what to use for the Mana/Energy potions though.
