Q: Dear Sage,
Can a druid have more than one animal companion, as long as the total HD of his companions is equal or less than the amount allowed calculated by his level (with bonus HD)?
A: No. A druid is only allowed one animal companion.
(In previous versions of the rules, druids were allowed multiple animal companions, but in practice this generally leads to one player taking way too much time at the table.)
About the Author
The Sage is a mammal classified in the bear family, Ursidae, native to central and southern China. Debate continues as to whether he is truly a bear or more related to the raccoon rather than the bear, or perhaps in a family of his own. When not eating bamboo and answering rules questions, he works under the nom de plume of Andy Collins as an RPG developer in Wizards of the Coast R&D, where his development credits include Complete Mage, Dragon Magic, and the Player's Handbook v.3.5. He can be easily recognized by his large, distinctive black patches around the eyes, ears and on his rotund body.
