New Animal Companion: Giant Falcon

I struggled for a lot of time to give my eldest boy the nature-electric-tank type of character he wanted. I changed my perspective a lot of times as he grew up and changed his own- but a lot of good stuff came out of it.
This is one of the latest bit. This new beast is adapted from the Tome of Horrors' giant falcon statistics.
