Spring, Clockwork Steed

Spring behaves as a combat-trained pony, with
subtype construct. He has basic combat tricks
and abilities, but he cannot make attacks. Spring
cannot learn new tricks or abilities.
A gem on his pommel is enchanted with an
illusion spell, so anyone who sees him considers
him a normal pony, or appropriate steed for the
area, will save to disbelieve, doesn't work on
those who know his true form.
