Level 1: Guardian of the Citadel (Cost 400) - Pippin swears fealty to the Steward of Gondor and becomes a Guardian of the Citadel. He immediately reaches level 5 if below that and gains an additional +1000 hit points and +30% armor.
Pippin can only receive one upgrade from his own palantir (ability):
Pippin is the servant of the Steward of Gondor and one of the four Hobbits of the Fellowship of the Ring. He is one of the cheapest hero units in the game, and he is armed with a number of useful abilities. Pippin may not be the best in direct combat, but his auxiliary powers are useful for scouting and espionage.
For one thing, Pippin can switch between two weapons—his sword, and his rocks. Pippin can throw rocks with dead-on accuracy and they actually do pretty good damage from a distance. He can also use another ability to turn invisible by standing still, and scout the area by temporarily increasing his line of sight and detecting stealthed units. There is an upgrade that instantly buffs him to level 5 for a cost.
Pippin's most powerful ability at level 10 allows him to charge forth in a single strike, dealing devastating damage to an enemy hero or unit and knocking away everyone else that gets in front of him. Besides all of this however, Pippin isn't much of a fighter—think of him as a scout for the early game who can harass enemies and draw their attention away.
"I had the loveliest dream last night."
"It's so quiet!"
"There was this large barrel, full of pipe-weed. And we smoked all of it. And then you were sick."
"I don't want to be in a battle. But waiting on the edge of one I can't escape is even worse. "
"But we have the White Wizard. That's got to count for something."
