She recently awakened her dire panther animal companion, making it the equivalent of a 9th level fighter with better first-round attacks (Pounce, Rake) and has been wild shaping into everything from a lizard (to scout ahead) to a rhinocerous (to knock down doors).
For a few sessions, I had mis-read the rules and was allowing her to wild shape into dire critters, which was sick and wrong. She'll get that ability back at 12th level.
She rides into battle on the back of her awakened dire panther, uses Mounted Combat to keep the panther (the party's best fighter) from getting hit, and freaking lays a swath of death with a shilleleagh and bramble / spike (from the Defenders of the Faith book) enhanced quarterstaff.
She also has a nifty 4th level buff spell that is giving the entire party +4 Str and +9d4 hp (avg. 22) for 9 rds that stacks with their Endurance bonuses.
Also, she killed a dragon with a poison spell. Yeesh.
Her pass without trace has made it impossible for her enemies to follow the PCs back to their hidden lair, allowing them to make raids without suffering any reprisals. That right there is crucial because in D&D the side that is prepared for a fight (short-duration buff spells active) generally wins.
Those are a few things, but you get the idea. It's a really powerful and versitile class, IMO.
