She's one of the most knowledgable Jedi in all of history and has the entire Jedi Archive -- the largest source of knowledge in the galaxy, that also includes portions of Sith lore -- essentially memorized in her head.
Whats so great about Yaddle? As far as I know her best feat is a heroic sacrifice. Thanaton pwned Nox while they were empowered by 2 ghosts, 1 of which was 1 of the greatest sorcerers in the empires history.
Well she's...
One of the most knowledgable Jedi in all of history, and possibly the knowledgable since the time of Odan Urr(knowledge is power and whatnot), has a "rivalling affinity" with the Force as Yoda -- implying similar raw power -- her presence was like something Anakin or Obi-Wan never felt before, her mere presence in the Force amplified Anakin and Kenobi, she held back a massive stream of water that was about to burst through a large tunnel by keeping two doors shut, with no evident strain.
A reason as to why this is impressive: Shaak Ti, one of the most powerful Jedi in history and among the 15 greatest of the era, Anakin Skywalker, who at the time could manipulate CIS dreadnaughts, and Obi-Wan Kenobi, who even as a padawan was noted as one of the greatest Jedi of all time, have had trouble holding back a significantly smaller stream of water.
Dueling-wise, she one-shotted an Akk Dog that could've killed Adi Gallia, noting that three Akk Dogs gave Mace and Depa some grief, fought off hordes of warriors while just a padawan and stomped a dozen combat droids in what, from Kenobi's perspective, was "no time at all" indicating she was possibly moving faster than his perception.
