I Have The High Ground - General Kenobi... now might be a good time to have the high ground

Obi Wan's ability is 'A Certain Point of View'. This allows him to interpret the high ground according to his own view of the situation: for example in the picture although he is below Darth Maul he can use 'A Certain Point of View' to actually be on the high ground in comparison to him. He uses this ability at multiple points in the series, including when Darth Vader strikes him down and he ascends to a higher plane of existence (Vader had thought to counter him by fighting on a flat, featureless floor but this backfired) granting him unimaginable power through 'A Certain Point of View'.
