If you're instructed to roll multiple dice (with one exception, see below) and more than one shows the highest natural result, the Perfect Illumination ability will trigger that many times
Even just at your second turn, you could be looking at five or more mana , more than enough to cast a few spells, a higher-cost commander, or some powerful mid-game bomb at the earliest point of the game
If he fails and for example hits you two times, you can Yamato9 or Katakuri8 to heal you and let your opponent try again
The controller of that delayed triggered ability is the player who controlled that other ability as it resolved
Token engines have a similar use: Cards like Ophiomancer, Sedgemoor Witch, and Bitterblossom produce consistent streams of sacrifice fodder to pour into your outlets
