...the player desperately needs every experience point available.
On my 1st playthrough, I was 2 lvls above the enemies in the late game, which was detrimental to the gameplay, because it made the game even easier. Phantom Forest and final bosses were incredibly too easy. So just destroy the Guardian with the wand if you find the fight boring.
I almost didn't finish the game because the Guardian fight bored me (I wasn't aware about the wand). I saved in the middle of the fight and stayed 1 month away from the game.
