While Clyde tells the player sacred acorns raise their defense, the actual mechanics of the game show otherwise.
When an enemy attacks the player, if the player has any sacred acorns in their inventory, that number is used to calculate the possible maximum value of a randomized number. If the number selected by the randomizer is 1, the enemy's attack is successful; otherwise, the player effectively dodges their attack and no damage is dealt.
However, due to the way the calculation is handled, the odds that the player will actually dodge an attack are very low/impossible unless they have all four acorns:
Int(Rnd * (AcornCount / 2)) + 1
