It wasn't like Aditya was holding back. All the stats, boosting skills, and functions of his Mythical Classes were activated and had pushed his stats to a new level. His armour was severely damaged, and two of the three abilities of the armour were no longer functional due to the damage.
'Only Life Guard is now usable.' His current health had dropped to around 32%. The Golem had given him more damage than all the other previous stages' foes combined had done to him.
『Function 2 - «Life Drain»
When your health drops by 75%, The Crimson Warlock set will activate «Life Drain». When «Life Drain» is activated, each time damage is received by the opponent with a weapon or unarmed attacks, you will recover a small portion of your health. The amount of health that you will recover is directly proportional to the amount of damage that your attacks do to your opponent.』
