Certainly, Mind Techniques and Spirit Arts have some differences.
Because Divine Soul Telekinesis attacks are fast, most Divine Thought Masters are accustomed to directly initiating Divine Soul Attacks or attacking with materialized Divine Thought Power.
For Divine Thought Masters, speed is their greatest advantage.
However, if they employ Mind Techniques, the attack speed becomes slower, giving opponents a chance to prepare.
Therefore, under most circumstances, Divine Thought Masters do not use Mind Techniques.
Moreover, Mind Techniques are quite rare.
As a result, very few Divine Thought Masters employ Mind Techniques.
Additionally, most Divine Thought Masters are not combat oriented; they mostly use their Divine Thought Power to assist in concocting Elixirs, forging Spiritual Weapons, etc.
Thus, they are generally called support-type Divine Thought Masters.
However, those who are truly skilled in combat are different.
