You now possess the ability to summon numerous invisible hand-like appendages from your body. These appendages can be telekinetically moved in any direction you want, bending, and twisting, and turning up to a range of 1 kilometer.
Only you, the user, can see and sense these hands, which act as extensions of yourself, with precise innate control and dexterity over each one as if they were your original arms. You also have unlimited multitasking capabilities.
A single hand is strong enough to effortlessly tear apart limbs, bend and break bones, reduce rocks to dust, lift heavy duty trucks and launch them dozens of meters in the air, etc. To further enhance their strength, you can combine multiple hands to create larger and more powerful variants. Each combined hand doubles their overall strength, enabling you to reach a level where lifting entire islands and crushing them to dust becomes a distinct possibility. Due to their weightless nature, each hand can achieve extreme hypersonic speeds without sacrificing any of its maneuverability in the process.
The unseen hands are completely impervious to almost all forms of harmful attacks, and are able to block and negate them all, from physical attacks, to energy attacks, to magical attacks, and even attacks of esoteric nature, etc. Their only weakness is susceptibility to damage from psychic attacks, if they do manage to land. If a hand is damaged, you can retract it into your body for a maximum of 24 hours, depending on the incurred damage, to allow for complete healing.
You have the capability to summon up to a thousand hands simultaneously. With enough practice, at their maximum potential, the Unseen Hands and the force behind each one will be capable of shredding through the strongest metal alloys as if they were a piece of paper.
If you wish, the unseen hands can be retracted completely into your body at any moment, and in case of danger that would cause you bodily harm of which you are not aware, the hands will instantly and automatically react to protect you.
