mahoy ^~^ Transcendence serves to raise the base stats of a hunter (attack, hp and defense), which means it makes them considerably stronger. To do this, you need to have a copy of them, and said copy must be at least a 3★ (for example, if you want to transcend a natural 2★, you must bring its copy to 3★). When your hunters are at 3★, you can transcend them once, using 1 copy, and he becomes a t1. When your hunters are at 4★, you can transcend them twice, which means that after using one copy to t1 you will now need 2 copies for t2. Finally, when your hunter is at 5★, you unlock the final transcendence, which requires 3 copies for t3. So in the end, you need 7 copies of a hunter to bring it to its full potential.
