There was a possibility that the Power Rank Up couldn't be used to break through from False Divine rank to Initial Divine rank.
After all, it was given out as a reward when they were only at Late Celestial rank. There was a possibility that the limit of it lay in their current power rank at that time, and not their power rank after using the Baptism rewards.
Due to this, Jade's use was to test it out for Zayne. If it worked, then he could naturally just copy what Jade did.
If not, then he could decide which order of rewards he would receive, using Jade's reward order as a reference.
After Jade used her Power Rank Up reward, she designated it towards her 90% Time Sovereignty.
After all, to become a legitimate Initial Divine rank powerhouse, a 90.001% Supremacy was required.
Of course, there might be other power systems that didn't use Universal Law fragments as the core of the power system. In such power systems, it might not require one to have a Supremacy to reach Divine rank.
