Author note:-

Mikoto has not unsealed the rinnegan yet so she can wood style or truth-seeking rods.

Her bloodline is only 13% pure and per year only 1 per cent is released so. She needs to unlock the whole 13 per cent so she will not become like Nagato or have any backlash or loose the power control like Broly. If she gets 13% from the beginning she will be going on a rampage until she dies.

And she has the origin energy so only someone from the top upper realm can stop her. So that's why she getting 1% purity as her chakra convert in origin energy and become compressed, pure and more potent. So she can adjust to the origin energy and control it.
