Dynamic upgrade is also a merging method that requires two chargeable cores of the same level with the following characteristics:

1. Chargeable core upgrades below level 12 only have a 50% success rate.

2. Chargeable cores below level 12 can be randomly upgraded by 1 to 4 levels if successfully upgraded.

3. For chargeable cores above level 13, choosing dynamic upgrade is equivalent to merging upgrade. It can only be upgraded by 1 level, with a 100% success rate.
