And over time managed to put what little finishing touches he needed to before the Kon/GF event. And didn't Isshin say his powers were awaken somewhat but not very much after his wife/Ichigo's mom died.

No dirct mention that his powers slightly returned after M died but that his restis was losing the hold over Ichgio and then he said that when Hichgo awaken fully the ties were cut. If the panel is anything to go by the awaking happen when Ichgo fought Bayaka. How many days was it between that fight and the Kon/GF event. Pently for manga world.

Maybe to sell it in SS in a shop to people has protection from hollows or has a project or test for his captaincy.

And who is to say it uses his power to make the field? Could be Kon's/anyone that is in danger. he gave the charm to ichigo before he left to save Rukia
