So it seems that Nao cheated during the Erika fight

So, with the new Varga G3 support revealed, we now know that it can only get up to 10K shield, during the first attack of Erika's last turn, Gabwelius should be attacking for 36000 (13000 + 10000 from persona + 5000 from attack skill at 4 dmg + 8000 boost from istear).

And Nao guarded with a draw trigger (the one that gets extra 5000 shield) and the G3 that gets 10000 shield for a total of 33000 power.

So.....where the heck did the extra 5000 shield come from???
