Oh.
I thought the ice would actually get electrified, which is what I thought you were describing.
Still, a quick skim through the first part is actually way more excessive than anything I had ever seen from my Hydrosophist/Aeroteurge party setup in D:OS2. Getting stunned in D:OS2 required one of two other conditions first:
1) Being under the effect of the 'Shocked' status, and then getting hit by an attack that inflicted the Wet status or another Shocked status effect, which upgraded the Shocked status into Stunned
2) Being under the effect of the 'Wet' status, and then getting hit by an attack/walking into a field effect that inflicted the Shocked status, which took you straight into being Stunned
If you walked into an electrified water field without any magic armor, you'd either get Shocked, or Stunned if you were already Shocked or Wet. However, this act also causes all electricity in the water to disappear, as it is assumed that the affected character absorbs it all, so it required a bit more effort to stun multiple enemies at once.
