I've seen tasers built as NND and EB Stun only. What do you think would be an appropriate def for the NND aspect?
Possible defenses to a NND approach could include being insulated or grounded (like a Faraday suite).
As an alternative to NND I recommend reading the Stunning option for Change Environment introduced in APG1.
The following notes are from such a build that includes an initial -6 to the CON roll.
