The SRD entry makes it seem interesting, but after making one, I saw no means of activating it. Does it only work on strike? Otherwise?
IIRC a number of that rod's abilities are approximations of what they should be due to engine constraints, but it should be able to cast Shout, Lightning Bolt, or Call Lightning and functions as a magical mace. It's been so long since I added it, but I do recall that a number of items I added with casting abilities only worked if the wielder had the same spell on their own class' spell list. Though they could use the spell even if they were too low in level to do so. Perhaps changing the 'class_cleric/druid/sorcerer' bit to 'domain_special' in the protos for those items would allow the spell to be used by even non-caster classes? It was an early mod, and in this case, not entirely rules compliant.
I was very much looking forward to the Thunder and Lightning ability which combines lightning bolt and shout. I had a Wizard equip it and it worked, just with a disappointing effect.
