1) Why are you hitting a Zinogre with a Thunder-element weapon in the first place?

2) Probably because the Thunderbugs that make up the entirety of a Stygian Zinogre's elemental abilities are so used to eating Dragonfell Berries (or whatever they eat to give them the Dragon element), they actually become vulnerable to the Thunder element. Maybe the Thunderbugs have lost their natural ability to generate the Thunder element because of their unusual diet, and because they aren't letting off Thunder-element attacks, the Stygian Zinogre can't develop an immunity.

Basically what I'm saying is that the ordinary Zinogre could possibly develop an immunity to Thunder-element attacks because its Thunderbug partners are constantly generating electricity. Because Dragon-element Thunderbugs DON'T generate this electricity, the Stygian Zinogre doesn't have an immunity.

I hope that makes sense.
