ToME: the Tales of Maj'Eyal

So, the Shock skill either dazes an opponent or, if that fails, it shocks them which lowers their resistance to stuns and dazes.

Does only the shock skill have the shock effect or do other failed daze attempts also produce that effect? More so, if something is immune to stun/daze, does this make them susceptible?

I'm wondering because of Tempest. The idea that one could lower stun and daze resistance with Chain Lightning is fairly appealing and I was considering trying a full-stun Archmage that used lightning primarily (if Tempest adds said effect to air tree spells) and then earthquake and flameshock to keep enemies dazed and stunned while I whittle them down…

Only Shock has that effect. And to my knowledge, there is only one other way around status immunities, the Wet status. (You can get it from Biting Gale runes or some stuff in the Water tree.)
