i no longer take the completion so you wont get a ss from me, unless they change the looting. there's usually someone who takes the completion in group though so maybe they'll post it up.
if you *need* to land a spell, land irresistable dance - no save. i usually dance, enervate scroll, enervate, enervate scroll, fts if its one of the more dangerous mobs. otherwise just dance if theyre not ones im going to firewall.
also, ive found that mass charm and suggest are broken, or something, i dont know. 1st time in chains i was casting mass charm, but they would always break a few seconds later (much sooner than their save timer) so i switched to mass suggestion, but they would still break a few seconds (rather than 4 minutes) later.
you can use ck. they are not immune to stat damage, just resistant. its not efficient though unless you have a mass group and youre cooking/slicing them up.
another good point i forgot to mention.
-know your enemies and comrades strengths and weaknesses
-act on the above in accordance with the above
