Resist Check and Charm Question
 

Did some searching but couldn't find the answer so apologies if this is redundant. When you charm a mob does the game designate the duration of the charm at the time the spell lands or does it continue to check to see if it will break every tick? I know at times when I've had a mob charmed for awhile Tash will wear off. I'm wondering if that makes it more likely to break or if it just checks my charisma and the mobs MR at the time the spell lands and then assigns a duration then. Thanks in advance!

Your charisma and the monster's magic resist is checked every tic that charm is active.

Charm duration itself has a few factors such as your charisma,the mob's MR and your level vs the mobs level.

A broken tash shouldn't readjust the original charm timer, the check should only apply at the point where it lands. But do reapply tash again when charm breaks, obviously :p

While we are talking charm, how important is 200 cha for a bard to charm effectively?

My friend brought up to my attention that high charisma on a bard is important for the initial resist check.

For charm, it's not important.

Charm will only last 3-4 tics max so any difference between 200+ and ... say ... 110 is negligible. Charisma helps with missed notes and lulls. As such you should always pseudo-favor this stat. I've got about 145 charisma in normal gear iirc and leveled all the way to 60 mostly charming while lfg. Charm breaks so rarely before the charm expires that I generally went HOURS between early charm breaks.

I only break out the charisma gear when I need to lull break a high level camp (BM in velks, crypt or king area in seb, SG etc).

Dexterity helps with missed notes, not charisma.

Ok so cha is needed but not to the point where its a major focus. Got it ty all

I thought CHA also helped with mez resists.

Enchanter
200 CHA + 59+ shaman = 255 cha
205 CHA + self buff = 255 cha
>255 CHA buffed is your goal!<

Make sure the mob is tashed and preferably malo'd. Give it -magic resist items.

Yes if your tash ends on the charmed target it's MR goes up and it gains chance to break on server tick.

Your CHA + Targets MR + Your Lvl vs Targets lvl are all known to factor into enchanter pet breaks.
It's not a duration or a timer. It's a check every server tick. You can literally have your pet break back to back, over and over if you have bad luck.
