Is "Chance to defeat MR" the whole story?

[Veras]

So I just spent many turns in front of a hydra zapping a wand of paralysis with a supposed 36% success rate, but never landed it once. According to the log, I started with 8 charges, which leaves a (1-.36)^8 or 2.8% chance of this happening. With this in mind, I was wondering if "Chance to defeat MR" was entirely accurate for determining zap success. Every single message was 'easily resists', and it was a nine-header, if either of those play a role. 0.18-a0-912-g81d1dc4.

Yes that was just bad luck.

Alright works for me, just wanted to make sure I wasn't missing some other obvious factor (to the tune of sleep-awareness or something)

That's a 1/35 chance, it's gonna happen. You've miscasted 1% spells before, too.
