on summoning miscasts

[absolutego]

i don't play spellcasters often, but i had a nice vampire summoner who got himself killed by a miscast that called forth a hostile balrug. it was the second time, as i got an nice ice fiend earlier on. in either case i was trying to cast level 4-5 spells at excellent. how does this work? do miscasts scale with spell power?

to add insult to injury they were permanent. maybe abjuration would've worked, but i never found it.

Just bad luck, I think.

"Failure to cast spells causes various generally nasty things to occur, becoming nastier with spell level and spell failure. Miscasts come in severity 0,1,2,3; 0 is always harmless."

i read that, but it's not very informative. i guessed severity should be tied to spell success, instead of spell power, but it may be the other way around. casting spells at 95%+ success shouldn't put you in those situations unless the rng truly hates you (and even so!). anyway, what got me riled up was their permanent status. they were pretty much choking two key access points.

this makes magic much riskier that i thought, unless you have divine miscast protection. unfortunately i was cast into the abyss and had to convert from sif to lugonu.

summoning miscasts are notoriously nasty
