Per the description, MSIII has a 60% chance of summoning one creature and 40% for two. When cast at level 9 the percentage is actually 99% for one, 1% for two.
// mon sum iii has wrong probabilities at level 1

    Verified, this has been integrated internally and should be present in the next build.

    Confirmed fixed.
    Just a note, you can do this with 2 effects per level:
    0-100 - one creature
    61-100 - one more creature
    Not a big deal, just nitpicking. Actually, it is less prone to the probability interval bug.

    Did you mean:
    0-60 - one creature
    61-100 - one more creature
    Confirmed... erm... well, looked at anyway...
    I've noticed (maybe what Avenger_teambg did) that in each Spell Ability there are two identical 61-100 effects. No idea why this would be... out of my purview capacity...

    Nah, @Avenger_teambg's pointing out that the original files do with three effects what you could accomplish with two. If you have two summons, one that always occurs and then a second that occurs at 61-100 (on a percentile dice) you can replace the way it's currently done--one summon for 0-60, one summon for 61-100, and another summon for 61-100. Same result, more bloat.

    Rather than restructuring the spell, I just kept the original, slightly less efficient way.

    I don't know how to look at the spell code but:

    Using a level 9 Conjurer I casted the spell 30 time and got 2 monsters in 8 castings. Its not exactly 40% (lady luck is sometimes a bitch) but its certainly a lot more than 1%.

    Confirmed Fixed.


    I think you can move this one too.
