On such a low player setting, the rolling of items often doesnt do anything else to our rune drops. The table makes it known that 8.18% of the time we lose 2 runes due to too many items rolling, and 24.08% of the time we lose 1 rune. A quick table shows these 3 cases in bold (the first, second, and fourth rows): From here, we can handpick which of the 12 actually mean that we got screwed out of rune drops because the item TC picked too many items to drop. Every drop will land in one of these 12 categories. This third table shows us the entire distribution of how many item/rune picks were successful (if you sum the entire table, they are equal to the full 100% of course). Runes that drop (or try to drop and are later blocked by lack of slots):įrom these two tables, we can cross-reference all the data to make one table that includes all 12 possible permutations of failed/successful NoDrop rolls for both the item picks and the rune picks: Rune Drops not held back by too many items spawning (NoDrop rolls 2-5 times, 0-3 items drop) Rune Drops limited to 2 (NoDrop rolls exactly once for items, 4 items drop) Slots remaining: Rune drops limited to 1 (NoDrop rolls zero times and 5 items drop) We will make two tables one to determine what % of the time there are 1, 2, or 3 slots left open for runes (failed NoDrop rolls for item TC), and one to determine what % of the time we successfully try to drop a rune from each rune slot (failed NoDrop rolls for the rune TC) Using a NoDrop chance of 19/68 in /p1 for her item TC, we can determine how often her 5 item-slots will fill up, and eliminate the chance for 2-3 runes to drop instead of just 1. Since only 5 items can drop, ther is always at least one pick left for a rune to drop, assuming that the rune TC's dont all roll NoDrop.

This means that on higher /players settings or in a fuller game in multiplayer, keys/items have a higher chance to drop, and runes have a much lower chance.

This would lead you to believe that The Countess can drop up to 8 items, but there is a hard limit of 6 items - and unfortunately the items have priority over the runes.

This is also why up to Lo Rune is possible from countess, but is very rare - it would be a Lo dropping just like any other monster/SU drops runes. Note that she can technically drop runes as normal items outside of her Rune TC, so 4 runes is possible. First, she selects up to 5 items to drop, then she selects up to 3 runes from her special Rune TC. As you may know, Countess is special when it comes to drops.
