Random abilities and 3.1.2

[Timo Pietilä]

Hello.

I'm playing comp which is vanilla 3.1.2 r1971.

I have found a lot of items which should have random ability (regen, ESP etc.) but have not. Some of them do however.

Has something changed, or doesn't ID reveal them always?

Which items? There was work on bitflags which could possibly have introduced a bug (there was already an earlier bug relating to randarts and slays). It will be hard to track down without specific items. Also, were these drops, found on the level, bought in a store, etc?

I think most of them are dungeon findings. Gondolin weapons (all of them, no matter where I see these) some *slay evil* and I'm using a Lothlorien Bow with only FA which is what they have always. I think I have also seen one or two Blessed without extra ability. The last one I'm not sure. Gondolin is definite (found at least 15-20 of those all without anything extra), and the only Lothlorien I have seen is also pretty obvious. *slay evil* has been a bit less noticeable because there has been so few of them and I usually just check "does this have ESP? No?" -> ditch. One latest just didn't have anything: blessed, like all *slay evil*, slay evil (obviously), WIS bonus, other than that: nothing.

I think only those weapons are affected. Everything else I have seen have had something extra. Aman, permanence and elvenkind have extra resist, defenders and holy avengers sustains, helmets with extra abilities have extra ability. Haven't found magi cloak, but there is another comp player that has and he has ESP from magi cloak

If you are referring to your comp char, the bow you are wielding has increased light radius for its random ability.

You are correct. I didn't notice that when I looked at what it has. Extra lite doesn't show where all the other "extra abilities" are listed. So it is mainly just Gondolin weapons. Or there is something wrong with somewhere deeper (Nearly ready to kill M, and haven't seen single RoResistPoison, which is really weird).

I haven't noticed any problems, and I tend to look for this problem since it happened so many times before. I've put in some debugging code, and haven't seen anything unusual. Take a look at my most recent comp dump to see a gondolin with ESP.

Can the "random ability" hit a already existing ability? If that is the case then what I have seen in Gondolin weapons might just be RNG mocking me. Otherwise I'm definitely seeing a bug here.

Now at work, didn't have time to play yesterday and this day looks to go in similar direction, so might be before I have time to test again.

I think RNG is acting funny in my game anyway. I think I have seen only four RoFA and only one RoSI in entire game, but I have seen at least six or seven Rings of Acid in very short time period. Also not a single Ring of Resist Poison, and I have had access to illumination due finding Palantir for a while. I investigate unknown rings, because at this point unknown rings have high probability to be artifact rings.

The code checks against the flags of the ego. It is now considered a bug for the random ability to match the ego. That used to be possible in 3.0, but hopefully not now.

I usually don't bother to ID gondolins without ESP, or even gondolins with ESP , but I will try to check to see if I see this bug happen in my games.

I just found pretty good Gondolin with ESP. Apparently RNG was playing tricks on me. I'm sure that none of the previous ones did have anything extra, but now the game is behaving just fine.

I put in some serious debugging code, and everything appears correct. Gondolin generation does not even consider a matching ability of SI, FA, or Lite. Random abilities used to be listed at the end of object descriptions, but now all flags are reported in fixed order. You may have missed the slow dig or feather fall early in the description.
