player.attr
 

I can't remember for sure, but aren't some player.attr default, initially, for other things? And also can't you only go up to a certain number with player.attr before it doesn't work or something like that? I thought I saw this info somewhere, but couldn't find it and not for sure obviously. Please excuse the stupid questions or bad wording, I'm sick as crap right now...

There's a length limitation, if you're using more than 100 characters in an attribute you might want to re-think your approach. You should be able to get away with storing strings and numbers without problem though.

Some of the attributes in the 20-30 range are used by global effects, they're not reserved or anything but it's a possibility for trouble.

attr[1] is used in the default ganis for hats.

attr[2] is (or was) the carried object.

attr[3]

Yes, my mistake.
