Jaheira cannot weild Usuno's Blade (ninjato) +4

Anaximander

Druids are proficient in Scimatar/Ninjato/Wakazashi? She can equip Belm for instance but Usuno's Blade +4 she cannot equip. It is red bordered signifying not equipable. The text description of the weapon lists fighter/druid multiclass as not able to equip this.

Is this some hair splitting technicality and intended, or a bug + a typo in the description? I do not recall bringing Jaheira to Watcher's Keep in the original bg2 so I cannot comment on the original content status.

Additional Note: I did look at a walkthrough that described most of the ninjato/wakazashi oriental style blades as not being usable by druids however it is said the Yamamoto +4 is in fact usable by Jaheira. I have not tested this myself but it is a bit confusing what is intended here.

Druids can only use scimitars, not wakazashi or ninja-to. The item description has explicitly labeled it not usable.

This is intended behavior, from weird rules in pnp. Druids are only supposed to use "nature based" weapons, and scimitars were the closest thing to a sickle (wtf) in the guide or something. It's stupid but that's not a bug or a typo

What a shame oh well deeper into the keep is a nice scimitar but oh so hard to get.
