The change appears to have been to make summoned weapons get credit from more talents. They have worked work with every appropriate talent I tried on my wizard chars. The talents recognize if the weapon is ranged or melee. (so a melee talent won't work on a summoned wizard wand for instance). They receive an accuracy bonus regardless if they correspond to specific weapon types listed in the talents (e.g. the accuracy talents). I haven't tried stacking multipel bonuses though.
They are still the base weapon type. Hence a wand is still a wand, but it also a "universal" weapon if it was summoned. So it can get credit from wand talents (e.g. dangerous implements, blast, etc), and talents flagged to apply to universal types.
If u want to try something particular, just save game, go to an inn, reroll, and attack inn patrons and see if the bonus applies.
I appreciate the response.
Is there a list somewhere? I wouldn't even know where to start. (not to mention it'd take a while) I mean, of course a wand talent should work with a summoned wand, a two-handed talent with a summoned staff, but I've no idea what sorts of talents the devs decided, "Yup, this talent and this talent should apply to *all* summoned weapons, no matter the type".
I mean, I'm attempting to build a melee wizard using the parasitic staff and I'd like to know what talents that aren't obviously connected to this type were so important the devs created a new category for.
