I have just finished upgrading my elite void to the superior variant.

 

Which bosses does this trump t90 at? Also, is it a viable option for any solo's?

 

Thanks

They are superior at bosses where you do not regularly take damage. Vorago, KK, Nex to name a few

The defence on superior void still isnt that great. But defence doesnt matter for typeless damage. Thats why it is good at rots and kk, also as wkw said vorago and nex when in dps role. I would recommend a decent amount of experience in these bosses first.

 

For solo bosses, any low lvl Boss when pet hunting: kbd, kq, Mole, dks, ... If you are experienced also useable at qbd. Dont use it at raxxor and gwd bosses.

Unlike damage, accuracy has a cap to its usefulness.

if dps is taken as accuracy x damage

then the accuracy sup elite void is taken as 

(original accuracyx1.03)x(ranged damagex1.07), which is a 10% boost in dps at max.

I would say that sup elite void is a set of lv90 armour, with a lot less armour and degrade costs.

You are quite right in that I think it would be rather useless to farm something like Waterfiends or lower level creatures in Void for XP. However for high level bosses with a lot of defense, my take is that every little bit counts, especially with people so much into the metagame as it is.

Tormented Demons. Increases KPH by a noticeable amount. Though I don't know how relevant this is considering Tormented Demons are only what, 5m-6m gp/hr now?

Good point. Void is pretty good for hybridding
