Thank you so much for sharing your combos! Gonna try them over the next few days! I totally gotta go thru enemy types and rethink them. You're correct, some are way easier in certain builds, for me the Scorch/Flame go down way easier than Phalanxes, gonna see how that works with ranged.
Re. exceptional/unique, I couldn't get them to work as-such but sometimes they did drop a levelled (lvl 3) shock axe which is a winning item but like, its just a part of my regular melee build. I did try the buzzsaw? melee item and it worked but again, was part of the melee build and relied heavily on regular melee items. So it was more of "any melee item will work here" rather than " this specific item"
Cannons/Grenades -> I just couldn't find the g.launcher & grenades consequently enough. Cannons (as seen from cannon spider/launcher spider) just don't seem to work right now yeah. :(
I really wanted a working shotgun or SMG build, but I just can't seem to get it.
Pistols/SMGs - I had a levelled (lvl2? or 3?) MechaFinger but that didn't seem to work for me, gonna try again while paying attention to which enemies I pick.
