Okay, maybe not chains, but I thought it might be fun to have whips in game that would have melee reach of spears and such. It'd be fun to have a cipher with a pistol style weapon and whip like Indy in these puzzled ruins and things we adventure through. A lot of darker orientated characters might enjoy dishing out painful lashes to their foes before killing them. It'd be a cool weapon and unique. I dunno a fun idea but no neccessity.
After watching 20 vids on youtube, really feeling sorry for your version of the wizard class. I was thinking you could give the undead summons of the chanter to the wizard. Everyone says the chanters and ciphers are ruling as casters. A wizard's strength was always his or her worldly knowledge in the mystics of magic (diversity). I think that is why DnD had all sorts of varying schools for them. Everyone has likely adventured and fought the arch villain evil necromancer of various lore before. I know that PoE has it's own lore, maybe there aren't any evil necromancers, but you know the wizzy needs some help At low level, summon spells might be handy to provide that encounter to encounter sustainability and who knows with genies and djinns or devils and angels you could summon whatever in high lvls to further diversfy the class by interacting with the summons.
~Things I liked!: I like the game look, like the monk don't piss me off or I'll dish a world of pain idea, druid hybrid shapeshifting idea, ranger and pet symbiosis idea, song creation of chanters, liked the storybook style arcs that certain places are made special, and like that you're doing your own thing and not feeling the licensing constraints nor creative boundaries of staying DnD. There's a lot to love just watching others play it, but for now I'll play the EE Icewind Dale that's out. Good luck in game making and am sure you have 10000s of requests.
