One of my favourite things about IWD is the ability to construct your whole party the way you want it without missing out on NPC quests and banters etc and how this allows for idiosyncratic tactics and potentially silly character concepts that can work within a specific party.
My current IWD:HoW party is :
Tori.
Human Fighter Dualclasses to Druid
uses spears and scimitars
Shivrynne,
Gnome fighter
Uses greatswords and halberds
The Scholar
Elf Fighter/Mage
Uses axes and casts armour a lot
Angelo
Elf Fighter/Thief
bows and crossbows
Ari of Pythi (named after Aristarchus and Pythagoras)
Half-elf Cleric/Mage
I'm interested to hear other people's party ideas.
