I'm doing the headband and sash quests. Just completed them. As an Iksar to avoid a hardcore faction activity, create two lvl 1 human monks: one in Queynos for the headbands the other in Freeport for the sash. ALL of the components you harvest to get the sashes and headbands are transferrable: just give them to your lvl 1 human monks, they can do the turnins, then give your Iksar monk back the sash and headband.
Sometimes you can also find the sashes/headbands in the player Bazzarr since they are also tradeable.
You need 2 human monks, not 1, because the guys for the sash are on different faction than that guys for the headband.
