Load is acting buggy, at least in TF, whenever you remove or wear armor. It will give me the messaging about my shield hindering the load but it doesn't actually load anything. The only piece it's not affecting for me is the icesteel bar-mail hauberk.

> get sip

You get a lumium sipar painted with a moonsilver-edged crimson fireball from inside your backpack.
> wear sip

You slide your left arm through the straps on your lumium sipar and flex, gaining a feel for the sipar's weight.

> load
Your lumium sipar makes the task more difficult.

That's it.
