Even a Japanese hand has a grip of 8 cm minimum, you add 2 cm below and there is only 10 cm protruding from the hand with a 20 cm wand
Personally I would have taken a 30cm wand.
for 10 cm more, that's juste 1/3 more space, it's worth it with the * 5
and he doesn't have to hold it at the end, it's like the staff, he can hold it in the middle
when we see the forms of the staff and the explanation, it is normal to think that what matters is the total length, or the length of the circuit (because it is logical that no one is going to hold a staff like a wand, it's way too heavy), so it would be enough to have a staff twisted or circuit twisted on a staff/wand to reduce the length of the staff/wand by increasing the total length.
Or staff with flexible joints and attachments to the body
@Wolfwood824
Yes, but it's much lighter and more flexible, because it's fabric (even if you can see something that looks like metal, or leather on the forearms, hands)
and the defense applies wherever there is material, while the leather will not be everywhere on an armor
there is no leather armor, with protection under the arms for example, while the fabric will protect this area and for less weight and it will not hinder movement
(the flexibility of the material and the fact that the defense is of magic origin will make that an attack will be enveloped by the fabric, the contact zone will be greater, therefore the damage will be applied on this greater surface.
in this case even a sharp weapon will have a blunt effect, because the defense will apply over the entire contact surface, even if the edge cuts the tissue the sharp weapon will always be in contact with the defensive effect
in the end if we follow this logic a little rigidity (to spread the shock zone over the body) and padding underneath would be a good idea, rigid layer where it does not interfere with movement, gambeson on top with the same "magic" fabric but in a flexible gambeson, with only 5 layers for example)
@humbleoverlord
that is what I thought in the other chapter,
they did not yet have the technology (the dwarf said "tramping wrought iron does nothing" and steel has just been invented) and above all they have better materials available than steel, so that limits the desire for research
