A Square shield is a type of metal shield with a rectangular shape.
Compared to the kiteshield, both have very strong Slash defence. However square shields are strong against Stab attacks and weak to Crush attacks while kiteshields are vice-versa. This is similar to the relation between platebodies and chainbodies; however, kiteshields will have the same or superior Stab defence to their square counterparts. While they provide less overall defence than a kiteshield, they weigh slightly less, take fewer bars to make and do not provide negative Magic defence.
* Black sq shields can only be obtained as monster drops. White sq shields have the same bonuses except for an additional +1 Prayer, and require completion of the Wanted! quest, after which they can be bought from Sir Vyvin.
