You need for your roll weavesight skill modifier. It should be in your charsheet in the skill section, most likely lowest in the list. You roll d20 and add the modifier on the roll. You are meant to roll over the DC to learn the weave what you see with weave sight.<br/><br/>For initiaties it should be easy as they get in 1st level a special class feature to get +4 to weavesight checks (easies up learning the weaves).
