According to the website of Ranger Raiders, I know Arcane is a skill in World of Warcraft. In this version of tbc, there is a 3% hit between fire and ice, and you need to get a 13% hit from the equipment, which means a 164 hit.

Arcane talent provides 10% hit, which can save Arcane 126 hit level, so Arcane equipment only needs 76 hit level.
