[Spell] Arcane Circle Myrshalee [Secs] 0.5 [Mana] 24 [Skill] 0 [Effect] 
When cast with other spellweavers, creates an arcane focus which enhances the effects of spellweaving spells. The general benefit of having the arcane focus is increased intensity and increased duration of other spellweaving spells. This spell only works when at least one other spellweaver is standing next to you; in effect they cast the spell with you. Each spellweaver in the circle provides a bonus of one point (up to a maximum of 5 total), plus one point bonus if you are standing in the center of a physical arcane circle, abbatoir, or pentagram, and one more bonus point if you are in the Prism of Light or Sanctuary. One person casts the spell and every other spellweaver within 20 skill points of the caster will receive the arcane focus. Arcanists who are hidden, or are already in another arcane circle will not be a part of your circle. The arcane focus has a limited duration, but is also lost when any of the spellweavers is over 40 steps away from any of the other spellweavers in the circle.
