Slogra and Gaibon

You fight these 2 in the Alchemy Laboratory. They can be a tough group. Kill Slogra the spear skeleton first by whacking him out of Gaibon's hands (an axe sub-weapon or the summon spirit spells are excellent here) and look for the pattern in Gaibon's attack. He will shoot small fireballs, sometimes in a line, all of which you can block with a shield. When Gaibon gets to a point where he turns red and gets really excited, it means he's nearly dead. Try to take him out quickly. The Basilard has short range, but the attack speed makes it well worth using.
