As a Taoist you will be looking for a well balanced kit DC (Destructive Class) and AC (Armour Class), SC (Soul Class) and MAC (Magic Armour Class).
SC bolsters your own spells, from poisons, healing and damage abilities, as well as some of your summon’s own damage.
Although you are not a close combat class, you will still require AC to prevent being caught out by groups of creatures, but will also require MAC to be able to prevent long
range magic damage.
Keep an eye out for items with Holy, as although it does not effect all spells, it has a lot higher impact on certain spells then SC does.
