is it gonna enhance an old school elder macer...that is will it be worth the time and effort and expense to add 120 mystercism ...plus 120 focus which iam guessing will be easy.......will the char be a lot more fun/harder hitting than box standard mace warrior???
Depends on how you play it and how you equip him. But in general, yes.
Stone Form will help your macer take more damage.
Cleansing Winds will give you another method to heal, cure, and remove status effects.
Healing Stone will give another form of healing.
Nether Cyclone will give you an area attack.
Rising Collosus will give you a strong summon to fight alongside.
Several of the spells are offensive, which can help a dexxer with some finishing moves.
However, it will not increase the damage you are doing with the mace.
It can be a big time mana hog depending on how you use it.
It has no travel abilities.
It may require some fc/fcr jewels (again, depending on how you play it)
Lord God has a very good macer/mystic template in his thread called "Mystic Dexxer solo'd slasher". You might search for that thread and give it a good read. It is designed for being solo and will probably help you decide.
