17. Shield Twisting
Shield twisting is a technique employed by advanced players often used when soloing one or more NPCs or in combat situations with fluctuating mana levels, such as extended PvP battles. It involves casting Lightning Shield when mana is plentiful. As the shield charges expire, the player alternates or "twists" to Water Shield to enable some mana regeneration. When that shields charges expire, the player again twists back to Lightning Shield. The same thing can be done by a Resto Shaman in PVP with Water Shield and Earth shield to balance the passive healing of Earth Shield with the mana regen of Water Shield.
So the purpose of shield twisting is to strike a balance between higher mana regen and higher damage / damage reduction. In ShamWOW this is controlled by the following two values:
Water Shield Mana % If your current mana percentage is below this value, then ShamWOW will always cast Water Shield to increase the mana generation for the fight. This value must always be less than than the Lightning Shield Mana %
Damage Shield Mana % If your current mana percentage is above this value, then ShamWOW will always cast Lightning Shield to increase the damage done to attackers. This value must always be more than than the Water Shield Mana %
So what happens if the current shield charges expire and the mana percentage is between these two values? This is where the "shield twisting" technique occurs and the alternate shield is cast. As the charges on that shield expire if mana is still between the two limits established it twists back.
Can I force it to always use Water Shield?
Yes. Set Damage Shield Mana % to 101 and set the Water Shield Mana % to 100. Your characters mana can never get above 100 so Water Shield will always be up.
Can I force it to always use the Damage Shield?
Yes. Set the Water Shield Mana % to 0 and the Damage Shield Mana % to 1.
Do I really want to Shield Twist in Cata?
Yes, it is still important while leveling as your mana regen may not be sufficient due to your gear or other factors to minimize drinking frequently or to solo an elite. At higher levels, you typically won't use it except in special circumstances ( PVP, soloing an Elite, etc.) Ultimately you control whether Shield Twisting actually occurs or not by the values you choose.
