[Brew] [11.0_Beta] Elixir of Determination

1. Notify whether it is recommended to use Purifying Brew by comparing the purification value generated by the last time using Purifying Brew with the real-time purification value. 2. Calculate the estimated shield value for the next Elixir of Determination based on your purification efficiency and the previous purification value 3. An interesting thing: the max shield is up to your max health:] Currently when you select the 'mantra of purity'(Purify 10% additonal stagger), the purification efficiency is 70% instead of 60%, it seems an issue. I still use the 60% to caculate the estimated shield when the 'mantra of purity' is available. However, this will result in the shield value of 'Elixir of Determination' being slightly higher than the estimated shield value. I will fix the purification efficiency when it matches the description of 'mantra of purity'.
