Here is the list of mage friendly augments we get from the fancy Bruce Lee pants.
Magic Attack Bonus+4%
Physical Damage Taken-4%
Magic Critical Hit Damage+10%
Magic Burst Damage+10%
Here are some list of possible combinations I came up with.
For the nuking SCH:
Magic Accuracy+4/Magic Attack Bonus+4%
For the healing SCH:
MP+25 Enmity-4/Cure Potency+5%
For the soloing SCH:
Physical Damage Taken-4%/Movement Speed+8%(If no Gaiters)/Haste+3%
For the HNM SCH:
Magic Burst Damage+10%/Magic Attack Bonus+4% or Magic Accuracy+4
There are a nice amount of situations we can use these combinations. I think personally I might go for MP+25 Enmity-4/Cure Potency+5%, or Magic Burst Damage+10%/Magic Attack Bonus+4%. I have Mahatma and think that's a fine nuking piece as is.
