I didn't know is this the right section but will post here . Invisible shadow don't give any buff on summy dunno if its the same whit Concerra,usually in other svrs it gives some psy ressistence ( 5 or 10% depend of server and balace whit classes ) . Other think i notice is that Vital drain on bagy didn't give the usual 75% psy ressistence ,but give AMR( all magic ressistence) ,and Rush manace gives 10% guard rate ( usual gives 10% psy ressistence) . I hopŠµ i have been in help whit this post
