not positive if this is a bug or not , can someone explain this

[apoxhd ig]

check ur damage again when proccing for example ur arcane armor (the damage buff is not stacking) and also try popping a 30% damage elixir(its not stacking) you will see the difference. without procs and elixirs ,30% not stacking gives more than 25% stacking

also you have the privilige of me being your friend, you can always ask me for advice
