thank you for your great work , i really appreciate it . some of the attributes that wasn't working works fine at the moment like (boostpercentdamage,boostpercentphysical) but im trying to add healing percentage to an item like <attribute key="boostpercenthealing" value="75" /> but it doesn't work at all , so if you can look again at it that would be great.

Why it doesn't work:

blockhit is not executed for COMBAT_HEALING cause you cant block healing this is why it doesnt work

How to fix:

execute blockhit for healing or add additional handler for healing boost
