(bug) improved dampen magic not working

Problem: "Improved dampen magic" in mage arcane talent tree not giving improved stats to spell when it is cast on player.
It gives correct values on the tooltip in the spellbook but not when you cast it on yourself.
For instance- The tooltip in the spellbook says it gives 50 reduced magic damage and 100 reduced healing. then when you cast it on yourself and it is only 40 reduced magic and 90 reduced healing.
