“A few abilities and damage type mechanics have been reworked. There are now three primary damage types and a Spell Immunity Piercing status with each. Each ability now carries a notation in the tooltip indicating these.
The three damage types are Physical, Magical and Pure.
Physical is affected by Physical Armor, Magical is affected by Magical Damage Resistance and Pure is affected by neither.
Magic Immunity has now been renamed to Spell Immunity. Spell Immunity only defines if Spells interact with it, not how damage itself is handled. This means that on its own Spell Immunity status does not reduce any damage.
Black King Bar, Repel, Rage and all other previous forms of “”Magic Immunity”” now grant Spell Immunity status and a 100% Magic Resistance bonus.
In the vast majority of cases, the interactions are still the same, however an example of a case that would be different is if an ability has both Spell Immunity exception and has Pure damage type. Previously the damage would not have any impact, however now it does.
Ability Tooltips now have these fields:
-Damage Type: Physical/Magical/Pure
-Pierces Spell Immunity: Yes/No
If the Damage Type is not Magical it will be colored differently to make it easier to notice. The same is true in cases where Pierces Spell Immunity is Yes.
There have been a few abilities rebalanced with these mechanics in mind. In some cases the intent is to maintain similar balance, in other cases as an adjustment to their balance.

Additional Notes:
1) Composite Damage: This damage type has been removed. There are no longer any abilities which use Composite Damage.
2) HP Removal: This is no longer considered a Damage Type, and its remaining uses are as an alternative cost to Mana for spells to use (Sunray, Burning Spears) or as functional HP modifications (Armlet, Sunder, etc). These are now considered usage costs in the game and are never lethal.”
