What are the absorb abilities?

Question

Are there any abilities that can actually absorb damage like water/volt absorb, and dryskin or those the only ones. Also is the healing affected by moves normally being not effective or does it heal for the regular amount of damage

Answer 1

Storm Drain (Water), Flash Fire (Fire), Motor Drive/Lightning Rod (Electric), and Sap Sipper (Grass) are some other abilities that can absorb attacks but none will restore HP like the ones you mentioned.

And it restores HP as if the attack was neutral.

I didn't add in the ones you mentioned.
