Enchanter Rune I-V (entire line of spells)
 

In Emu, currently, the Rune line of spells absorbs only physical damage.

On Live, Rune absorbed physical damage as well as spell direct damage components (both direct damage spells and the initial burst of damage from any DOT).

It did not (and does not) absorb the damage from DOTs such as poison, disease, or Heat Blood (for example).

This is true. That's why the Wizard epic was so good. You could rune yourself and then Manastone/Manarobe off of the rune, then re-apply once you actually started taking damage.
