[a humble lich]

Mainly make Chronic Depression less crippling. The way it is written many be realistic for severe cases of depression, but I've know several people with depression (myself included) and the description of the disadvantage is harsh (and probably worth more than -15). As it is written, the character can do nothing without a self control roll. Perhaps make it clear that unlike other disadvantages, regularly making self control rolls does not represent bad roll playing but represents the character fighting against their depression.

Also, in the particular case of my character, it was unplayable because it was one of many mental disadvantages gained in play which were added only an already sizable list of mental disadvantages. She had issues, and as a player it was hard keeping them all straight.
