The only way to kill ye self is too use nades.

actually i have tryied but i had 1 health
I killed myself with fire nades till 100 health left
then started desolation By the time its fully charged i got 1 hp
I use it loose no hp lol

I used it and i died. but with a few usage of nades

Yea the lowest you will go is 1 hp now if someone is attacking you then yes you shall die!

Since desolation takes so long, and u have one health left, i dont think it will work
but maybe if u are poisoned or on fire. But I still dont think it will kill you!

Once again its IMPOSSIBLE for you to kill yourself with desolation. The lowest you will go is 1hp now if someone is attacking you then yes you will die.

Unless, of course, they die first.

No but i have killed myself with grenades

If you die immediately after using Desolation, it was not because of Desolation, but because of the enemy attacking you doing damage during and/or after casting Desolation.

Desolation CAN put you into a more precarious situation, causing you to die. Useless spell.

I don't think it is useless though. It gets you out of precarious situations pretty easily. If you max it, it can save your life. It is very useful when boarding flag ships as well. You can kill everyone on the flagship in one hit (unless you board a Colossus or any ship that high of a level).:)
