How to mod quench life?

Kay, so I got quench life and I was slightly disappointed due to the fact it sucked in every possible way.
I was wondering if there would be a way to turn it into a 'save or die' attack.

 

Maybe late but i found a (for the moment) working version to make Quench Life that way by replacing the spell in SpellList.mes:

// 59 -- Quench Life
{3950}{AoE: Tgt_None, [Begin]AoE: Tgt_Obj_T_Critter | Tgt_Obj_No_Self | Tgt_Obj_No_ST_Critter_Dead | Tgt_Obj_No_ST_Critter_Undead | Tgt_Obj_No_ST_Critter_Mechanical, [Callback]AoE: Tgt_Object}
{3951}{Cost: 50, Resist: (stat_constitution @ 0), Info: aggressive}
{3954}{AI_Offensive: 17}
{3955}{[Begin], Type: EyeCandy, 2, Add, Play: Callback}
{3956}{[Begin], Type: ObjFlag, obj_f_critter_flags, OCF_PARALYZED, FLAG_ON}
{3957}{[Callback], Type: ObjFlag, obj_f_critter_flags, OCF_PARALYZED, FLAG_OFF}
{3958}{[Callback], Type: Damage, Dmg: 1}

Do not ask why this work. First i had "{3958}{[Callback], Type: Damage, Dmg_Flags: Full | Death}" but when you playing on hard, you get the bug with only dealing 75% damage of the remaining Health so you can't kill with the spell.
