Gambler's Blade

Choose a magical bonus of +1 to +3. This sword
gains that bonus to its attack and damage rolls.
For each point of bonus you choose for the
sword, you take a corresponding penalty (-1 to
-3) to your death saving throws. You can change
this magical bonus each day at dawn.
This weapon is cursed and becoming attuned to
it extends the curse to you. Until the curse is
broken with a remove curse spell or similar
magic, you are unwilling to part with the
weapon.
