"Ugh!"
With all the strength I can find in me, I slit the blade of the key down my palm. When the blood begins to stream, I stretch my arm out and hold my fist upon the centre of the sigil, allowing the blood to fall upon it.
As if the sigil can hear me, I name my quest, "Gate of Hell, portal to Infernus, bring me to the Demon of Lust, bring me to Asmodeus!"
There, like how the first sip of blood triggers a thirsty beast, my blood stimulates the sigil. While the light glows brighter, water begins to flow in one direction.
Along with a deep inhale, I spread my feet and step into the middle of the sigil. As it detects my presence, the water rises until it is tall enough to engulf me. I close my eyes and hold my breath, hoping my spell works as the portal drowns me.
