To me, I felt that your spell best represented the "assassination" theme that I imagined. All the others didn't really fit into what I interpreted the theme as. Well the theme is open to much interpretation, but I guess that it's different for each person. I sort of interpreted it as something to do with infiltration, ninjas, etc. So well done.
Well if the theme calls for subtlety and complete stealth, relevant to the theme wouldnt not having a plethora of sfx be + points?
Since the thread was closed, I'll answer your question here.
This is exactly why there's a "Quantity of Effects" field
It's also required because a spell with way too many effects could lag the game =o
"Her dreams were shattered to faint dust of realization, and her will and smile withered away to blackness with the same grace as her smile of red roses. The coldness of her silver eyes still reflected thousand dreams through seven devil smiles, just like a broken mirror reflected raging lightning bolt with greater intesity than it normaly would. However, there was one thing still waving in front of her eyes, the last sign of humanity in her. With the scythe raising towards the skies, the colors of the hope flew away to darkness, the last remnant of the butterflies of will she felt. Free of morale chains that were holding her true face down, with a slow grin on her face that told that Hell was raining on earth, she unmasked her betrayal of life and swang down."
Rose became death. Mirror became anger. Butterfly became lost hope. And mask became truth. Complete role reversals implement the dramatic feeling in the story, and if executed properly, can create a stunning dark atmosphere.
'Unmask' has a dramatic and to some point, expected appearance, while 'Unveil' tends to be more elegant and feminine, so I give my vote to Unmask. It even, when said, has that dramatic shout in it, while unveil flows like silk fabric. Hope that helps.
