User blog:DT.hak/MOD idea: black scratch spell

hey guys. im back. this time i thought of a spell, instead of an item. this spell is crafted at a crystal ball. to craft it you need:

1 cursed flames

1 crystal storm

1 ruby

1 sapphire

1 emerald

1 topaz

1 dimond

10 mana crystals

10 life crystals

35 soul of night

15 crystals

1 magic mirror

and when you craft it, for a whopping 50 mana you can make an explosion 5 blocks wide in all directions around your mouse, whereever it is on the screen. let me know what you think of the idea.
