Randomly remembered the spam monster idea, wondered which forum that was at and did a search.
[2009-11-22 23:53:32] <Somagu> I think a better idea would be a small chance for a "scroll of wishing" to be a unique scroll that summons a 4x4 tile spam unique

[2009-11-22 23:53:42] <Somagu> which shoots out bolts of lightning and spams your text bar
[2009-11-22 23:53:48] <Somagu> and when you kill it it drops a bunch of cans of spam
[2009-11-22 23:53:49] <Chao-Chao> dude
[2009-11-22 23:53:53] <Chao-Chao> spamming your text bar
[2009-11-22 23:53:55] <Chao-Chao> that's brilliant
[2009-11-22 23:54:17] <Chao-Chao> how will you rape spam though
[2009-11-22 23:54:34] <Somagu> good question
For context, search this forum.
Also, a more serious idea, based on the fact lanterns make surprisingly good shields.
A primal relic, very rare. Made of mythril, but since it only holds energy it's very light despite how big it is. Makes an excellent light source and shield. However, if it happens to break it will go supernova.
So this is very rare. Valpurium flaming sword rare. Every turn, it takes damage from within, which contributes to its eventual breaking. Don't go turning it into balsa or anything though, or it'll go off in your hands. When it breaks, first there'll be a crackle of energy (lightning explosion), followed by the cage itself bursting apart (striking explosion), then the supernova, a series of explosions from smallest to largest.

sewing order into the chaos
you spit in the face of random numbers, of chaos
