What can Bestow Curse do?

[Sejs]

Yikes! You think these are all possible with bestow curse? I'd hate what you'd allow with a greater bestow curse!

Heh, granted some of those fit better with greater bestow curse (particularly False Visions and the nastier version of Vulnerability), but otherwise, yeah, absolutely.

-6 to a stat (or) -4 to pretty much all checks (or) 50% chance of losing an action, versus Bad Luck, Decay, or Plague Carrier?

You betcha.

Besides, thematic curses are way more cool than just a random numerical you-suck-now.
