After a while of uneventful searching for uses of the toads in Haven and Hearth I began thinking up ideas for them. One of my better ideas was a form of poisonous bait for wild animals such as pigs (who usually eat anything). Say you mixed dead toads with a grain (wheat) and left it out in the open in say a tray (so it doesn't disappear) and hope something wanders by and eats your poisonous concoction. Going back to your trap a while later and finding a dead pig, that is if it hasn't been stolen, would be quite exciting.
Now some obvious cons here is that it may be overpowered, since pigs are quite a difficult creature to kill, thus providing new characters with better items. That said this could potentially be a positive.
Either way, feel free to discuss, add ideas and point out why this would not be a good feature. So I will leave it with you all!
