Can someone tell me how to poison drinks food etc? I saw poison detectors and that thrilled me. Can I actually poison someone, that would be awesome.

Moved to a suitable forum.

Letters and notes forum is for IC discussion. In other words, your character talking with another via note or letter. Not OOC questions.

That said, you can poison drinks and food if you acquire poison and use it on the drink or food. There are a lot of different poisons in game with different effects and strengths.

Where can I find poisons? Can someone tell me area.

No.

There is no specific area.

Find an NPC that sells them, find them randomly on quests or ask PCs if they have poisons, just expect to get into trouble if you ask the wrong person.

This is definitely something to find out IC vs. OOC.

Note that poison application to weapons requires the feat or a dexterity check. Poison application to food, drinks, potions, etc. requires no check, but involves placing the food item on the ground and then using the special power of the poison (each of which has unqiue effects) on the item.

Poison suitable for weapons can't be used on food, poisons suitable for food can't be used on weapons.
