Bite Me
So I was Today years old when I realized that Arrows of Biting dealt damage over 20 seconds, not a burst of 30% of damage 20 seconds from the moment of impact. Also, per a quick Wiki lookup, they deal 20 damage over 20 seconds, not a percent-of-max-health amount, which for normal difficulties, can be better anyway.
20 damage over 20 seconds! That is amazing for a lingering effect! And to think I was sleeping on the poison dagger in BG1 as well... Do these biting arrows' poisons stack like the dagger's poison does!?
