Things it took you way to long to learn about BG 1 & 2

Title. The game is over 2 decades old, but I'm still discovering stuff overtime in my paythrough's, and I'm sure others here are to. A few things I've learned more recently:

• TOB >!Sarevok!< has a 3% chance of dealing an extra 200 damage a hit! And a 10% chance of stunning enemies if they fail their saving throw. Somehow I never noticed this despite including him in my party many times.

• The Drow city has several merchants near the entrance, but it's easy to miss because their names are all "Drow" and they aren't labeled on the map.

• In the Solamnic Knights quest in the Sphere it's possible to get the credit (and XP) for both options of sending them home and giving them a home in Amn! Simply pay to send them home first, but right after the dialog where they thank you (and after you've already gotten the XP for it) kill the mage before she can send them home. Then offer to let them join the Order of the Radiant Heart. It's an easy way to gain an extra 45,000 XP.
