I use the circus and then Abdul's in every game. Using Abdul's and trading golden pyramids is not unlike multi-looting ib that I keep saving and reloading until I get the item I want. Don't usually multiloot monsters for artifacts though, but I would if I wanted to as it is allowed by the game itself.

I also very often mephisto guilds ro get the last few spells I need before going into Part2 when I play TCC. Don't generally bother with that in the original game though.
