Acid + DMT: Preferable to take DMT after the peak of an acid trip. On the come down. It helps clear up the head. At the end of a long lsd trip you can feel tired or burnt out. A little foggy in the head. The DMT just seems to clear that right up and give another round of visuals. Of course you can do DMT on the peak too but that can get a bit intense..

Acid + MDMA: Classic combination.

Acid + 2CB: Absurdly visual.

DMT + Ketamine: The combination of the ketamine 'hole' and DMT is interesting in that the ketamine becomes more visual and both drugs out of body effects seem to amplify. It also a strange to combine the feeling of becoming a single point and being one with everything.

DMT + MDMA: Again prefer DMT on the come down. Seems to reset some of the negative MDMA comedown feelings although wouldn't advise this as a potential remedy for MDMA comedowns. Rather it is a pleasant way to end a good MDMA experience if your in the right head-space.

MDMA + Ketamine: Disembodied ecstacy.

MDMA + Ketamine + DMT: See DMT + MDMA and Ketamine + MDMA = pretty much sums it up.
