[3.5] What do you think of Mystic Theurge?

[Thrice Dead Cat]

Let's look at this:

Raw power at level 20.

Wizard 3 / Archivist 1 / Mystic Theurge 10 / Wizard + 6

Now, you can be either:
Wizard 20

or

Wizard 19 / Archivist 11

The latter is better.

without EE:

Wizard 17 / Archivist 13

That is better than most wizard 20 builds, just due to the added versatility combos.

This is true, but Wizard 2/Master Specialist X/Incantatrix Y/Whatever else floats your boat Z is still better than effective Wizard 17/Archivist 13. Although, to be fair, effective Wizard 17/Archivist 13 is pretty awesome, as you can basically afford to leave slots open for niche spells once you hit about ECL 10, earlier with Wizard 3/Archivist 1 entry.
