And how is that related to the fact that your tower is being taken away before you've had a chance to build the desired Dimension Door? With the old rebuild, wouldn't you have run for a chair?
The point is that with a normal rebuild, in that time you could have learned Imp, Fly, and Summon Caca, for example, and still maintained the ability to continue the fight. But in current realities, you can spend a ton of resources searching for Dimension Door without getting a single intermediate spell. Which is exactly what the speaker above is saying.
But overall, in light of the ban on KS and the Cloak of Renunciation, such a rebuild looks quite sensible (the finale is as if with magic, but without magic)
True, now КЗ becomes a mega-imba
