There is an
Activated developer console for DKS, based on the demo (there was no feedback if anyone tried it with the full game).
People have reported using
Cheat Engine to freeze their hit points; there are 'cheat tables' for D2:ED and DKS. There are specific trainers for certain game versions, as well.
The Developer's Cut version of the game has an official Developer Mode cheat window. You may have or be able to upgrade to that version (see
here). DKS saves work fine in D2:DC, but D2:ED saves are not compatible.
