Bind an acid ball on an elemental wand for efficient armor removal. You don't really need 4 dissolves, 2-3 should be fine, the main problem is the armor and acid ball is a much better solution to that rather than dissolve.
This will not take care of Belts and Wands and other non-armor items so be careful with you decision. A Watergate Wizard with Jellies would be quite effective as it was pointed out.
The only belt that absolutely needs dissolved would be the Colossal Belt (whatever the tough -2 one is). You can cancel the regen with poisoned blood, ghoul rot, deathlock, etc, and the veteran belt does absolutely nothing if you get rid of the armor. Yes the wands are a problem, but i doubt many books run more than 2.
I think 3 dissolves is perfectly fine. It's not like the "stack armor, regen, vet belt" strategy is necro specific. This is pretty much the stereotypical battleforge strat. I've played against it and the only thing that is really worrisome is the armor, and the only spell that really makes gains against armor is acid ball. That's just my experience though.
