Ideas of questionable quality

The chaplain fights vampires, wraiths and wizards so the janitor should fight the blob.

...go on

I was actually writing up a post for this separate to this thread but I was struggling to make it come together.

The simplest starting point would be for the janitor to be highly resistant to blob abilities, in the same way the chaplain is basically immune to vampires. They don't get impeded by regular blob tiles (possibly just slowed movement?).

The problem I ran into is expanding this further without items. The chaplain has a gun, melee weapon (bible) and holy water and is fighting individual NPCs. You could add something extra to the mop or spray bottle but I don't think it would be better than what chemistry could do at the moment.

It doesn't have to be better than chemistry, it just has to give janitors something extra to do. Keep in mind that there are multiple janitors. I say, give janitors "custodial training" which makes their mops super effective at punching tiles, makes them take less damage from getting blob punched, and makes their mop deflect all projectiles from blob turrets. Janitors also could move through all blob tiles no problem that aren't a LoS-blocking wall.
