What would it cost to have remove disease cast on them at a local temple in a big city?
Remove Disease is a level 3 spell, minimum caster level 5, with no costly material component.
You'll need to be in a small city or larger settlement.
Spellcasting: Caster level × spell level × 10 gp
5 x 3 x 10gp = 150gp.
You'll need to notify the spellcaster in advance so he can prepare the spell the next day.
That will result in 1d20+5 vs the DC of the disease.
Filth Fever is DC 12, so you/he will need a 7 or higher on the d20.
Necrotic Boils is DC 11, so you/he will need a 6 or higher on the d20.
You may be able to pay to have the spell cast at a higher caster level, as long as the NPC spellcaster is of sufficient level.
To have a better chance at being cured, you could get a CL 11 Remove Disease for 330 gp if there's a level 11 cleric or druid in town. That will automatically cure the disease even on a 1.
