Lets go one step further!
Geomancy doesn't JUST do poison damage, it also does earth.
Anyhow one possible way to do it is one of them could just increase the damage or terrain you create or transform OR increase your DoT abilities.
Or heck make Fire give additional damage outright (like say... 5% per level) but only after 2 turns.
