The fortean poste reminded me of my old weather-worker class, which was practically one of the "without spells" variants in its original write-up. In fact, it was kind of a lead-in to the Clerics Without Spells post. Time to update it to the format I've been using lately.
Concept: Rain-makers, people who can "whistle up a wind", or who feel a storm coming on, deep in their bones. Inspired by the Earthsea trilogy.
XP/HD: As Cleric.
Weaponry and Armor: Only gets an attack bonus with whatever weapons the character starts with, plus additional weapons the character pays for training in (treat as spell research at one-tenth the cost.) Can use any armor, but typically use leather, since they are often sailors.
Abilities: Predict the next weather change, sense unnatural weather, or sense weather spirits (elementals, or storm fiends) with a simple roll (as a Cleric Turning a 0 HD undead.) Can also attempt to command winds, waves, elementals or weather spirits, using either the HD of the creature (minimum 1 HD) or the spell level of the desired effect as the equivalent undead HD.
You could, of course, throw in scroll-use rules and use Magic-User XP/HD, using the Necromancer, Conjurer, or Mesmerist as a guideline to put together a Storm-Mage class. But the Weather-Worker described above is more like a country hedge-wizard or a shaman, someone with a gift for knowing the weather.
