In BtW for multi-classing it is recommended that you choose certain aspects of each class. For example if you want a warrior mage they would either get knacks or the weapon specialization and then access to cantrips and rituals or spells (but not both).
However what if, say with the aforementioned example- the warrior mage gets access to ONE ritual... That is the only one that they can cast. They would still need to be the appropriate level to cast it, etc.
The example I have in my head is a savage druid type character- would have knacks and spells (more combat focused), but maybe eventually they would be able to cast Skin of the Treant, Awaken the Wood or Shapeshift or something (but that would be it).
Thanks for this, the timing is great for my Steel Lords of Carcosa game. Simple rules, cool mechs, one of the best supps I've sen so far. +Large Yeti I don't think there is any scaling involved. It's all just armour class, hit points, shields, and damage. Infantry with anti armour weapons can go up against these, but lots of them will die.
