On the fifth day, after waking up, I did some thinking, analyzing my abilities, and decided I should get a new elementalist type class, or maybe even two. Just to check what they have to offer in search of gaining more useful abilities.
I bought both 'Air elementalist' and 'Earth elementalist'. They had the standard skillset of this type of class. I upgraded it fully unlocking 'Initiate of air' and 'Initiate of earth'.
Except for the usual stuff bot classes each got one special skill. 'Suffocate' for earth magic, and 'Fertilize' for earth.
'Suffocate' was allowing me to keep any creatures from breathing, by not allowing the components of air in their lungs to get separated, which prevented the red cells in the blood to carry the oxygen to the other cells in their body.
It wasn't really that useful, since I had plenty of more destructive stuff in my arsenal.
