I have been thinking about new spell ideas for monstrology and looking at the categories on the wiki page and seeing the number of creatures in each category the giants seemed to be the largest category that has not been made into a monstology spell yet. This would be a good option since the creatures span across multiple worlds. The category would include the fomori from avalon and the Minotaur and cyclops form wizard city. It would also include some creatures from dragonspyre azteca and grizzleheim making it much better than more specific category spells in monstrology.
Another good choice for a monstrology spell would be wizards. That like the previous creature class mentioned has many creatures across multiple worlds including dragonspyre avalon and empyrea and even the catacombs. It would include some unique creatures too like malistaire, morganthe and even the headmaster.
Of course that makes sense but what I as a monstrologist are afraid of is when they do release a new monstrology spell it not include all of creatures to collect such as the parrot or imp spell and with the spells being a hundred thousand gold i want to get what I am paying for.
That is true, yes. Monstrology spells tend to be more costly, but then again 100,000 gold is not extremely rough to come by and there can always be more creatures in the future that can be used with that spell.
