Well I don’t recommend summoning characters because to me it has been over used and kinda seems like a excuse to get someone’s waifu, someone extremely strong, or a mix of both. If you do the character summoning thing I recommend everytime he summons one there must be a test or quest to gain their loyalty that must be as difficult as thier tier or the summons could have a time limit thats based on how much mana MC has and when their out and about it puts a dedicated piece of his mana into lockdown so he can’t use that piece of his mana reserve for anything else except his summon and the summon while in existence would gradually eat up that mana and if the summon wants to do anything that requires mana it drains that mana dedicated to them at a much faster rate a example would be if a goblin mage wanted to cast fireball it would shorten its time by how much mana said fireball cost.
interesting idea also like the ranking of bloodlines I rarely see any good lol fanfics so really looking forward to to this my only suggestion is Dues-san think of an ending or end game per se like how you want to end the fanfic or what do you want your MC to achieve by the end of the book. This helps in avoiding the infamous writer's block. Good luck in your writing journey and have a beautiful day 😁👍
