I just got a good idea! (good to me at least) So, you know the final fantasy summons? How they're super hard to get but really awesome? Well, that's my idea, summons in N Terraria! I know what you're going to say," But Incredible that would so much coding and so complicated," I know, i know, I'm new to coding and I already know that it takes a long time to make a simple game or mod. It is very frustruating, I know. But still, hear me out on this. Summons would summon a creature for a little bit so that creature could do an attack, but they would cost a lot of mana. They would drop from specific monsters, such as a zombie summon dropping from a zombie. They would also be invincible and monsters would not target them. I was thinking that the best summons would drop from bosses, and they would get stronger based on your summon stat, it seems fitting. The drops would be very rare due to how awesome and cool they are. At this point i'll make a list showing what the summons should do.
Zombie:
Damage 5-10
Walks forward and hurts any enemies who touch him.
Skeleton:
Damage 10-15
Walks forward and jumps on enemies.
King Slime:
Damage 5-35
Very random on damage and acts like a slime towards enemies
Eye of Cthulhu:
Damage 20-25
Charges at an enemy twice.
Queen bee:
Damage 15-20
Charges through all enemies on the same y-axis
Skeletron:
Damage 30- 35
Charges from the left and slaps his opponents towards the left, then dissapears.
Eater of worlds:
Damage 25-30
Charges out of the ground an loops around enemies (basically his loop attack)
Brain of Cthulhu:
Damage 20-25
Appears above an enemy and summons his peepers to him
Wall of flesh:
*only useable in hell*
Damage 35-40
Moves right and hurts any enemy that touches him, appears at mouse pointer.
That's it for the pre-hardmode bosses and enemies, I really don't feel like typing up a big gigantic list of all the bosses and enemies. I understand if Nakano doesn't want to add this in, or wants to simplify the summons. Feel free to come up with more summon ideas!
