This list is probably trash, but I made a jutsu list and mastery. Some are custom, some are from Naruto. I did this for fun. Hope u enjoy. I can make more. Leave a like or comment if u want another mastery done or even expand fire more.
ADVANCED FIRE MASTERY
Mastery: Rolling Ignite Every fire move now causes a burn (ignite) that stacks. It's duration is refreshed upon a new fire move hit. Playstyle; Use all fire moves quick to try to get a big ignite or play fire slow for longer burning ignites.
Upon picking fire adv maybe old fire jutsus can now be enhanced. Or even update the jutsus we have. Here's the list for that;
Fire wall;
Bigger wall maybe even a second wall is created now.
Fire bullet;
Second bullet is casted behind the first or maybe make a 4th projectile.
Fire explosion;
4 tile teleport build into jutsu, jutsu still casts if no target is in range.
Fire Ball Jutsu;
Anotha one.
Fire Dragon;
Bigger is better. Maybe add a knockdown effect instead cause dragon.

I feel like if nin can start adding 5 jutsus per year, we can reach 25 new jutsus in 5 years. That alone is better than the current 3 jutsus in 4 years we have now, which is still an average of less than 1 jutsu per year.
