Scarlet witch crown - spawns redstone around you in the mine, if mined will have random effects such as, speed 7 for 10 seconds, small explosions added to your pickaxe, drops emeralds for 10 seconds when mining, something like that with chaos in mind
Ultron pick - when mining an iron block it multiplies turning other blocks into iron blocks and iron ore, has a small chance to drop vibranium on iron blocks being mined.
Quicksilver feet - crouch to gain speed 20 for 5 seconds but also blindess 1 for 5 seconds. This is to balance out the speed so you arent exactly sure where you are going.
Darkseid feet or legs - holding crouch breaks a 3x3 down in the mine and is like a drill. This could be a shit idea but im trying to think of other ways to mine.
Darkseid eyes - shoots a beam in a random shape (like darkseids beams ) similar to superman eyes however it enchants ores turning them into emerald and obsidian
Storm head - crouch to make it rain around you, if people touch the rain they are dealt half a heart of true damage a second and have slowness 1
Storm chestplate - crouch to spawn lightning around you like the zeus kit from kitpvp
Storm legs - when using a rod has a chance to pull up 500x fish, like an abundant harvest
Storm boots - spawns ice below your feet like the previous map item, also have no fall damage
Shoblette rebalance - pick has same ability but explosions are bigger by 20%, no fall damage when holding pick, has a higher fortune enchant and works on all blocks ,coal to emerald.
Flash pick rebalance- maybe make the gold spawning more aggresive
