heres a few bugs, first off you cannot hit enderman with the vajera as well as the ender dragon.
It's no bug my addon. Vajra used constant value of damage. Also doesn't allocate priorities at mobs.
Second is just an opinion. The fact that the vajera 1 hits mobs AND 1 hits blocks is kinda op. I think if a tool is so powerful against EVERY block in the game it should at least only do half a heart of damage to mobs. Like your vajera is more powerful than a nano-saber which is the highest tier sword and only sword, it has no other functions.
If you get that mode code working I'd love to see some new type of nano saber (quantum saber?) that had different modes that would apply the effects of enchantments that are in the game.
That said I love your mod and think everything else is balanced perfectly. Also the sphax textures for the new items are just about done.
one last thing breaking ice with the vajera only sometimes turns into water.
I initially thought to make a vajra only the construction tool, but given the cost of craft recipe and principle of work, I added damage value for mobs. I think it's more balanced for this tool. And i also want to add different work modes for vajra.
