Here's a brief of what this mod adds:
-Zinc ore and ingot, used for varios stuff, such as making bronze or steel.
-Bronze, a cheap metal that can feed an army! This is as good as iron, but not as long lasting.
-Steel, which is made out of one zinc ingot, three raw iron and one coal.
-Bluesteel, a mysterious metal, made of steel and the bluecrystal, the last being created only in the secret forges of Toulon, can thus be found only in loot tables. It can also be sold by the wandering trader, but at huge prices. (although if you get the galactic luck of finding a blueprint, you can make it yourself). This is the strongest metal in the known world.
-Atlateean Steel, the mystical metal used by the lost civilisation of Atlantis. This one has a tough manufacturing process, but with it you can make the strongest armor, as well as the real trident, monodent and Poseidon's trident.
-Poseidon's trident, which is the strongest weapon in the game. It can also be thrown, although the best it is used as a melee weapon, with its OP damage and speed attack. But you'll need the Heart of the Sea for this one.
-Spears, in its three variants: normal (flint), iron and self-inginiting (flint&steel). All of these deal a bit more damage if throwed, but they also do good damage as melee, especially for a starter's weapon. (sorry if the spears aren't as big as you may have expected)
-SIS Crossbow&Laucnher. SIS stands for self-igniting systems, which means that both the crossbow and the laucnher launch self-igniting arrows (crafted with feather, stick, flint&steel and redstone dust). Both of these are prefabricated, meaning they don't need ammo, the ammo is needed for them to be initially crafted and thus they don't need ammo. Neither of these deal as much damage as bows/crossbows, but their true use is that whatever entity they hit catches fire.
This mod is especially entertaining if used in servers, so I'm considering making the official server for this mod myself, if I see enough downloads.
And that's pretty much the mod adds. Don't be shy if you want to tell anything, really anything in the comments. See you
