Who in their right mind would make a weapon out of lead or magnesium? Honestly there are better things to work on than new materials at this point. Try coding some interesting new items instead.
I bring a new bill to the Senate floor today, for all IVANers to hear and vote upon.
Section I-
IVAN is not, and never will be, Nethack, ADOM, or Dwarf Fortress.
Section 2-
IVAN will not copy elements from any of the aformentioned games unless it is of critical importance, such as the ability to move your character with the keyboard.
Meh, a limb-changing monster just sounds like it would be frustrating as hell. IVAN doesn't need random WTF deaths, it needs deaths where you say "Damn I should have played that better."
I like the lantern idea. It could show invisible enemies/mines in its glow. Could be cool.
And I 100% agree with no magic. We debated this, along with the inclusion of ranged weapons, a long time ago and the consensus was that they don't fit in well with IVAN gameplay.
You must use your fists as your weapons.
No gloves may be worn.
Everything else can be worn but it HAS to be leather.
You can only go to + alignment, so no chaotic gods.
You have to read every single thing you find when you find it. Books, scrolls, etc.
Vermis is, in my opinion, the best weapon in the game. Not only is it fast and deal heavy damage, but it also gives you telecontrol, teleportitis (teleports you every now and then) and can teleport your enemies.
Also, lightning usually only bounces off walls. You might just be getting lucky.
