Since this is obviously a vital part of the game, hot draconium ingots should inflict heat damage while held, similar to the other GT hot ingots. I have prepared a script for this:

hotdraconiumingot.onItemUpdate = function(itemStack, world, owner, slot, isSelected) { owner.attackEntityFrom(<damageSource:heat>.setDamageBypassesArmor(), 3.0); return; };

Which should go just before hotdraconiumingot is registered in ContentTweaker.zs.

Additionally, stack size should be reduced to 16, to match that of other hot ingots.

Implemented here #258
