How to make a weapon stronger, weaker, or the defense boost it gives you. (This is the same for armor.)
Startup)- Open up your private server files. Now, go into your config folder, and open up 'item.cfg'.
Step 1)- Find your item's ID.
Step 2)- The first block is item id's, the second block is the name of the item, and the third block is the description of the item. Editing those wont do a thing.
Step 3)- The fourth block and the rest of blocks to the right are the weapons stats.
The fourth block - Attack
The fifth block - Strength
The sixth block - Defense
And the rest are magic, range, etc. I can't remember which order they were in. These may be wrong, but that is how I remember them (I haven't edited a weapon or armor in a long time..).
Note: If you want them to a 1-hit KO, then put all of the blocks (Except for the 1st, 2nd, and 3rd) at 99999999
