Check for Crystal type.

Simply change the stackType, they have to differ. Call it anyhow you like.

Lmao.. Reading the godamn config you should know it's amount... Plus, you can replace the naming with whatever you like, so..

Frozen as any pack has issues. It's kinda messy, but still works.
Disadvantage, it's not developed since years, but it's perfect for newbies as it has all customs.

Blind?
 
    public static void augments(L2PcInstance activeChar, int ammount, int attributes, int idaugment, int levelaugment)
 
public static void clanReward(L2PcInstance activeChar, int ammount)
 
"ammount", it's hard-coded on the method call > clanReward(activeChar, 20)

Make sure case sensitive is not selected. Otherwsie, letters must match - lower case, upper case, must be exactly 100%.

So, how can you have an error while you didn't build it yet? 
 
Pretty much the same if you have svn, except java version, I believe.

Compare it with another shield xml, you should be able to notice difference, what's missing. 

I already told you where to put htm. Also the npc type must be L2DonateShop as it's an instance npc not script as you said. 

ClassID.java change the ClassType.FIGHTER  to MYSTIC.

Seriously.. All you need is the getIcon mechanism and the sql file with icon path. 
 
Lazy people.

Wrong file, still. Read again what I said above. But ok, this time I will use bold' font with color.
 
I said first and you opened file .. no8. Well, not bad. Here is a picture with order.
 

 
Now, you know where to dig. All you have to do is to READ methods names and replace it with old code - from free svn. Profit.

item.setEnchantLevel(item.getEnchantLevel())  
or simply do nothing inside brackets, no code, no actions.

Compare with L2jserver code and edit if necessary.

Error is clear and you could Google it. Number format exception, your config is "10." while it's supposed to be an int and not a double. So, remove the dot, it must be "10".

It could be  edited client message or message from EnterWorld.java

You didn't get the point. Like set.getInteger("enchantmentLevel", 0); Second parameter is the default value. So, you add the enchantmentLevel value where you need.

Your question isn't clear. 
It's bypass related the the instance type. Npcs with such instance, L2BufferInstance / Buffer, can use the bypass. Check the core, working npc what type its using. 

Read, error look code.. You miss one }

Download l2fileedit.

Npcs are registered under castle.xml or so, if that npc is not registered as giran castle, then.. Shit happens.
 
And ffs, it's acis.

The code color is also reverted.

if (activeChar.isStunned() || activeChar.isConfused() || activeChar.isAway() || activeChar.isParalyzed() || activeChar.isSleeping() || activeChar.isDead()) { activeChar.sendMessage("You Cannot Use Items Right Now."); activeChar.sendPacket(new ExAutoSoulShot(id, 0)); activeChar.setAutoPot(id, null, false); return; } The check already exists, simply remove two/three lines (return is a must) and voila. 
AutoPot runnable method.

You need SVN, then changes will be visible (a black *). Right click on project, team, create patch.
