(adsbygoogle = window.adsbygoogle || []).push({}); i just edited it abit so when u hit a 1 u get 1 token instead of random tokens
credits are below

go to npc.java search for

    if (source instanceof Player) {

under that add

    final Player p2 = (Player) source;

		int dmg = (hit.getDamage() * 1); //*1 means if u wanna make it so if u hit a 250 u get 250 tokens

			if(this.getId()==131)    // 131 is the npc id

			p2.getPackets().sendGameMessage ("You have gained <col=FF0000>" + dmg + "</col> " + "damage tokens");

			if(this.getId()==131) 

			p2.getInventory().addItem(13653,dmg);  //13653 is the item u get if u hit a monster in this case penguin. 

    

final Player p2 = (Player) source;

int multipler;

int dmg = (hit.getDamage() * multiplier);

if(getId()==131) {

[INDENT]p2.getPackets().sendGameMessage ("You have gained <col=FF0000>" + dmg + "</col> " + "damage tokens");

p2.getInventory().addItem(13653, dmg);  //13653 is the item u get if u hit a monster in this case penguin.
