Possibly this, I have not tested nor will I but the npc drops is handled the same way with some servers who have the pker mode.
Go to InventoryOptionsHandler, and search for "handleoption7". If you scroll down you will see "World.addGroundItem(item, new WorldTile(player), player, true, 60);". Try changing it to something like:
Code:
if (player.isIronMan) {
World.addGroundItem(item, new WorldTile(player), player, true, 6000000);
player.getPackets().sendSound(2739, 0, 1);
} else {
World.addGroundItem(item, new WorldTile(player), player, true, 60);
player.getPackets().sendSound(2739, 0, 1);
}
}
This could definitely be done better, but seeing as how I am the only reply hopefully this helps.
