    I'd just create a method that returns an integer and takes an ItemStack within it's parameters.

    To get the blood value, let's say that it is ALWAYS on line 2.

    Code:
    String[] lore = itemMeta.getLore();
String loreLine = lore[1];
    Otherwise, you could iterate through the array until you find the correct line:

    Code:
    String loreLine = "";
for(String line : lore)
{
  if(line.startsWith(ChatColor.GRAY + "Blood"))
  {
    loreLine = line; // you can now use this variable in the later pieces of code
    break; // get out of the loop
  }
}
    You'd also want to split that line as follows:
    Code:
    String splitted = loreLine.split("Blood: " + ChatColor.WHITE)[1];
splitted        = splitted.split("/")[0];
    Let's pretend the lore has a 29/100 blood value, you will now have the number 29 stored as a string value.
    This is where you can simply use the earlier provided method:

    Code:
    int blood = Integer.parseInt(splitted);
    Please note that if the splitted value is not a number then that will throw a NumberFormatException, which you could catch if you wished to tell someone that something failed (or do anything else for that matter).

    Sorry, I thought the ItemMeta#getLore() method returned a String array, it actually returns an ArrayList.
    Change:

    Code:java
    1. String[] lore = ((Player) damager).getItemInHand().getItemMeta().getLore(); // to:
    2. List<String> lore = ((Player) damager).getItemInHand().getItemMeta().getLore();
    3. //and
    4. String loreLine = lore[3] // to
    5. String loreLine = lore.get(3);
