gimmeh a code review on this ```        // Check for three items in the anvil,
        ItemStack slotA = event.getInventory().getItem(0);
        ItemStack slotB = event.getInventory().getItem(1);
        ItemStack slotResult = event.getResult();
        if (slotA == null || slotB == null || slotResult == null) {
            return;
        }
        // Neither is enchanted.
        if (slotA.getEnchantments().isEmpty() && slotB.getEnchantments().isEmpty()) {
            return;
        }
        int resultLevel = 0;
        for (DHEnchantment dhEnchantment : DHEnchantments.all) {
            // Both, then A, then B
            if (slotA.getEnchantments().containsKey(dhEnchantment) && slotB.getEnchantments().containsKey(dhEnchantment)) {
                int aLevel = slotA.getEnchantmentLevel(dhEnchantment);
                int bLevel = slotB.getEnchantmentLevel(dhEnchantment);
                // If both are the same level, then if they are not.
                if (aLevel == bLevel) {
                    resultLevel = aLevel + 1;
                } else {
                    resultLevel = Math.max(aLevel, bLevel);
                }

            } else if (slotA.getEnchantments().containsKey(dhEnchantment)) {
                resultLevel = slotA.getEnchantmentLevel(dhEnchantment);

            }
            slotResult.addEnchantment(dhEnchantment, resultLevel);
        }
        // If it is still = 0, it means that no custom enchants actually ran.
        if (resultLevel == 0) {
            return;
        }
        event.getInventory().setMaximumRepairCost(50);
        EnchantmentsHandler.getInstance().rebuildMeta(slotResult);
        event.setResult(slotResult);```
