All Talia al Ghul Attacks (Phase 1)¶ This section will detail all of Talia al Ghul's attacks during the first phase. She wields a katana-like weapon and a bow. She will also occasionally use throwing knives when you're not in melee range. Fast Sword Attack¶ Talia's strength comes from her sword fighting prowess.4.1 Level 1 For Phase 1, you will not inject new code. Instead, your exploit string will redirect the program to execute an existing procedure. Function getbuf is called within CTARGET by a function test, which has the following C code: 1 void test() 2 {3 int val; 4 val = getbuf(); 5 printf("No exploit. Getbuf returned 0x%x ", val); 6}Phase 1 is the easiest of the 5.
