I'm trying to get all XS ranks in hard mode (Trauma Center : Second Opinion) And wow... Triti is killing me! I just can't deal with it. I already watched the tutorial video for Triti, but I couldn't understand that... The only thing I got is that they regenerate if there are two thorns in a row, but I just don't get it!! gosh... This is stressing me out!! man.. when am I ever going to get this?
