nightmare attacks can be predicted,but it is hard...you can counter his boomerang,spear attacks using Rolling Blaze attack..however,timing must be perfect...
if you able to do it,he is open to attack.unleash Kick-13 and Inferno in D.T. form if possible.this technique also applies to DMD mode...
Nelo Angelo on the other hand,is almost unpredictable.He can switch his attacks between sword fighting,hand to hand or etc...His counter attacks are powerful even in Normal Mode.
In DMD mode,his Summoned Swords are deadly and he will use it every time if possible.His attacks are easy to dodge,but if connected,you are in big trouble as he will make a combo attacks.
His attacks can be deflected with proper timing.The easy way to kill him is use Ifrit.Alastor's attack power is too low even in D.T. form.However,you can use Alastor D.T form to recover some health.His unblockable attack is the uppercut attack which is VERY dangerous.If you see this attack,run as far as you could.
When he is open,use Kick-13 in D.T form to kill him faster.:lol:
