Begin by dashing in close to Slogra, waiting just long enough for Slogra to begin his spear attack. Immediately dash away 3 times as Gaibon swoops in closer to you and the ground. Punch Gaibon a few times, then move to the right as Gaibon flies up and away from you, lining yourself so that you are close enough to punch Gaibon as he lands on the ground. Slogra should be behind Gaibon at this point. Keep punching Gaibon until you hear him enter his second phase. Pull out your shield to block Gaibon's diagonal fireballs, then perform a Hellfire while holding RIGHT so that you travel far enough to line up with both Slogra and, as he lands, Gaibon. Hold UP at this point to upgrade your Hellfire attack into the flaming orbs. If performed correctly, Slogra and Gaibon should both die without granting Alucard any XP.
