It really came down to Shayd being able to stun 2-3 times early on so that you can kill the two drakes at the top WITHOUT taking damage from the boss. Once those drakes are safely eliminated, it is smooth sailing for the rest of the battle (at least it was for me).
Out of all the heroic bosses I've fought so far, this one was the most luck-dependant.
ALSO: it helps if you figure out how much damage Veleno deals with his skill, and make sure Blood can survive one of them. My Blood took a shot from Veleno's skill shot and survived with about 5% HP remaining (I had built his skill defence and HP just high enough to survive the blast). This way Blood is low health and can deal TONNES of damage.
