Bloodlust is a skill that was once exclusive to Gladius cards. When Chaos Legion came out the first card that had Bloodlust was the airdrop, Grum Flameblade. Indeed with four melee attack, five shield and 10 hearts at level one, he is a powerful tank. The only downside to Grum is his one speed that can cause him to miss.
Recently a new reward card has also been granted the Bloodlust skill, Jared Scar. Being a reward card, he is a very cheap tank to get this skill.
Now for a sample game. Here I have a level 4 Tarsa against a level 5. My opponents cards are at a higher level than mine. My team was wiped out but Grum singlehandedly won the fight.
