When activated, the release of blood from the target with your attacks gives you enthusiastic adrenal rewards and the way the adventurer focuses their battle chi energy results in an increase in Health Points. The bonus is dependent on the training and the amount let by the critter. For example, Rank 1 will give a 10% return with an increase of +10% of your own Health Point max. and Rank 5 will give a 50% return with a +50% to your blood maximum. The blood will drain fast, as if your are poisoned/bleeding/diseased, thus you may lose a good bit of it at the end of a round. That could work with an inverse set of Rank related numerics such as -50% drain per round at 10% return and -10% drain per round at +50%. When the same critter strikes at you, they will always take some of the character's 'real' Health Points on top of the Bloodlust related pool. If the character has bleeders, it will always suck from the Bloodlust pool with the same inverted ratio as the drain per round.

Now for the real fun part! If the Warrior triggers Berserk, then the Bloodlust pool will directly feed the damaging power of the Warrior's strikes. So if the Warrior has a 50 Health Point pool running from Bloodlust, the Berserker convert the imaginary health increase into offensive power with damage weighting-- directly taking from the Bloodlust pool and into the damage on the target. It will be a random ratio to drain the Bloodlust pool.

If an ambusher triggers Smastery or has it running when Blust is activated, then they will directly feed on the level of damage initiated upon the target. For example, if the Rogue manages to mangle the leg of the target then the Bloodlust level will be a huge bonus (not quite the most as would be from a Kill or a larger bloodier area such as abdomen and back) and excite the ambusher for a small AS increase-- say +1 per rank possible of Blust. This can work in for Berserk or other uses of combo activators with Manuevers. If there is a kill then the Bloodlust results in a +5 AS bonus (which is reduced by -1 for each 10 HP missing from the max capacity of the Bloodlust pool).
