Lowest level Sins of the Father?

Firstly, I’d like to clarify that I am not saying that I am the lowest level CB to have completed Sins of the Father. I am simply asking what the lowest level completion is?

I just completed this quest last night on my 20 def pure at lvl 73 CB. It was my last quest/miniquest to completely fill my Quest Log given my defense level restriction. That being said, this was clearly the hardest boss for me to kill. I am no slouch when it comes to PvM content (although I am certainly not the best). On this account, I completed Jad at 52 combat and Song of the Elves at 63 combat. Once I get a T-Bow (still very far from this) and higher CB stats, I fully expect to attempt Inferno as well.

What makes this boss the most difficult for me at a low level, comes threefold.

1. Firstly, you cannot prayer flick this boss to negate damage. Throughout the first phase of the fight, even with protect from Mage, damage is registered very frequently at low defense. It does not sound like much, but these constant small ticks (between 1 and 8, sometimes 12 with the boss’s “Blood Buff”) certainly add up with low defense and lowish HP. This constant damage ramps up even more in the second phase. I’ve faced similar problems before with the Fragment of Seren, however Seren’s damage nuke is proportional based on your total HP. This means, higher defense/HP didn’t matter as much in Song of the Elves.

2. Secondly, with my character having low attack and low crush bonus, the Blisterwood Flail hits very infrequently. Even at low strength the Flail would pack a hard punch, however the problem was actually getting any damage in the first place. I would often hit five or six 0's in a row before finally getting any damage in.

3. Thirdly, RNG is real. Not only is your damage very RNG, so is the boss’s damage to you, so is the boss’s special attack phase, and so is the entire second phase of the fight. When you fight the boss during the first phase, every 8-10 attacks he will initiate a special attack. This special attack is either a damage dealing blood bubble (that can hurt the boss as well as you), an explosive bloodveld pet, or a nuke that can only be negated by turning away. Being lowish strength, I would often rely on the blood bubbles to do damage to the boss. However, considering that these special attacks were mostly random in their order, the blood bubbles cannot be relied upon too heavily. This RNG continues into the second phase where lightning continually strikes the ground around the boss.

All this being said, I wonder what the actual lowest level completion for Sins of the Father is/could be. Firstly, certain stats are required to do this quest. 50 Attack is necessary to wield the Blisterwood Flail and 49 Magic is required to start the quest. Furthermore, the previous quest chain gives 4,600 defense XP, meaning that at least 20 defense is also required. The required stats being said, I would assume that at least 43 prayer and around 70-75 strength would be necessary too. The boss would shred too hard without protection prayers and your damage output would be too low without a least mid level strength.

TLDR/CONCLUSION:

With 50 Attack, 70 Strength, 20 Defense, 75 HP, and 43 Prayer, you would be 68 CB. So I would reckon that the lowest possible Sins of the Father completion would be between 67-70. Thoughts? Do you think Rendi will make a video on this one, like he did for Song of the Elves?

Here are my stats and setup for finishing the quest at 73 CB. I did pre-pot before the fight as well. It took me around 15ish attempts, I would guess.
