I didn’t go through all numbers, but you’re being pretty unrealistic with the 6.5k base atk weapon there. I said 500m back there but that number is way off. His weapon (in the video) is worth more than 50b…
Even if he had infinite money, all the blessed shards you’d need to make your weapon reach max transcend stage would require you to wipe out all blessed shards from the market… several times…
And we’re not even considering the actual probability of success in higher level stages…
His weapon also has not one but three level 8 gems. That’s probably nothing compared to the cost of the blessed shards, but just one of those gems might be worth around the money to max all murmillo attributes (around 60m i’d guess?)…
So… You might be overlooking the extra damage from Slithering / High Kick debuffs and also overlooking skills base atks due to the abysmal atk on end-game weapons you’re considering…
Also, just going to mention his weapon actually has 5k atk and not 6.5k.
I have an Oghma Gauntlet but I think the bonus is only +25% dmg against Leather and it doesn’t really negate the strike dmg to leather weakness. I prefer to use Vubbe Fighter Gloves for extra AoE atk ratio, overall gives me more dps.
