Clair Obscur: Expedition 33's Game of the Year update brought an even tougher version of the game's toughest boss, Simon The Divergent Star. However, the additional visuals and weapons that come with the update mean that one talented streamer has already figured out how to take down the new and improved Simon with a single punch.
BltzZ went to work right away when the update went live, combining shots and creating builds that would be the most effective against Expedition 33's upgraded Simon. With no weaknesses and the ability to wipe your party with a single blow, even before the update, Simon was about as powerful an enemy as there is on the continent.
How to hit Clair's upgraded Simon with 1.1 billion damage in one hit
The idea that Simon has somehow become even more formidable than someone like me, whose builds rarely accumulate moves beyond the unlimited 9,999 damage you can deal in the first two acts of the game, is pretty terrifying. Not to BltzZ though, who already has a Maelle that can drain Simon's health bar in a single move.
Using a gradient charge and with Fortune's Fury applied so that she deals double damage, Maelle hits Simon with Burning Canvas in her Virtuose Stance, increasing the damage by an additional 200 percent. Burn is already stacked to 116 on Simon, meaning that after doing just one damage to Simon for the first four Burning Canvas hits – all of which mark the target – when Maelle hits the enemy a fifth time, she brings the hammer down for real.
The 10 hardest bosses in Clair Obscur: Expedition 33
Clair Obscur can be challenging, but these bosses are on another level.
So much so that the fifth and final hit deals poor Simon more than 1.1 billion damage. 1,105,130,342 to be exactwhich, despite Simon's big old health bar, is enough to wipe out all of his HP in a single move. Impressive, but BlttzZ notes that with practice, that number can almost certainly be even higher.
Maelle's new and improved move can deal as much as three billion damage
They note that when used against other formidable foes, the damage dealt in a single hit with this Maelle build can top three billion. Maelle's shields can help increase that 1.1 billion to almost three times as many, but since you can't use shields against Simon, it's not possible. When you beat The Divergent Star by more than 1.1 billion without them, it doesn't really matter, and anything beyond that would just be showboating.
Expedition 33's “Thank You” update has more than just a formidable Simon boss fight solely targeting Clair Obscur disease. Versos Drafts takes place in a completely new, unexplored area. There's more story to uncover, secrets to reveal, and boss fights that don't require builds that will cause damage in the billions. There's also a new easter egg waiting to be discovered in Gestralbyn, but I won't spoil what it is for those who want to go find it themselves.
