hello , i was farming bosses and i got to this boss , and i had my Pokémon in a substitute , even tho he was in a sub the enemy boss crit and one-shot him anyways

Hello @Ramzi2525 !

First, I'm really sorry to hear about your lose versus this boss.

Unfortunately it is not a bug, Hyper Voice bypass Substitute and crit consider drop stats and do normal damage, here I did a showdown calc for you with -4 (2 Shell Smash Gorebyss) versus a Simple crit Hyper Voice!

Let say, you used 2 Memento before giving simple ability via Golduck, the Sylveon is at -4 (-2 from Memento)

0 SpA Sylveon Hyper Voice vs. -4 252 HP / 0 SpD Gorebyss on a critical hit: 400-471 (127.3 - 150%) -- guaranteed OHKO

You can see there a crit do around +127 damage and kill Gorebyss and since boss have higher stats with EVs, it is a kill at 100%

I can understand it is frustating but it is how Pokemon RNG can be sometime.

I wish you a wonderful day and a Good Luck for your bosses run!

Very Respectfully,

Zarachi

ty very much for explaining it , i didnt know hyper voice didnt account for sub
