Forgotten Tales

I know for the "6 health potions" quest you need to bring 6 different types of potions. I feel like I'm missing something really obvious here, but I can only find 5 types: 25hp, 50hp, 250hp, 500hp, and 1000hp. I've read there is a 100k hp potion somewhere that is not specific to a quest, so could someone please let me know the simple thing I am missing? (4 mana quest was easy and I'm not even a mage needing to pay attention to those things.)

Thank you.

Not sure about the 100K potion.

Spoiler: Show

Missing the +100HP potion. Mummies in dungeons 111 and 124 drop (25%)

That seemed like the logical potion strength I was missing. Thank you, I had not been to either of those locations for awhile!
