Obviously, inner strength can be used multiple times. But Pharmacy also allows you to carry that medkit through the gate into another trial, and not use Pharmacy in that one. So, which is a better perk.
Inner Strength is the stronger perk, but Pharmacy is really undervalued. I would definitely take it over, say, Self-Care.
But the real answer to this question is Bond.
Pharmacy is a fairly weak perk overall.
Inner Strength's main downside is that if multiple people are using it, you might run out of totems to fuel the perk when you need it. Funny thing is, you could also have everyone open all the chests before you can gets yours if multiple teammates are running Pharmacy (and even if they aren't, actually), but it's not even a real issue because... Pharmacy is so weak you don't have to worry about other people running it.
Well, inner strenght is better, but i love running a looting build with pharmacy, plunderers, ace in the hole and sprint burst.
Pharmacy. You can open chests quite fast and the guaranteed medkit saved many situations for me. Then again I know many people prefer Inner Strength.. but it's just not my cup of tea even though it probably encourage people to do more totems and it can also save situations.
Searching chest 5,5 seconds, healing 12 seconds = 17,5 seconds once per game as long the killer isn't a doc or running franklins.
inner strenght: totem 14 seconds, locker 8 seconds = 22 seconds up to 5 times.
in fact you still can find a ranger medkit or whatever without any loot perks.
I ignore the different advantages which come with running one of these perks. It's Inner Strenght.
I'll change my vote to Pharmacy when Quentin gets his face rework.
I prefer Inner Strength, because it's quicker than Pharmacy and you can use it multiple times in a match. Pharmacy guarantees you only 1 green med kit for the first chest.
The changes to medkits from some months ago indirectly nerfed Pharmacy, while before you could get 2 heals from the medkit now you get only 1. That makes it good mostly to hoard green medkits for later use imo.
