Harry Potter and the Deathly Hallows - Part 1

This trophy is fairly easy to get. The Elixir of Life is somewhat hard to discover, but can still be found easily, as the potions that enemies drop are randomized. You must use each of the four potions assigned to the ,, and buttons (by successfully hitting an enemy with it), as well as drink every potion enemies drop on the ground, totaling eleven potions overall. You must drink all of the drinkable potions and use the four equippable potions.

The following potions must be successfully used:
-Garrotting Gas
-Doxycide
-Exploding Potion
-Peruvian Instant Darkness Powder
-Felix Felicis
-Strengthening Solution
-Fire-Protection Potion
-Murtlap Essence
-Blood Replenishing Potion
-Elixir of Life
-Polyjuice Potion

This trophy also MUST be done in a single playthrough to work. No worries though, as I got it before the game was half over.
