For The King

Candies are stat-increasing items tied to damage and defense. To unlock this trophy, your party (which includes you and other players if you're playing together) must consume 10 pieces of candy. It only starts tracking from when you start playing, so if a friend has eaten 9 and then you eat your first, they would unlock the trophy and you'd still be at 1/10.

Consumables that count toward this trophy are:
Black Candy, which offers +1 physical damage
Spirit Taffy, which offers +1 magical damage
Salty Jawbreaker, which increases your physical defense by 1
Honeyed Sponge, which increases your magical defense by 1
Rogue's Brew (surprisingly), which increases your evasion by 2
and- Snickerdoodle, which restores (not increases) health by 5

*Author's note: Written as a catch-all from the game's wiki, I included Rogue's Brew and Snickerdoodle, but I wouldn't think that they would be involved in what you would consider "candy". Chances are this is tracked across all campaigns through your file so don't fret if it takes you a few campaigns to find enough candy rather than buying them.
