Petri's Philter
The Witcher 3 Remastered Potion
Increases Sign intensity. Extended duration. Signs always apply their special effects.
Petri's Philter is a potion in The Witcher 3 Remastered with 3 tiers: Petri's Philter, Enhanced Petri's Philter and Superior Petri's Philter. It spends 25 toxicity while it runs, for 30 seconds at base and 90 seconds at the top tier, and carries 3 to 5 charges.
At its top tier it adds +25% sign intensity while active. Like every potion it counts toward the toxicity maximum only while it runs, and everything active must stay under the toxicity maximum. Every level of a slotted Alchemy skill adds +2% potion duration.
