Alchemy

You have mastered the art of potion brewing. You gain the following benefits:

• When you mix potions ( On the Potion Miscibility chart in the DM Guide) and don't get the desired effect, you can add or subtract up to 15 to the dice roll (Example: 82 --> 97).
• You automatically know the effects of the mixture. 
• For you, the potion Miscibility chart looks like this:
  • 01 ----------- The potion becomes an ingested poison (DM's choice)
  • 02-05 ------ Both potions lose their effects
  • 06-15 ------ One potion loses its effects (DM's choice)
  • 16-20 ------ Both potions work, but the numeral effects and durations are halved
  • 21-75 ------ Both potions work normally 
  • 76-90 ------ Both potions work, but one potion's numeral effect and duration are doubled (DM's choice), the other potion is unaffected by this
  • 91-00 ------ Only one potion works but the effect is permanent. Choose the simplest effect (DM's choice)to... etc. (see DM's Guide)
