Magic and Alchemy are essentially the same system, with a few key differences (explained later)
There are two WIT skills:
Magic
and
Alchemy
At character creation, you are able to learn a # of spells = 2 X (# of dice in Magic or Alchemy) You may learn more by finding them in spellbooks, researching them, or finding old scrolls
When using a potion or spell, you roll a # of dice equal to your WIT + (Magic/Alchemy), and if you exceed the TN (Target Number) of that specific potion/spell, it means you either brewed it correctly or cast it correctly.
Key Differences:
+ Alchemy incurs NO penalty to casting if a Potion TN roll is failed
- Any time a Magic TN roll is failed, the caster receives a -1D penalty to all casting rolls until rested
- Alchemy must be carried in vials, and as such must be PREPARED AHEAD OF TIME (and sometimes requires rare reagents other than those supplied in an Alchemist's Kit)
+ Magic sometimes requires reagents, but can always be cast without preparation (unless specified)
- Any Alchemist can carry only 10 vials on their person at any time.
+ Magicians need only worry about carrying reagents
+ If an Alchemical TN roll is failed, the spell either does half-damage (if a damaging spell) with NO other effects, or works half-way (Up to DM discretion...IE a Protection from Cold spell protects only 25% from cold rather than 50%)
- If a Magic TN roll is failed, nothing happens.
