  Spell Research System

The time taken to perform research is always unpredictable. It takes two weeks just to get organised and a further one-week for each failure. Once a successful result has been achieved then the Mage may still wish to continue their efforts in order that the spell may be further refined: in this case Failure results (other than Total Failure) are simply treat as no further result. Having a competent research assistant may reduce this time by up to 20%.

Assuming that the new spell is well founded the chance of success is given by the following formula:

{Researcher Specialism Level + 1} x {Mage's Level + Int-9 + (1=Spellcraft) } / Spell's Level

The Mage now rolls a d20 and adds this to the value calculated above, before consulting the following table. A score of 20 or more indicates a good result, but a roll of 1 always indicates a Total Failure.

Spell research costs 50 GP per week per spell level. Additionally the Mage requires exclusive access to a laboratory, these cost about 1000 GP per spell level to set up. This is a one off cost and existing labs may always be upgraded.
