Re: beta testers?

With a memory (mm) of 8, there is just enough for a two-ingredient result. Rolling a 17 on the d20 with a 16 in Magery means only 7 traits come true. Players are allowed to repeat traits as ‘sacrificials’ to better their odds. The GM may choose random traits not specified or ‘lost’ by bad roll.
All results will weigh a total of ingredients, so deliberately having too much of a ‘non-whole’ ingredient like sand or water will simply cause the leftovers to stay ‘unmixed.’ Having a 5-lb turtle as an ingredient with a 3-lb Casting Weight will either cancel the spell or cause random effects.
I’ve generally decided a player will know whether weight will be a problem.
A bad spell to come later. This lunch is over.
