1) Most spells only specify 'within' and never state if something must be 'completely within'. A good example of this is the 'Wall' spell. It says the wall must be within 6" of the caster. The wall itself is 6" long. If only some part of the wall must be within 6" then it can be snaked out 12" away. The Grenade spell is another example, the centre of the blast is within 12" but the blast itself extends outside of range. How are these treated when they do not specify 'within' or 'completely within'. Really, all this needs is a definition as to whether or not within means all parts of what's created or not.
2) Potions with similar effects that don't STATE they are treated the same as a spell (for instance a potion that raises Fight doubling down with a spell which does the same). Do the effects stack? So for instance Strength with Strength or Speed with Fleet Feet?
Thanks!
