Bubbles

Many principles create or affect bubbles of radius 5ft. A gramarist can create bigger bubbles by preparing principles multiple times like any principle, but there are certain benchmarks that must be met to create a larger bubble:

Bubble Radius Minimum No. of Preparations
5ft. 1
10ft. 8
15ft. 27
20ft. 64
25ft. 125

And so on in that fashion. A bubble can actually take any shape you like that would fit into the bubble of the appropriate size, but you still need to prepare the principle enough times to create that volume of effect. Essentially, you can always choose to have the bubble fill less than the full volume of the bubble if you like.
