A strong move costs energy and magic together, and the game takes one and then fails

When one action needs several resources, taking them one after the other can leave the player poorer without the action happening. Here is a payment that either takes everything or nothing, says exactly what was missing, and can offer a painful alternative.

Why this works

A cost is a promise: either the whole move happens or the player keeps everything. Checking first and changing once means no half-paid move can ever exist, and the exact shortfall tells the player what to fix.

When not to use it

Skip it when partial payment is part of the fun, such as a spell that fires weaker with less power. Let it use what is there instead of refusing, as the charged attack entry does.
