Wisdom / Folly
When it is flowing · Wisdom

You act with a clear head. When you set a boundary or push hard for something, your judgment guides the force, so your firmness protects what matters instead of bruising it. People feel your strength as something safe to be near. You can be sharp when sharpness is called for, and it comes across as wisdom rather than aggression.

When it is strained · Folly

Your force outruns your judgment. You push, cut, or defend, and only afterward see that the timing or the aim was off, and something got damaged that you would have wanted to protect. Boundaries come out destructive when you meant them to be clean. The strength is real, but it keeps arriving without the discernment that would let it land well.
