The issue is that normally, the Inner Quiet stack is from the actual Inner Quiet buff itself, causing almost all Touch actions to generate a stack.

The only way to clarify it would be remove the effect from Inner Quiet itself and instead put the text: "Additional Effect: If under the effect of Inner Quiet, increase its stack by one (up to 11)" onto every touch skill that is relevant.

Then on Precise Touch you'd then use "Additional Effect: If under the effect of Inner Quiet, increase its stack by two (Up to 11)"
