Effect that temporarily adds AC

[D3nnis3n]

Hello,
i try to create my first few effects. One effect i want to create is one that adds AC temporarily, but if i use AC: X, it will SET the AC to that, instead of add it.
What i'm doing wrong?

No, you are on the correct lines.

AC: x adds whatever amount x is to the target AC (whether self or target). To limit it set the time to a number of rounds or minutes or whatever the timespan should be.

My graphic shows an addition of 2 points to the AC for 1 minute.
