We investigate catalysis induced by a dyonic impurity in the metastable vacuum studied by Kachru, Pearson, and Verlinde, which can be relevant to vacuum decay in the Kachru-Kallosh-Linde-Trivedi scenario. The impurity is a D3-brane wrapping on S3 in the Klebanov-Strassler geometry. The effect of the D3-brane can be encoded in the world-volume theory of an NS5-brane as an electromagnetic field on it. As the field strength becomes large, the instability of the vacuum increases. As a result, the lifetime of the metastable vacuum becomes drastically shorter.
