Swarm of Bats Gaining Power

By wraith428, in Warhammer Invasion Rules Questions

Quick question.

Was playing a game last night and Swarm of Bats came out. My opponent and I differed on how we think it works. I think the Swam attacks for 1 power + 1 power per monster revealed. My opponent believes the Swarm's power is replaced by the number of monster's revealed. Since Swarm of Bats says "gains" I think its in addition to the 1 basic power. Additionally Warpstone Experiment uses the gains word and gives 3 power for comparison.

We played it my way but decided to post and see how other people are playing it.

Thanks,

It gains hammers in addition to its printed power and any bonus it might have had at the moment.
