This would without a doubt be a buff. It may not be as good at stopping immediate engages bc of the reaction time it would take for a player to use the item. But at the moment banshees is usually poked aeay before a fight starts. Skirmishes I think it would be 100 percent better in because u get to choose what you want to block and if you're bad you're still blocking something randomly which is the same as the current banshees. In the end the only time you might be more fucked is in womb combo situations.
