tavern

[Lord Sauron]

Hello everyone,
i'm playing castlestorm on tablet and I have one question:
what's the exact role of the tavern or brewery? i mean it's said that "it increases the initiative" but i'm not sure to understand what it exactly means...
note that i actually play in french so it could be a translation issue

[Apollo13]

Hello!

If you increase this number your troops "first attack chance" will be increased.
