I'm working on a Kasatha Unchained Monk for an upcoming campaign. When looking at the Style Strike, I noticed that the Hammerblow style strike requires both hands free to use, and does double damage dice.
1. Would a Kasatha Monk need two hands free, or all hands free to do a Hammerblow?
2. Could a Kasatha link all four of its arms together to do 4x damage with the Hammerblow? (Probably wishful thinking on my part)
3. Would the damage from elemental fist also increase while using a Hammerblow?
