am confused is new + just more damage to me and faster bullet rate. my strategy was buy the luck, then 15 damage, some points in javelin, then max armor, just saved up two runs and had it, than killed all the bosses with the starter weapon used the invulnerability potion when ever possible in the boss rooms, you can recharge the potion rather fast with a dodging for a little bit if it needs a little more and thrown javelins. potion could be used about every two to three rooms attack the green first.
