I've spent countless hours refining the full auto crossbow build in Sineus Arena, and honestly, it's one of the most fun and effective setups I've tried. The key is to combine rapid-fire capabilities with high crit chance to maximize damage output. During my gameplay sessions, I noticed that timing the shots carefully when facing tough enemies like the final boss can turn the tide completely. One thing I appreciate about this build is how it synergizes with the Candle Knight character, who benefits from precise, rapid attacks. When equipped with the UZ.22 attachment, the crossbow becomes nearly unstoppable, leading to frequent critical hits that make bosses melt away faster than expected. I also learned that although this build is considered 'broken' by many due to its overwhelming effectiveness, it does require a good sense of timing and positioning to avoid being caught off guard. For instance, during some battles, I found that constantly moving and screwing with enemy patterns helps maintain an advantage. If you’re into builds that offer both speed and power, this full auto crossbow setup is definitely worth trying. Just remember, like any build, it has its weaknesses, so always adapt your strategy according to the opponent and environment. Happy gaming and may your crits be ever in your favor!
