How long should I save bombs?

It probably depends on the clear objectives for each battle and your playstyle at the time, but here are some tips: ・To achieve "finish with a special move," you might intentionally chip away at an enemy's HP with bombs (be careful, Lv3 bombs can deal too much damage) before using your special attack to ensure a clean finish. ・You can also hold down on bombs to see the range they'll clear. Use this to clear obstacles while strategically shifting the totem pieces to connect the colors you need. If you don't have enough of the right colors: It's luck-dependent, but try to clear unnecessary colors on the board to intentionally swap out the totem pieces. ・For advanced puzzle players, you can aim where bombs appear, gathering them towards the bottom of the screen to intentionally trigger a "break bonus" by combining two Lv3 bombs. (The more bombs that are active when this happens, the stronger the resulting attack will be). These are roughly the three main ways to efficiently use bombs when many appear. I think how you use bombs is also a matter of preference, so if you don't want to overthink it, you could set a personal rule like "use immediately when Lv3 is ready" if there's no specific battle objective, to use them before they stack up too much. Try to find a bomb-using strategy that works well for you! (｡-人-｡)

When my team's HP is comfortable, I try to gather them as much as possible at the bottom or edges and merge them. Rather than doing it bit by bit, I prefer a big 'boom!' that clears everything at once, as it's high in attack power and satisfying…💦 I think it's ideal to achieve this when the enemy's HP is about two-thirds remaining. Also, being able to merge up to level 4 is a big plus for entering the 'Rampage Slash' time in one go! For example, if you enter 'Rampage Slash' time with various sizes of bombs accumulated and clear the annoying ones in the gaps, the bombs will gradually shift and merge, and if you're lucky, you might be able to reach level 4 in one turn after the fever ends → leading to the next 'Rampage Slash' time… Even when your ally's HP is critically low and you can't take another hit, bombs don't consume turns, and if you have enough of them, you can enter 'Rampage Slash' time, which also serves as a safety measure. It's hard to pull off consistently since it depends on the luck of which colors fall together, but some characters have skills like 'Change to ○ color,' 'Match ○ colors,' or 'Create 1 bomb,' so mass-producing bombs with those skills is also an option!
