Estimated Clear Time for Action Quests

Currently progressed to level 141. Difficult stages: 40, 100, 134. Ads start appearing after level 50. Overall difficulty slightly increases after level 100. Without items, it's hard to maintain the sequence or clear without bursting two blocks consecutively (for level 100, I've posted the clear order on PlayPick). All stages can be cleared without items. However, for a faster clear, using items appropriately in the aforementioned stages is a useful tip. Up to level 100 can likely be cleared in a single day if started on a weekend. However, after clearing level 100, the Action Quest starts a countdown for both reaching level 200 and level 400 simultaneously, and you are given 4 days. Therefore, it might be better to slowly level up to 100 on weekdays and then try to clear up to 400 over the weekend.
