Reactors are the interactive props scattered through the world: the crates around Amherst, the plants in the Ellinia woods, the coconuts on Florina Beach. They are not monsters and they do not fight back, but most of them break apart when attacked and can leave something behind.
How they work
A reactor moves through a fixed series of states. Every hit advances it one step, and when it runs out of states it breaks and disappears. Most take three or four hits. After breaking it returns on a timer set per prop, anywhere from 30 seconds for a coconut to a full hour for the box in the Magic Library.
Nearly all of them respond to a plain attack. The witch's herb is the exception: it ignores attacks and has to be triggered with an item instead.
List
| Reactor | Hits | Activated by | Respawn (s) | Maps |
|---|---|---|---|---|
| 3 or 4 | Attacking it | 30 to 360 | 6 | |
| 4 | Attacking it | 60 to 600 | 5 | |
| 3 | Using an item | 60 to 1200 | 10 | |
| 4 | Attacking it | 60 to 120 | 13 |
Where to find them
The boxes stand around Amherst, with one more away from the village in the Magic Library. A further box sits aboard the Cabin (To Orbis), on the ferry route that does not run at Grand Launch. The flowers fill the woods north of Ellinia, thickest in The Forest North of Ellinia. The herbs cover the swamps and croko fields south of Sleepywood, and the coconuts hang in the palms along Florina Beach.
The Zakum altar
Not in the game at launch. This article covers content that is confirmed and was playable in the second Closed Online Test, but which is not part of MapleStory Classic World at Grand Launch on October 21, 2026. Nexon has said it will be reworked before being introduced gradually, and has not given a date. See Differences from MapleStory for what has been confirmed so far.
One further reactor is not breakable at all. A carved stone face the height of several characters stands on The Door to Zakum in Ossyria, jaws open around a dark opening. It has no hit sequence and never respawns, since nothing about it is destroyed.
