There's been a bit of confusion and speculation, so to make it clear: YES, you can silk touch spawners. (Elite+) Getting your spawner back does NOT require the silk touch enchantment. (see https://www.ecocitycraft.com/forum/...ire-silk-to-drop-spawners.176513/#post-984547) In the NETHER, you CANNOT silk touch spawners. They will break. You will get back the spawner even if you break it on someone else's island. You can only place spawners on your island or an island in which you have coop status.
