A few users have brought to my attention that due to yearly resets, buying single spawner keys isn't worth it to some of those who are not directly competing against other top islands. As well, some people simply want something more permanent.
We cannot of course regenerate all spawner key purchases on SkyBlock resets (every January) due to the fact that it would basically ruin SkyBlock when it comes to those who have bought a large amount of keys already giving them a massive advantage right off the bat.
The solution we have come up with is the Monthly Spawner Upgrades.

Basically, a monthly spawner upgrade costs 2.5x that of a single spawner key, however, the upgrade carries with you forever, across every yearly reset, etc. Once you have it, it never leaves your account.
We will still sell single spawners of course for those who want that extra boost if they are on a cooldown, or don't have a monthly spawner package in their account.
