It's a plugin that adds the possibility to find scrolls with special powers.
sesens.command.use:
Permission for using the commands.
sesens.command.admin:
Permission for using the admin commands.
sesens.setStorage:
Permission for setting a scroll storage.
sesens.canUseScroll:
Permission for using a scroll.
To start the cycle, type in the chat '/sesens startcycle'.
This does require sesens.commands.admin permission; This defaults to OP.
After this treasures will be scattered in a 600x600 field or more or less.
In the tomb (that spawns between 700x700) you can find a summoner's stone and
with that you can re-summon treasures and the tomb.
