increase chance to encounter Shasshhiy'Kaish in Daikara, for lazy unlock doom elf

EDIT - I'm thrilled that this actually became obsolete less than a day after putting it up. I'll leave this up in case someone needs it (I guess if you like the cultists and don't have Ashes this should fix their spawn rate for you too).

This fixes the spawn chance of the Cultists/Monolith event needed to summon Shasshhiy'Kaish and complete the Doom Elf unlock
