Oasis

Strategies
Oasis appear during events on Lake tiles in Desert maps, where you will be given the option to let them drain some or all semen from your party. Giving the Oasis some semen will grant +2 max morale to the party, +10 morale to all characters, and 10 food. Giving all of your semen will grant +5 max morale to the party, +20 morale to all characters, and the Oasis will join your party. Requirement for donating "All" not fully confirmed, might be related to amount of Male/Futa characters in party (Tested with 80% Male/Futa, could recruit) or total amount of semen among party members (Tested at 20+, could recruit).
