I know some of you also like making super sims, stacked with every possible hidden and reward trait
From the SimsVIP Island Living guide:
Elementals and offspring to Elementals have the inherited Sulani Mana trait. This trait allows them to use their elemental energy to increase the quality of plants and summon Volcanic Bombs.
Offspring, you say?
The trait, as described, gives the ability to increase plant quality by a full stage at a time as well as summon the same volcanic bombs as a volcano eruption, which can cause fires while hot and be broken to find metals and crystals when cold. The abilities have a long cooldown, which seems to be approximately 18 sim hours.
In order to get a child with this trait, you need a sim with the trait Child of the Islands to Summon Island Elementals. The elementals are randomly generated ghosts and you can befriend them normally even if they give you a bad judgement. If you invite them to your household they will lose their status as Island Elemental, but retain their Sulani Mana trait.
Be aware that 1) you cannot propose to a ghost not in your household, 2) in order to invite a ghost to move in you need very high friendship, almost a full bar and 3) you cannot invite the ghost to move in while the social event Communing with Sulani Elementals is ongoing.
After the ghost is part of the household, it can be resuscitated with Ambrosia (no ghost elemental babies, sadly
) and any offspring will have this interesting trait.
Have fun summoning fireballs!
