Since most bosses are based on its mob counterpart (ex. pig -> nightmare werepig, bee -> queen bee, rabbit -> wrathful rabbit), I thought it would be fun to speculate some of mobs that could potentially be turned into a boss. Here are some ideas:
1. Monkey -> Moon Quay Island Boss: A boss encounter triggered by interacting with an unnatural portal
2. Tallbird -> Mutated Tallbird Variant: Tallbird variant that have small chance to mutate from teen tallbird. Not really a boss but might be interesting to have a mutation in DST!
3. Lureplant -> Lureplant Boss: Feeding it pure brilliance could trigger a transformation, but it would require restrictions, like only allowing it to turn into a boss on certain terrain.
4. Bird -> Skyborne Boss: A boss summoned by crafting a special item from feathers
5. Catcoon -> Deciduous Forest Hunt: A boss triggered by hunting a suspicious dirt pile in the deciduous forest
6. Ghost -> Graveyard Boss: Summoned on full moon at graveyard with lunar rift open. Boss can only be encountered when certain conditions are met
Would love to hear other people's ideas too!
