Very strong abilities to drain Mana directly.
Light Bugs are all-rounders with heavy emphasis on Mana. They have multiple ways to take Mana from enemies, which they can stock with their very high mana growth, then transfer to allies via fucking. Beyond that, they have an array of possible skills to provide support in many situations.
Their mana growth is the second highest of all the base Hybrid Species, so you could focus on that and breed a Support Level Type. Various skills and traits can also help enhance their strategic support abilities. For example, as their default method of restoring an ally's Mana is fucking, you could complement that with traits like Refreshing and Mending.
