Ideas floated a long time ago and locked in Discord hell since. Archiving it publicly.
The idea is for some flowers to be able to be put into a B-side mode where its requirements get much harder, but the mana output increases in conjunction. Either in an addon or in Botania itself.
From Zach:
Endoflame - Plant it on top of a furnace (bonus if it's a blast furnace) and it makes mana while the furnace is running (wow I bet nobody has thought of doing this before)
Entropinnyum - Generates mana when nearby items are destroyed by explosions, with a bonus for variety
Gourmalilis - Just nerf the base output and make it operate more like a rafflowsia, rewarding large cycles
Hydrogaengas - now sponge up water they consume
Kekimurus - now consumes cake even when internal buffer is emtpy. also doesn't work near pumpkin stems
Munchdew - the munchdew produces less mana overall, doesn't take digestive breaks, and has a vastly increased buffer. When the buffer runs out, it decays.
Narslimmus - Now requests slimes in Big-medium-small order (like spectrolous), dumps buffer when fed something wrong
Rafflowsia - Now only consumes generating flowers, producing mana proportional to the mana in the consumed flower's buffer times a function of the cycle length (with potential for shitloads of mana for a full cycle)
Rosa Arcana - now gains full mana from enchantments and XP orbs, but can't produce mana from players.
Thermalilly - turns consumed lava into water
There's more but I can't bother to dredge them up to post here.
