They need a jungle themed branch, or rework the Lair to be more jungley. Fedhas is pretty worthless, though Sunshine/Flood are VERY useful, especially against EELS WHY ARE THERE EELS!!!
And for the exorbitant price of
two whole grapes, you can summon a friendly oklob plant that lasts forever and grants you the experience from its kills. Obviously not worth the expense. And granting you an ability that one-hit-kills all ghouls or necrophages, while
granting you piety for doing so.
Mind, I haven't played the latest version yet, so they may have changed the thing about having a single raisin be worth just as much as a whole grapefruit as far as Fedhas abilities are concerned. And before, you could still use those abilities even without fruit, you just had to cough up some piety for the privilege.
Fedhas gives you so many methods of making yourself safe, it's not even funny. You can surround yourself with water, block off passages with plants (that you can still walk/shoot through), or even turn an entire dungeon level into a safe haven through good use of the "reproduction" special ability, which causes friendly giant spores to erupt from nearby corpses. They wander around until they find an enemy to blow up on, at which point they create a number of neutral (don't give you experience for kills, unlike the first generation of spores) ballistomycetes, who will periodically spawn more neutral spores for as long as they remain.
Eventually, more and more spores will be generated and will explode on whatever they find, causing more spore-production facilities to spring forth. After a while, the entire level will become a forest of passage-blocking mushrooms (that you can walk through) and kamikaze spore packs who will attack any enemy creature that dares wander in (note: While they may not choose to attack you, that doesn't mean that you're exempt from the collateral blast damage. Keep a safe distance).
It should probably be stated that this is all information based off of when I was mucking about in 6.0 Trunk. It's quite possible that some, if not all, of the information stated here has changed to some extent.
