because with weakening and first strike it might as well just kill you automatically.
Basically for both Taurog and TT if you're going pure magic there's no reason not to knock out those alters, and if you're going to be doing any physical attacks then you don't even want to consider angering these deities. This is part of a larger problem I see with the deity lineup currently (this is true of everyone
except Jehora), that either the penalty is so huge that you can never even consider taking it, or it really has no impact on you so the penalty is meaningless.
Presently Mystera and Glowing Guardian stand in a class of their own. Unless you're playing Purist, no one in their right mind can afford to have all their items stripped from them, and taking +15% resists to all monsters is simply nuts. I don't think any realistic character can even consider desecrating either. On the opposite extreme is Binlor which only affects people with resistances, which is relatively few now that the dragonshield is nerfed.
Personally, I think most if not all of these need to change. The penalty needs to stop being so steep for the general-case character, but needs to be harder to circumvent.
For Tikki Tooki, I feel the problem are his two potion boons. The bottom line is: 90% of the time a mana/health potion is better
than the quicksilver/reflex potion. Even in the rare cases where it isn't better, the net gain is so marginal that I'm better off converting to another deity to use that piety elsewhere. Tikki's other three boons are fairly good as is, it's just that he has these two absolutely horrendous ones taking up space.
For Taurog, he's pretty marginal unless you're a Monk or Berserker. Most of his boons simply are not worth the -2 mana tradeoff, and requiring piety and
an inventory slot on top of this makes him a no-go for most classes. Now that Monk no longer has atrocious inventory limitations that may not be a trade he's willing to do either. I really think Taurog needs a complete rework. Right now people who can afford to eschew magic are doing well with him, and everyone else doesn't even touch his boons... which means he's only really used by 2 classes.
I actually think Mystera can be added to the list of gimped gods. Her only good boon right now is mana leak. Magic is way too double-edged for most characters, weakening has always been horrendously overpriced, flames is an insane downside to anyone who isn't going pure-magic, and refreshment is pretty niche (mostly useful for multi-stage bosses). Glyph magnet is pretty lame. Mystera punishes glyph conversion pretty strongly, so there's a lot of incentive to find and convert the majority of them before
you begin worship. While I occasionally use her boons, I use her much less than Tikki Tooki and it's usually as a piety farm with mana leak being my alternative if I can find no one better to convert to.
While we're on the topic, another discrepency I find is the bonus deities give on worship. Some, like Taurog, potentially give large sums of piety when you join their religion. On the other hand, Dracul gives almost no piety, and Mystera literally does nothing. It gets a little silly late-game when Taurog will actually give you enough piety to convert to someone else! This is especially egregious for the Glowing Guardian since high-level characters who have already converted most of the glyphs really have no way to earn piety with him.
