I had a thought earlier today - it would make a lot of sense if Cruentus occasionally gifted you powerful weapons. For game-balance reasons this could might not be great, but what if prayers caused him to occasionally dropped a random mirrored weapon with a high enchantment bonus?
Though, I'm wary of giving Cruentus too many abilities. Just making him more likely to enchant your weapon alone would make him a lot more useful.
As for other gods... Hmm... Time for a checklist. All opinions are my own, take them with a grin of salt; this is mostly meant to spark discussion:
Valpurus:
SPOILER ALERT. Click here to see text.Fine as-is. Perhaps tweaking him to not gift valpurium shields if you already have one would be nice. Although, not super appealing as in order to make use of his gifts you have to learn to use a sword and/or shield.
Legifer:
SPOILER ALERT. Click here to see text.With the above-discussed modifications, Legifer will get substantially more useful. Moves him away from the short-term-benefit theme of Lawful that Fejoa mentioned.
Atavus:
SPOILER ALERT. Click here to see text.Just fine. Though he doesn't help you too much on your typical prayer, gifts of arcanite plate and treasure chests make him an attractive god in the early/mid game.
Dulcis:
SPOILER ALERT. Click here to see text.Here's where discussion happens. Dulcis is boring as crap. Currently only useful if you need to tame someone in a pinch. Suggested improvements:
-Dulcis trains CHA (Ighalli)
-Dulcis gifts expensive artwork
-Dulcis spawns beds for the player
Seges:
SPOILER ALERT. Click here to see text.Mostly OK. Solves the food problem rather satisfactorily and quite easily. If anything, a gift of a Horn of Plenty (item suggestion from the early Ideas thread; periodically creates edibles) would be thematic and useful.
Sophos:
SPOILER ALERT. Click here to see text.Not especially great IMO, but not completely useless either. Emergency teleports can be handy, especially if liquid consumption is modified to make healing potions no longer useful in combat. If improved, maybe she could short-range magic map?
Silva:
SPOILER ALERT. Click here to see text.Semi-useless IMO, but others seem to like her. I hate the earthquake ability and am not a fan of her wolf-hordes. I can see how the wolfpack can be useful in distracting spellcasters, however.
Loricatus:
SPOILER ALERT. Click here to see text.Just fine. Power wanes in the middle-game as the player moves away from the ferrous materials towards more exotic types, but he remains useful for repairing broken gear.
Mellis:
SPOILER ALERT. Click here to see text.Incredibly useful all-game-long, especially if you can keep up a steady supply of bottles and cans. Would be even more useful if you could dump those pesky and ubiquitous bottles of sulfuric acid out.
Cleptia:
SPOILER ALERT. Click here to see text.Extremely useful. No tweak needed.
Nefas:
SPOILER ALERT. Click here to see text.Not my personal favorite, though she gives some great pets. I dunno, I'm just not a fan of pets...
Scabies:
SPOILER ALERT. Click here to see text.I pretty much never pray to her. I don't her giving all those tasty-corpses-to-be leprosy! Suggested improvements:
-poison weapons (Kangaroo)
-fart clouds (Kangaroo)
-lycanthropy/vampirism (Kangaroo)
-ring of unchanging (Ighalli)
-polymorph nearby enemies into sheep
Infuscor:
SPOILER ALERT. Click here to see text.Probably OK, he already gives some powerful status effects, and now lights people on fire too.
Cruentus:
SPOILER ALERT. Click here to see text.With Ighalli's suggested tweaks I think Cruentus will be just fine. Previously he was just a handy source of troll blood and Mortifer piety.
Mortifer:
SPOILER ALERT. Click here to see text.Probably fine.
