This spoiler attempts to describe and quantify the various in-game effects of worshipping ToME's gods -- the benefits and penalties, how to gain (or lose) piety, and so forth. Note that the spells (and access to other spell realms) provided by these gods is not listed here; see the ToME spell spoiler for that information.
The entries below for each god contain information under the following headings:
+(W@10) every 100 game turns, with a minimum of +1, if you are not praying, not in wilderness mode, and have done something other than resting during the last 100 game turns; no change otherwise.
-(4-(W@3)) every 300 game turns, with adjustments of -1 if you are praying and +(W@2) if you are of an elven race (Elf, Half-Elf, High-Elf, Dark-Elf or Wood-Elf), and a maximum of -1.
-(4-(W@3)) every 300 game turns, with a maximum of -1, if you are praying; no change otherwise.
-(5-(W@3)) every 400 game turns, with an adjustment of +2 if you are an Ent and a maximum of -1, if you are not in wilderness mode and have done something other than resting during the last 400 game turns; no change otherwise.
-(8-(W@6)) every 300 game turns, with adjustments of -1 if you are praying and -(5-(W@4)) if you are of an elven race (Elf, Half-Elf, High-Elf, Dark-Elf or Wood-Elf), and a maximum of -1.
Corrected damage bonus adjustments for Tulkas prayer, as noted by vfb
Typo, noted by user Maylith of the ToME forums.
"Updated" for 2.3.x. AFAICT, the described information did not change from 2.2.x.
Clarified that the damage bonus from Melkor hit-point sacrifice is based on current WIS.
Corrected Yavanna piety boost for charming animals.
Eru resurrection actually sets your piety to -200k rather than reducing it by 200k, as noted by user Elliot of the ToME forums.
Added notes on the effects of negative piety to Eru and Manwe entries.
CSS tweaks.
Added information about relic quest dungeons.
Mention the "hand of Tulkas" message explicitly as an indicator that the effect has occurred.
The "hand of Tulkas" melee bonus apparently only applies to weapon combat.
Initial release.
