{{flavour|Sif Muna the Loreminder is a contemplative but powerful deity, served by those who seek magical knowledge. Followers who triumph over their foes can call upon the Loreminder for magical power and the ability to cast spells beyond their magical training. The devout are rewarded with a supply of spellbooks taken directly from Sif Muna's legendary library.

Sif Muna grants followers the ability to rapidly restore their magical energy, and to forget spells at will, so as to learn new ones. Worshippers can call upon the Loreminder to help cast any spell they've discovered, even if it's well beyond their current magical training. Over time, devout followers will receive spellbooks containing a vast range of spells.

Sif Muna likes it when you kill living beings, you destroy the undead, you kill demons, you kill holy beings and you destroy nonliving beings.}}

==Gifts==
'''[[Piety|Piety level *****]]''':
:* '''[[Spell book]]s.''' Whenever you gain piety, if your gift timeout equals 0, you have a <code>75% * (piety - 122) / piety</code> chance to gain a spellbook.

Each spell book is either an ordinary spell book (24%), a Theme [[randart]] spell book (73%) or a Level randart spell book (2%).
*Ordinary spell books are the kind you find lying around the dungeon, and are weighted toward ones with spells you don't have in your other spell books.
*Theme randart spell books will contain several spells on a given theme (not necessarily a magic school). 
*Level randart spell books will contain several spells with a given level (up to your XL). A high Spellcasting skill will grant better artefact spellbooks. 

Sif Muna's randart books (both Theme and Level) will be larger than those found in the dungeon - they will be around 6 spells in size.<ref>{{source ref|0.29.1|randbook.cc|537}}</ref>

Sif Muna's [[gift timeout]] between books is dependent on the number of spells it has: the timeout equals <code> 9 + (spell_count * 6) + (2d19)/2</code> piety,<ref>{{source ref|0.29.1|religion.cc|1539}}</ref> where gaining piety will decrement this timeout. Note that when you have a gift timeout with Sif Muna, piety gain for all purposes except gifts is reduced.

==Punishments==
{{flavour|Sif Muna does not appreciate abandonment, and will call down fearful punishments on disloyal followers!

Those in Sif Muna's ill graces find the very forces of magic rebelling against them. They are confused and stupefied, their magical reserves drained, their enchantments unravelled. Casting spells, too, becomes unreliable - and even dangerous.}}

If you leave Sif Muna (voluntarily or not), your penance counter will be set to 50 (quite high!), but no immediate negative events will happen. Possible punishments include:
*30%: Temporary decrease in Intelligence by up to 20%
*30%: Confusion for 5-7 turns
*20%: All MP drained
*10%: Reduction of the remaining duration of all magic enchantments affecting you to 0 or 10 [[aut]]s (11 for [[Flight]]). This is identical to the effects of a [[potion of cancellation]].

Every time you cast a spell, there's a 5% chance that the failure rate will be increased by a percentage equal to your current penance. This is in addition to normal punishments, and will not reduce your penance.

==Strategy==
Sif Muna is the plain "magic god", without the focus on destructive ([[Vehumet]]) or necromantic ([[Kikubaaqudgha]]) sides of magic. Sif's spell gifts are weighted to contain spells you don't already have, so you'll eventually gain access to every spell.

Other than the spell books, the main draw of Sif is Channel Magic: a cheap ability that replenishes your MP. At 9 Invocations - a modest investment at mid game - Channel Magic recovers an average of 26 MP, 3-5 MP/turn. It continues to function even when retreating, attacking, or otherwise delaying your opponent ([[Hexes]], [[Mephitic Cloud]], etc.), making it a versatile effect. Channel Magic has a low piety cost, so don't be afraid to spam it. Divine Exegesis is also useful for accessing high-level utility spells, such as [[Death's Door]] and [[Dragon's Call]].

However, Sif faces stiff competition with other gods.
*Compared to the other "magic gods" (Vehumet and Kiku): Sif's book gifts come at 5* piety, which is very late. In addition, each book comes slowly, and is less predictable. In contrast, Vehumet's and Kiku's offer predictable, focused, and useful spells from 1*. Also, both gods offer more direct support in the art of killing, and do not require Invocations skill.
*Compared to gods in general: Sif has a relative lack of active abilities. Divine Exegesis costs a lot of piety and relies on your spell library. This leaves Channel Magic as the 'main' active, which, while useful, isn't a great ''escape'' tool.

Magical backgrounds obviously synergize with Sif, especially since the spell gifts only start at 5*.

===Tips & Tricks===
*Divine Exegesis will seem very weak and ''very'' expensive when you use it with a direct damage spell - their spellpower is likely too weak to matter. But Exegesis really shines with those with special effects: 
** High level [[Summoning]] and [[Forgecraft]] spells are great to use. [[Summon Horrible Things]] and [[Dragon's Call]] will create powerful allies even at low power, on or above the level of [[Trog]]'s Brothers in Arms. The lower spells can help greatly in the earlier end of the game, too.
** [[Shatter]] allows you to break stone walls. Other abilities that break stone walls, like [[Fedhas]]' Overgrowth, have similarly high piety costs.
** [[Death's Door]] and [[Borgnjor's Revivification]] are excellent last resorts, giving you time or giving you a costly max heal, respectively.
** [[Maxwell's Capacitive Coupling]] can take down the most lethal uniques and solo threats to your character in a few turns of channeling.
*Exegesis is still quite the expensive ability, but remember that Sif doesn't have many abilities to use piety on, and that Channeling can be activated long after you lose access to Exegesis. If you've gotten all the spells you need, there's little actual cost to the high piety cost.
*An [[amulet of faith]] early on will allow you to receive spellbooks much faster. Sif worshippers often struggle to get to 6* of piety, anyway, due to the 75% gift piety penalty. Meanwhile, an [[amulet of guardian spirit]] can make use of the 3-5 MP regeneration per turn, and channeling insures you won't run out of MP for actual casting.
*Sif can still have some use for heavy melee fighters, as Divine Exegesis offers some of the strongest panic buttons in the game. However, it's far from an ideal choice. Unless you have [[guardian spirit]], Sif only starts benefiting you at 4* piety... ''if'' you have some Invocations investment ''and'' happen to get a relevant spell.

When Sif Muna's altar is missing from the [[Ecumenical Temple]], keep a look out for wide hallways with blue floor tiles; when Sif's altar is not in Temple, it often has such a hallway preceding the altar proper. Regardless, like other altars, it is guaranteed to appear at least once between floors 2-10 of the main dungeon.

==History==
*Prior to [[0.31]], book gifts were less frequent at 6* piety, and more frequent at 5* piety.<ref>The gifting formula was changed from 50% to gift if <code>1d(piety) ≥ 102</code>, to 75% to gift if <code>1d(piety) ≥ 122</code>. So, technically, gifts were more frequent at 164 piety and below.</ref>
*In [[0.27]], Sif's gifting speed was made generally slower. Previous gift timeout was <code>39 + (2d19)/2</code>; it is now reliant on spells given. In addition, the chance to receive a gift after timeout=0 was reduced. This change was intended to increase Sif worshipper's [[piety]] (since gifts lower piety gain). Also, spellbooks themselves were adjusted: while Sif randarts remained the same size, regular books became smaller.
*Prior to [[0.27]], Sif could not gift the [[Book of Annihilations]], [[Grand Grimoire]], or [[Necronomicon]].
*Prior to [[0.24]], Channel Energy was a 3* ability. Divine Energy was a 1* ability, allowing users to cast without sufficient MP in exchange for a temporary -Cast status. Sif Muna granted protection from miscast effects, and offered less piety for kills, but gave piety for training magic skills.
*Prior to [[0.20]], [[Divinations]] [[miscast effects]] were directly used in Sif Muna's wrath; those replicated already existing wrath effects.
*Prior to [[0.19]], Divine Energy did not exist. Channel Energy was a 1* ability that instantly granted <code>1d(2+[Invocations/4])</code> MP at a <code>0 - piety/20 - floor(2 * Invocations)</code> failure rate, costing 100-200 [[hunger]]. Spellbook gifts began at 6*. Followers gained piety solely from training magic skills, and Sif disapproved destroying [[spellbook]]s, which was the only way to get under Sif's penance.
*Prior to [[0.15]], Sif Muna's wrath was able to force you to forget a spell.
