'''Spellcasting''' uses learned magic and mana to produce attacks, protections, information and travel effects. Omega has '''41 [[Draft:Spells|spells]]'''. Research, organizations and special rewards expand your repertoire; individual spell pages explain their targets, effects and practical uses. Monster magic follows [[Draft:Monster spellcasting|separate rules]].<ref>{{Source|spell.c|496|626}}; {{Source|spell.c|724|744}}; {{Source|command2.c|489|518}}.</ref>

__TOC__

== Learning spells ==
There is no requirement to join a magical profession before using a spell you know. The available routes differ in predictability and in what happens when the spell is already known.<ref>{{Source|command2.c|489|518}}.</ref>

<div class="omega-table-scroll" tabindex="0" role="region" aria-label="Spell learning routes">
{| class="wikitable"
! Route !! What it teaches !! If already known
|-
| [[Draft:Collegium Magii|Collegium research]], noncursed [[Draft:Scroll of spells|scroll of spells]], or [[Draft:Manaburst|manaburst]] remains || One randomly selected spell, subject to a research check || A successful attempt halves the current recorded cost, rounded up
|-
| Guild, religious and [[Draft:Rampart Explorers' Club|club]] rewards || The spell or spells specified by that reward || No cost reduction
|-
| Wish for '''Knowledge''' || One randomly selected spell, without the research check || Halves the recorded cost, rounded down, with a minimum of 1
|-
| Identified [[Draft:Kolwynia|Kolwynia]] || All 41 spells || No cost reduction
|}
</div>
Research includes already-known spells and does not let you choose a target. The Collegium accepts paid research from eligible outsiders as well as members; guild rewards instead give specific spells at particular ranks. A cursed scroll of spells removes knowledge rather than performing research. Kolwynia must be identified before use: using it unknown is fatal.<ref>{{Source|effect3.c|271|307}}; {{Source|guild2.c|279|445}}; {{Source|itemf1.c|120|129}}; {{Source|item.c|113|115}}; {{Source|effect1.c|613|620}}; {{Source|itemf3.c|292|307}}; {{Source|etc.c|120|225}}; {{Source|site1.c|235|260}}.</ref>

=== Research difficulty ===
Let ''D'' be the selected spell's current recorded cost, and ''T'' = 4 × Intelligence + 8 × character level. Research compares ''T'' with a uniformly selected integer from ''D'' through 5''D'' − 1, and succeeds only when ''T'' is larger.

{| class="wikitable"
! Condition !! Research success chance
|-
| T ≤ D || 0
|-
| D < T < 5D || (T − D) / (4D)
|-
| T ≥ 5D || 100%
|}
This chance applies '''after''' a spell has been selected from the 41 possibilities. It is not the chance of getting a particular desired spell. Learning a new spell grants 10D experience; making a known spell cheaper grants no experience. Research credit or a scroll is consumed even if the attempt fails. Positive blessing does not improve the research check.<ref>{{Source|effect3.c|271|307}}; {{Source|guild2.c|417|441}}; {{Source|itemf1.c|120|129}}.</ref>

For example, at Intelligence 15 and level 0, ''T'' is 60. A cost-10 spell is certain to pass the research check if selected; a cost-20 spell succeeds half the time. This is a learning calculation, '''not a spellcasting failure rate'''.

== Casting and targets ==
On a local map, press '''m''', type enough of a known spell's name to distinguish it, then press Enter. '''?''' lists matching known spells and their recorded mana costs. Escape at this spell-selection prompt cancels without spending mana or giving monsters the ordinary response to a command. The [[Draft:LOCUS|countryside]] command set has no direct spellcasting command.<ref>{{Source|command1.c|75|77}}; {{Source|command1.c|255|329}}; {{Source|spell.c|432|442}}; {{Source|spell.c|724|852}}; {{Source|command2.c|489|518}}.</ref>

[[Draft:Fear|Fear]] prevents casting. Otherwise, after a valid selection the game checks mana, subtracts the actual cost, and applies the spell. The common casting action takes 12 clock ticks; spell-specific sequences can take additional time. There is no additional general roll for Intelligence, armor or a magical school at this command stage. Individual spells can still have their own hit checks, resistance, failures or unsuitable targets; wishing has a concentration check of its own.<ref>{{Source|command2.c|489|518}}; {{Source|command1.c|75|77}}; {{Source|spell.c|8|25}}; {{Source|spell.c|194|235}}.</ref>

For a spell with a map target, move its cursor with the movement keys and confirm with '''.'''. An inventory-targeted spell instead asks for an accessible item. '''Mana is spent before these later prompts''': cancellation or an ineffective target does not automatically refund it. Some target routines also handle Escape incorrectly; [[Draft:Apportation (spell)|apportation]] and [[Draft:Clairvoyance (spell)|clairvoyance]] describe their specific limitations.<ref>{{Source|aux1.c|532|558}}; {{Source|command2.c|503|514}}; {{Source|effect1.c|501|517}}; {{Source|effect3.c|239|256}}; {{Source|effect3.c|547|559}}.</ref>

== Mana cost ==
The [[Draft:Spells#Spell list|spell list]] and information cards give each spell's '''initial base cost'''. Research and Knowledge wishes can reduce the cost recorded for your character. The spell-selection menu displays that recorded value, before the moon's modifier is applied.<ref>{{Source|spell.c|496|626}}; {{Source|spell.c|746|764}}; {{Source|effect3.c|295|298}}; {{Source|effect1.c|613|620}}.</ref>

{| class="wikitable"
! Lunar influence !! Actual cost for recorded cost D
|-
| Favorable || floor(D / 2)
|-
| Ordinary || D
|-
| Contrary || 2D
|}
A recorded cost of 3 therefore costs 1, 3 or 6 mana. A recorded cost of 1 can cost '''zero''' under favorable lunar influence: the casting adjustment has no minimum-one clamp.<ref>{{Source|command2.c|503|514}}.</ref>

The lunar check normally runs at midnight, using a 24-day phase cycle. Druid followers are favored at either half moon; sufficiently lawful characters (alignment greater than +10) are favored at full moon, and sufficiently chaotic ones (below -10) at new moon. Contrary influence applies to Druids at new or full moon, lawful characters at new moon, and chaotic characters at full moon, unless a favorable condition has already matched. Other cases are ordinary. These rules are evaluated at the lunar check, so a later alignment change is not an immediate recalculation.<ref>{{Source|aux2.c|284|305}}; {{Source|aux3.c|31|38}}; {{Source|scr.c|40|54}}.</ref>

=== Replenishing mana ===
The ordinary mana capacity is '''Power × (character level + 1)'''. This calculated capacity is not a hard cap on stored mana: some effects set the current amount above it.<ref>{{Source|char.c|172|175}}; {{Source|effect1.c|585|588}}; {{Source|itemf1.c|412|417}}.</ref>

{| class="wikitable"
! Method !! Result
|-
| Gain a character level || Refill to at least the new ordinary capacity, retaining a larger existing reserve
| [[Draft:Circle of Sorcerors|Circle's mana service]] || Refill to ordinary capacity; fee is 100 Au per character level, halved for members
| [[Draft:Powtab|Powtab]] || Set current mana to twice ordinary capacity
| A '''Power''' wish || Set current mana to ten times ordinary capacity
|}
These are different operations: an effect that sets a fixed multiple can reduce an even larger reserve, whereas the Circle and a level gain preserve excess mana. The normal minute, ten-minute and hourly recovery checks do not provide routine passive mana regeneration; the regeneration status actually spends mana to heal wounds. Use the relevant service or item page for its access conditions and risks.<ref>{{Source|aux2.c|451|478}}; {{Source|guild2.c|599|623}}; {{Source|itemf1.c|412|417}}; {{Source|effect1.c|585|588}}; {{Source|aux2.c|186|280}}; {{Source|aux2.c|340|447}}; {{Source|aux3.c|10|47}}.</ref>

== Losing spell knowledge ==
Learned spells are not expended simply by casting ordinary magic. Specific effects can remove them: a cursed [[Draft:Scroll of spells|scroll of spells]] forgets a known spell, a [[Draft:Village stones|village stone]] outcome can also do so, and Hecate's punishment for abandoning her can erase the whole repertoire. [[Draft:Spells#spell-wishing|Wishing]] forgets itself after reaching its wish effect, so it must be learned again. These are knowledge changes, distinct from running out of mana.<ref>{{Source|effect3.c|275|285}}; {{Source|aux3.c|1028|1035}}; {{Source|priest.c|179|196}}; {{Source|spell.c|8|25}}.</ref>

== Strategy ==
Seek predictable teaching when a particular spell is central to your plan. [[Draft:Identification (spell)|Identification]] has early religious and college routes; [[Draft:Object detection (spell)|object detection]] comes with thieves' membership; [[Draft:Return (spell)|Return]] comes with the Explorers' Club. Random research broadens your options but cannot guarantee the one emergency spell you lack.

Check the lunar situation and your remaining reserve before an expedition. Relearning an expensive spell can make a large practical difference, while repeated reductions of an already cheap one offer less. Cheap reconnaissance may save the mana and health a blind encounter would cost, but repeated surveys of an unchanged area are wasteful.

Keep an alternative for effects you may need while afraid or out of mana. A potion or charged item spends a different resource, and its effect parameters may differ from the similarly named spell. Consult the independent spell and item pages rather than assuming they are interchangeable.
