{{Template:Skill|Mage|No|0|0|15|Variable|Spellbook, scrolls, reagents|No}}

Magery is the [[skills|skill]] that allows your character to cast [[spells]] out of your spellbook, using [[mana]] and [[reagents]], or to cast a spell from a [[scroll]], using [[mana]] only. There are 64 spells in UO, arranged into 8 Circles. The higher a spells circle, the more difficult it is to cast. Certain spells can be less or more effective, depending on the magery and [[Evaluate Intelligence]] skills. Magery is an [[intelligence]] based skill.

== Spell Success ==

[[File:fightingmages.jpg|right|thumb|200px|A couple of spell-casting mounted mages are fighting each other in [[Destard]].]]

To successfully cast a spell you do not only need the spell in your spellbook and reagents, or a scroll, you also need enough mana and the appropriate magery skill.

=== Casting from Scrolls ===

When casting a scroll, the game treats that scroll as if it were 2 spell Circles lower in order to determine chance of failure. (For example, if a player were to cast the 8th Circle spell Resurrection from a scroll in order to restore a fallen comrade to life, that player would have to be able to cast 6th Circle spells and would have a chance to cast that scroll equal to his success rate of castng spells of the 6th Circle.) The amount of Mana normally required for spells of the same Circle of the scroll is consumed during the casting of a scroll, regardless of success.

=====Example:=====

You have 80 magery skill. You cast Ressurection, an 8th-level spell. You have roughly 70.5% chance of success.
If successful, you lose 50 mana, and the scroll as well.

=====Formula:=====

Take the difference between your Magery skill and the minimum casting requirements for a spell 2 circles below the spell being cast, and multiply the result by the average percent gain of one skill point, which is 2%-3%, or 2.5%.

Let:

X = Player Skill

Z = Minimum Scroll Skill

Y = Percent Chance of Great Success

=====Y = (X-Z)*2.5%=====

=== Minimum magery requirements for casting spells ===
The number before the slash indicates the minimum Skill necessary to cast a spell of that particular Circle
(appr. 2% chance of success), while the number after the slash indicates the skill level necessary for a
99% chance of casting from that Circle.

{| class="wikitable" border="1" cellpadding="5" cellspacing="0" colspan="50" style="border-collapse:collapse;border:1px #000 solid" width="dynamic"

''*'' Every skill point from the minimum Skill necessary and beyond provides, approximately, an additional 2% to 3% chance of casting Spells of the this Circle, until the maximum of a 99% chance of success is reached. (Circles 1, 7 and 8 do not follow this guideline exactly).

=== Mana Requirements ===
[[File:statusbarold.png|right|thumb|200px|The (old-style) status-bar, showing [[Health]], [[Mana]] and [[Stamina]].]]
* First Circle: 4 mana
* Second Circle: 6 mana
* Third Circle: 9 mana
* Fourth Circle: 11 mana
* Fifth Circle: 15 mana
* Sixth Circle: 20 mana
* Seventh Circle: 40 mana
* Eighth Circle: 50 mana

== Gaining Magery ==
If you plan to train your magery with [[macro|macroing]], ensure you have enough [[gold]] available, or a steady income, to keep providing your training mage with enough reagents.

=== Gaining Magery without [[Resisting Spells]] ===

Training magery without Resisting Spells is less expensive and you can [[macro]] in town.

* 0-30 : Training from NPC Mage (costs 200-300 gold)
* 30-40 : Cast Third Circle
* 40-55 : Cast Fourth Circle
* 55-65 : Cast Fifth Circle
* 65-80 : Cast Sixth Circle
* 80-95 : Cast Seventh Circle
* 95-100 : Cast Seventh or Eighth Circle

=== Gaining Magery with [[Resisting Spells]] ===
(the ranges below apply to both skills)
* 0-30 : Train from NPC Mage* (costs 200-300 gold)
* 30-55 : Cast Fire Field* (1 black pearl, 1 spiders' silk, 1 sulfurous ash)
* 55-60 : Cast Lightning (1 sulfurous ash, 1 mandrake root)
* 60-82 : Cast Energy Bolt (1 black pearl, 1 nightshade)
* 82-100 : Cast Flamestrike (1 spiders' silk, 1 sulfurous ash)

''*'' Firefield can take you from 0 to 55 resist in about half an hour, just cast the spell and run end to end along the longest
distance of the field, this should be 5 tiles. If you started with magery at 50 you should also reach about the same magery
skill[55] by the time you're done. Then simply proceed with the above guide from Lighting Bolt.

=== Example Macros ===
'''Example macro 1'''
Pause: Mana >= 50
Restock Agent - 1
Wait for target
Target Self
Pause: .7secs
Cast Spell: Flamestrike
Wait for Target
Target Self
IF Mana <= 50
Useskill: Meditation
End IF
IF SysMessage = "Focus" (From Cannot focus your concentration)
Pause 10secs
Useskill: Meditation
End IF

This example macro uses a restock agent ([[Razor]] feature) to allow restocking from a bank box. Furthermore the use of the [[Meditation]] skill drastically increases the casting frequency and thus the training-speed. It is only suited to be used within a guard zone, where spells do no damage, otherwise it had to be extended by a [[hit-points]] check.

'''Example macro 2'''
// Restock Regs
Assistant.Macros.IfAction|50|0|5|Black Pearl
Assistant.Macros.HotKeyAction|0|Restock Agent-5
Assistant.Macros.WaitForTargetAction|30
Assistant.Macros.AbsoluteTargetAction|0|0|1076267748|2016|1113|14|3701
Assistant.Macros.PauseAction|00:00:02
Assistant.Macros.EndIfAction
Assistant.Macros.IfAction|50|0|5|Nightshade
Assistant.Macros.HotKeyAction|0|Restock Agent-5
Assistant.Macros.WaitForTargetAction|30
Assistant.Macros.AbsoluteTargetAction|0|0|1076267748|2016|1113|14|3701
Assistant.Macros.PauseAction|00:00:02
Assistant.Macros.EndIfAction
// Start casting at 30 mana
Assistant.Macros.IfAction|1|1|30
// And at least 50 hit points
Assistant.Macros.IfAction|0|1|50
Assistant.Macros.MacroCastSpellAction|42
Assistant.Macros.WaitForTargetAction|30
Assistant.Macros.HotKeyAction|1059|
Assistant.Macros.ElseAction
Assistant.Macros.HotKeyAction|3002039|
Assistant.Macros.WaitForTargetAction|30
Assistant.Macros.HotKeyAction|1059|
Assistant.Macros.EndIfAction
// Meditate if Mana lower than 30
Assistant.Macros.ElseAction
Assistant.Macros.HotKeyAction|1044106|
Assistant.Macros.PauseAction|00:00:00.5000000
Assistant.Macros.IfAction|4|0|meditative
Assistant.Macros.WaitForStatAction|1|1|30|3600
Assistant.Macros.ElseAction
Assistant.Macros.PauseAction|00:00:09.5000000
Assistant.Macros.EndIfAction
Assistant.Macros.EndIfAction

This macro example is a copy right out of the Razor Macro Textfile. The macro ensures, that the caster has enough hitpoints to survive the spell ([[Energy Bolt]] in this case). If the mana is too low, it starts meditating.

== Acquiring reagents ==
[[File:regsbag.png|right|thumb|200px|A bag filled with reagents: [[Black Pearl]], [[Blood Moss]], [[Garlic]], [[Ginseng]], [[Mandrake Root]], [[Nightshade]], [[Spiders' Silk]] and [[Sulfurous Ash]].]]
=== NPC vendors ===
The vendors in Alchemy- and Mageshops sell reagents of all kind. Buying reagents from NPC vendors is the most effective way to acquire them.
For prices check the article about [[Reagents]].

=== Loot ===
A couple of [[:Category:Creatures(Alphabetical_List)|monsters]] drop reagents as part of their loot. But usually this loot drops don't cover your reagents expenses for killing them. An exception is the use of [[provocation]] to kill the monsters, when the investment of reagents for offensive and defensive spells is minimal.

=== Wilderness ===
Reagents very sparsely grow in the wilderness. Thus, if you travel the wilderness, you might stumble upon the one or other reagent to increase your reagents stock. But the effort to solely look for reagents in the wilderness is by far not worth the invested time.
