__TOC__&lt;br /&gt;
&amp;lt;section begin=description /&amp;gt;&amp;lt;noinclude&amp;gt;&amp;#039;&amp;#039;&amp;#039;Tremors&amp;#039;&amp;#039;&amp;#039; causes&amp;lt;/noinclude&amp;gt;&amp;lt;includeonly&amp;gt;Causes&amp;lt;/includeonly&amp;gt; a disruption in the magical aura of an area, causing the area to begin shaking in what seems like a very minor earthquake, complete with aftershocks (except that it is an illusion).&amp;lt;section end=description /&amp;gt;  The strength of the initial tremor is randomly strong or weak, and the series of aftershocks progressively weaken in strength from the initial tremor.  As an [[area of effect]] spell, everyone outside of the caster&amp;#039;s group is subject to a warding roll to remain standing.  Any targets knocked down by Tremors will become [[Feeble]], suffering a penalty to their [[evade]] [[block]] [[parry]] (EBP)% by a base of 5% for 10 seconds.  The targets&amp;#039; EBP% penalty can be increased with training in [[Elemental Lore, Earth]], as described in detail [[#Lore Benefits|below]]. [[Prone]] targets that would have failed the knock-down roll also receive said penalty.&lt;br /&gt;
&lt;br /&gt;
Tremors can also be self-cast by preparing and then [[CHANNEL (verb)|channeling]] the spell. This will imbue the caster with 5 charges of Tremors, which can be increased with training in Elemental Lore, Earth. The caster can then {{boldmono|STOMP}} the ground, causing a single set of tremors at a cost of 5 mana and one charge (no aftershocks). Mana cost per charge can be reduced by training in [[#Mana Control Benefit|Elemental Mana Control]]. There is no round time for using such a charge. (The caster can also {{boldmono|TAP}} with a runestaff or quarterstaff in hand or {{boldmono|POUND}} with a maul to trigger the tremors.) This version will be somewhat weaker on average than the initial shaking of the open cast version, but stronger than the aftershocks.  The self-cast version of Tremors has a duration of 2 hours + ([[Wizard Base]] ranks * 60 seconds). Re-channeling Tremors refreshes both the duration and the number of charges.&lt;br /&gt;
&lt;br /&gt;
Although this spell looks similar to the [[Arcane]] spell [[Quake (1714)]], it does not affect adjacent rooms, and creatures do not receive [[roundtime]] when they fall.&lt;br /&gt;
&lt;br /&gt;
== Usage ==&lt;br /&gt;
*{{boldmono|[[PREP]] 909 {{!}} [[CAST]]}} or {{boldmono|[[INCANT]] 909}} to cast the [[open cast]] version of the spell&lt;br /&gt;
*{{boldmono|PREP 909 {{!}} [[CHANNEL]]}} to infuse a character with charges, which are later activated using:&lt;br /&gt;
::{| {{prettytable}} align=&amp;quot;center&amp;quot;&lt;br /&gt;
|Foot||{{mono|[[STOMP]]}}&lt;br /&gt;
|-&lt;br /&gt;
|Runestaff||{{mono|[[TAP]]}}&lt;br /&gt;
|-&lt;br /&gt;
|Heavy weapon?&amp;lt;br&amp;gt;(e.g. [[maul]])||{{mono|[[POUND]]}}&lt;br /&gt;
|}&lt;br /&gt;
:*These activators differ only in flavor messaging and are used alone without a target (i.e., just {{mono|TAP}}, not {{mono|TAP RUNESTAFF}})&lt;br /&gt;
&lt;br /&gt;
== Mana Control Benefit ==&lt;br /&gt;
Training in [[Elemental Mana Control]] reduces the mana cost of using a charge of the self-cast (channel) version of the spell by one each at 75 ranks and 150 ranks.&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot; style=&amp;quot;text-align:center;&amp;quot;&lt;br /&gt;
!style=&amp;quot;text-align:right&amp;quot;|Elemental Mana Control ranks||0||75||150&lt;br /&gt;
|-&lt;br /&gt;
|style=&amp;quot;text-align:right&amp;quot;|Self-cast charge activation mana cost||5||4||3&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
== Lore Benefits ==&lt;br /&gt;
Training in [[Elemental Lore, Earth]] has two benefits:&lt;br /&gt;
&lt;br /&gt;
===EBP Penalty===&lt;br /&gt;
Training in Earth Lore increases the target (EBP)% penalty from a base of 5 by seed 4 summation / 2.&lt;br /&gt;
{{equation box|{{math|Target EBP% Penalty {{=}} 5 + [[summation]]&amp;lt;sub&amp;gt;σ{{=}}4&amp;lt;/sub&amp;gt;(Earth Lore ranks) / 2}}}}&lt;br /&gt;
&amp;lt;section begin=Earth Lore Bonus/&amp;gt;&lt;br /&gt;
:{| class=&amp;quot;wikitable&amp;quot; style=&amp;quot;text-align:center;&amp;quot;&lt;br /&gt;
!align=&amp;quot;right&amp;quot;|Elemental Lore, Earth ranks||0||9||22||39||60||85||114||147||184||225&lt;br /&gt;
|-&lt;br /&gt;
|align=&amp;quot;right&amp;quot;|Target EBP% penalty||5||6||7||8||9||10||11||12||13||14&lt;br /&gt;
|}&lt;br /&gt;
&amp;lt;section end=Earth Lore Bonus/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Channel Charges===&lt;br /&gt;
Training in Earth Lore provides additional charges to the channel version from a base of 5 at 20, 50, 90, 140, and 200 ranks.&lt;br /&gt;
&amp;lt;section begin=Earth Lore Channel Bonus/&amp;gt;&lt;br /&gt;
:{| class=&amp;quot;wikitable&amp;quot; style=&amp;quot;text-align:center;&amp;quot;&lt;br /&gt;
!align=&amp;quot;right&amp;quot;|Elemental Lore, Earth ranks||0||20||50||90||140||200&lt;br /&gt;
|-&lt;br /&gt;
|align=&amp;quot;right&amp;quot;|Self-cast charges||5||6||7||8||9||10&lt;br /&gt;
|}&lt;br /&gt;
&amp;lt;section end=Earth Lore Channel Bonus/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Messaging ==&lt;br /&gt;
Initial channel:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;Faint ripples in the floor form beneath you for a moment.&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Prone creature affected by EBP effect:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;Creature bounces along the {floor/ground} as the tremors shake.&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the channeled self-cast version:&lt;br /&gt;
&lt;br /&gt;
{{boldmono|STOMP}}:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;As you stomp your foot sharply, the dirt shakes wildly!The ground begins to shake violently, making it hard to stand.&amp;lt;/pre&amp;gt;&lt;br /&gt;
{{boldmono|TAP}}:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;You tap your quarter staff on the dirt, unleashing a roiling wave of elemental power!The ground begins to shake violently, making it hard to stand.&amp;lt;/pre&amp;gt;&lt;br /&gt;
{{boldmono|POUND}}:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;With a dramatic swing, you pound your vultite maul into the floor!The ground begins to shake violently, making it hard to stand.&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Evade/block/Parry penalty applying to a prone target:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;The ground begins to shake violently, making it hard to stand.A black bear bounces along the dirt as the tremors shake.The ground stops shaking as quickly as it started.&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Channeled self-cast wearing off:&lt;br /&gt;
&amp;lt;pre{{log2|margin-right=27em}}&amp;gt;Faint ripples in the floor beneath you become apparent before quickly dissipating.&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The channeled self-cast messaging varies slightly based on indoor and outdoor usage.&lt;br /&gt;
