Description:
This D&D 5E extension allows you to easily roll a Wild Magic check
when using a spell by clicking or dragging the "spell cast" button next
to a spell on the actions tab of your character sheet.
It will only work for spells of 1st level or higher (customizable) and
only when you have the Wild Magic Surge feature on your character sheet.
It will roll a d20 and if the result is a 1 then it will automatically roll on the Wild Magic Surge table (PHB required).
The functionality is totally customizable from in-game. By changing
certain parts of the Wild Magic Surge feature's description on the
abilities tab of your character sheet you can change what table it rolls
on, what level spell triggers a check, what number or threshold needs
to be rolled on the check, and what die or dice are rolled for the
check.
Here is what can be customized in the feature's text (presented in usage statement syntax):
Code:
Once per turn, the DM can have you roll [a | an] (ROLL) immediately after you cast (a | an) [sorcerer | SCHOOL] (cantrip | spell of #[st|nd|rd|th] level) [or higher | or lower]. If you roll (a | an) # [or higher | or lower], roll on the (TABLE NAME) table to create a magical effect.
Code:
Once per turn, at the DM's discretion, you must make a DC # (ABILITY) saving throw immediately after you cast (a | an) [sorcerer | SCHOOL] (cantrip | spell of #[st|nd|rd|th] level) [or higher | or lower]. On a failure, roll on the (TABLE NAME) table to create a magical effect.
Code:
Once per turn, at the DM's discretion, you must make (a | an) (ABILITY) saving throw immediately after you cast (a | an) [sorcerer | SCHOOL] (cantrip | spell of #[st|nd|rd|th] level) [or higher | or lower]. The DC [for this [save | saving throw]] equals # [+|-] [[twice | half] the spell's level | your (ABILITY) modifier]. On a failure, roll on the (TABLE NAME) table to create a magical effect."[ ]" are optional terms, "( )" are required terms, choices are separated by a pipe " | ".
"#" in this case represents any number.
"SCHOOL" can be up to 8 comma-separated schools of magic (i.e. "transmutation, illusion, or necromancy" or just "evocation").
"ROLL" can be up to 3 different dice or values added or subtracted from each other (i.e. "2d6+2-1d4").
"ABILITY" must be the full name of an ability score (i.e. "Dexterity").
"TABLE NAME" is the name of the table you wish to roll on upon successfully triggering a surge. The table name is case-sensitive and must be loaded by the client that is casting the spell. (i.e. "Scroll Mishap")
Here are some example customizations of the feature that are correctly parsed.
They can be prefaced however you'd like ("Once per turn, at the DM's discretion, you...", "Whenever you...", etc) and the order of the sentences don't matter:
... roll a d20 immediately after you cast an evocation spell of 1st level or higher. If you roll a 1, roll on the Wild Magic Surge table to create a magical effect.
... When you cast a cantrip, roll 7d8. If you roll a 50 or higher, roll on the Drunk Effect table to create a magical effect.
... roll a d6 after casting a spell of 9th level. If you roll a 3 or
lower, roll on the Wizard Spells table to create a magical effect.
... roll 1d4+1d8+6 after casting an illusion or necromancy spell of 3rd
level or lower. If you roll an 8, roll on the Teleport Mishap table to
create a magical effect.
... must make a DC 15 Constitution saving throw after casting a spell of
1st level or higher. On a failure, roll on the Teleport Mishap table to
create a magical effect.
... must make a Dexterity saving throw after casting a spell of 2nd
level or higher. The DC equals 10 + half the spell's level. On a
failure, roll on the Teleport Mishap table to create a magical effect.

As of version 1.4.0 you can also specify the spell's level as the roll trigger or save DC:

Limitations:
This currently does not work for limited-use (checkbox) spells. It would be trivial to add this functionality, but it would require creating a copy of the entire power_counter.lua script just to add a single line of code to it, which would mean this extension would likely conflict with any future update to the 5E ruleset that changes the power_counter.lua script.
Compatibility:
This extension does not overwrite any base functionality, which means it should be future-proof and compatible with any other extension.
