Using Effect Features in Your Game

Effects in the 4E ruleset can be very complex, once you decide to take advantage of all of the functionality available. Many features provided in this section can be handled manually by calculations done by the players and GM, just like sitting around the gaming table. It is recommended that you slowly add effect capabilities to your game until the comfort level of you and your players has been reached.

While effects can be entered manually, the effects system was also designed to pull the effect information directly from the power description text by parsing the words. Just enter the text in the exact same format as the core rulebooks, or drop the powers from your own data modules.

The effect system was built to handle 90% of the situations. 4E can be a very complex game, as it is built using exception-based game design principles. With all the exceptions that are defined by powers, and the primary focus of the effects support was for the core rulebooks (PHB, DMG, MM); there will be some powers and effects that will not be able to be represented in the current version of the ruleset.

For example, effects that expire on the target's initiative will need to be adjusted manually, since applied effects always use the effect originator's initiative.

Campaign Effects

In addition to the basic label and visibility fields, the 4E ruleset adds a few more capabilities. The effect label can contain one or more modifiers or conditions that adjust rolls made by that CT actor. Additionally, an effect expenditure toggle button and duration fields

Combat Tracker

When an effect is applied to an actor in the combat tracker, in addition to the fields added in Campaign Effects, a few additional fields have been added.

Effect Label Features

In the 4E ruleset, conditions and modifiers can be embedded into the effect label in order to modify rolls made by the actor.

Each description, condition or modifier needs needs to be separated by a semi-colon within the effect label, and these are called effect components. Effect components that do not start with a modifier tag or a condition tag are treated as descriptive text only.

Special Components

Special Tag

Notes

IF: [condition OR conditional operator]

Ignores the remainder of the effect components within the effect label, unless the source actor has the specified condition.

IFT: [condition OR conditional operator]

Ignores the remainder of the effect components within the effect label, unless the opposing actor has the specified condition.

AFTER: [expiration]

Components after this tag are ignored. Components including and before this tag are removed when the effect expires, instead of removing the effect entirely. The expiration of the revised effect is set to the value of the expiration value, if any.

FAIL: [expiration]

Components after this tag are ignored. Components including and before this tag are removed when a saving throw against this effect fails. The expiration of the revised effect is set to the value of the expiration value, if any. Since the Failed Save clause only triggers for saving throws made at the end of a turn, this clause will only trigger on saving throws made using the auto-save option.

AURA

Denotes that the source power is an aura. If no expiration defined for effect, it will be set to "start" of current initiative when applied.

ZONE

Denotes that the source power has the zone keyword. If no expiration defined for effect, it will be set to "start" of current initiative when applied.

TRGT

When applied, denotes an effect that appears to be targeted to specific entities. In the combat track quick effect view, it is used to identify effect targets.

[expiration] = start, end, endnext, save, encounter

Conditional Operators

Not case-sensitive

Operator

Notes

ALIGN ([alignment])

If the creature indicated by the conditional effect has the given alignment, then this operator returns true.
Neutral is assumed for creatures where not specified.
True neutral checking is not supported due to necessary assumptions to make this feature work for majority of cases automatically.

SIZE ([size])
SIZE ([>= OR <= OR > OR < OR =][size])

If the conditional effect target is of the correct size or larger/smaller based on the size greater/less than operation, then this operator returns true.
Medium size is assumed for creatures where not specified.

TYPE ([creature type]*)

If the creature indicated by the conditional effect has the given creature type, then this operator returns true.
The humanoid creature type is assumed for creatures where not specified, and for PCs.

Wounded

If the conditional effect target has any wounds, then this operator returns true.

Bloodied

If the conditional effect target has wounds greater than or equal to half its hit points, then this operator returns true.

CUSTOM ()

Allows for testing of user created conditions, such as in the 'Hex' or 'Hunter's Mark' spells. The condition to be tested for is added in brackets after the CUSTOM keyword. Thus the syntax would be IF: CUSTOM(condition) or IFT: CUSTOM(condition). If the 'condition' is present on the target then the function will return true.

[alignment] = LG, LN, LE, NG, NE, CG, CN, CE, lawful, lawful good, lawful neutral, lawful evil, neutral good, neutral evil, chaotic, chaotic good, chaotic neutral, chaotic evil, good, evil
