World Serpents Grasp
Whenever you hit a slowed or immobilized target with an attack, you can knock it prone
you are immobilized (among others)
The DM maintains that WSG does not trigger in the case. What say You?
This question is reminiscent of one previously answered:
The Rules Compendium, page 229:
No Degrees of Effect: Conditions don't have degrees of effect: either a creature has a condition or it doesn't
While the Battlemind is preventing the Immobilized condition, it is not preventing the Grabbed condition. Since we can't split the Grabbed condition up and only apply part of it, the Battlemind must stay Immobilized as well.
The same standard seems to apply: Restrained is not Immobilized and thus is not a valid condition.
The proper definition of Restrained does not include Immobilized or Slow in any way and therefore World Serpent's Grasp will not trigger.
A Restrained creature:
- can’t move, unless it teleports. It can’t even be pulled, pushed, or slid.
- takes a -2 penalty to attack rolls
- grants combat advantage.
The Rules Compendium (pg 233) goes on to note that
This condition is similar to the immobilized condition but it puts more restrictions on the creature's ability to attack or defend itself.
Based on this it would not be unreasonable to make a ruling that World Serpent's Grasp did affect restrained creatures, but it isn't supported within the rules as written and would be a house rule.
