Yes, I think you are missing the fact that the eidolon can't use it's powerful hallowed stance AND attack in the same round. It has to choose between moving and attacking or going into the stance each round, since entering the stance is a standard action.
Basically, while the eidolon stands...
The enemies affected by "Come and Get It" must "shift 2" and end adjacent to the fighter, but prone creatures cannot shift (PHB errata), so they are not affected by the power.
In the case where forced movement forces a target into a hazard, the target can make an immediate saving throw and fall prone next to the hazard instead of going into it.
What if the target would rather go into the hazard than fall prone? Say it's a tiefling being pushed into a firepit when...
Re: Fortified armor
At epic levels, it basically grants immunity to fear effects that allow a saving throw, once per day. I don't think it's terribly overpowered...?
Shouldn't the Dragonclaw Armor daily power be an immediate reaction instead of immediate interrupt?
Power (Daily): Immediate Interrupt. Use this power
when another creature grabs you. You immediately
use the escape action with a +5 bonus to escape
the grab and deal 5 damage to the creature that...
I would like to echo the suggestion to scale the encounters instead of the PCs. However, if you are determined to do it....
A party of four is missing a couple of things as compared to a party of five:
One more PC for the monsters to wail on
The actions that one more PC would take
You...
It's not an opportunity attack though, it's a readied action. You can use a standard action to ready any type of action (standard, move, or minor) and hence use any power you like.
I agree that by the RAW the enemy should be able to finish his charge if he has the movement left, but the RAW...
What if the defender, who has readied an action, pushes the charging enemy one square (e.g., with Tide of Iron) when it moves adjacent? Can the enemy complete the charge if it has enough movement left?
