Scarlet Spider's trait is that lines of fire cannot be drawn to him when adjacent to walls or blocking terrain. Does that mean he can't be targeted for support if adjacent to one of those? Mainly asking for the sake of Alfred from 4 squares away.

Can people with flight freely go over hindering and elevation while indoors?

And do you take one or two damage from being knocked off of elevation?

I am not sure about Alfred. I would say no he could not target SS, but I would need to look at the exact wording of the power, and I am too lazy to do that.

Yes fliers and leap climbers can go over elevation and hindering indoors.

You take 2 damage from falling.

It says that lines of fire are blocked instead of stealth's only being blocked when its not your turn, so Alfred wouldn't be able to see him.

Yes, flight only would be blocked by indoor blocking terrain for movement

You take two, getting knocked back into a wall or blocking is 1 though

SUPPORT Give this character a power action and make an attack roll (that is not
an attack) against an adjacent friendly character as though making a close combat
attack. When using this power, neither this character nor the target can be adjacent
to an opposing character; ignore all combat value modifiers for this action. If the
attack roll succeeds, roll a d6 and subtract 2 from the result, minimum result 1. The
target is healed of damage equal to the result.

STEALTH SUIT: Lines of fire for an attack can't be drawn to Scarlet Spider if he is adjacent to a wall or blocking terrain.

FIELD MEDIC, STAGE TRAINING: Alfred Pennyworth can use Shape Change and Support; when he uses Support, he can treat friendly characters within 4 squares and line of fire as if they were adjacent and increases the damage healed by +1 for each action token on the target.

I say Alfred works

This is why it is good to quote powers. The earlier posters just thought that lines of fire to SS would be blocked, but the power actually says that lines of fire for attack is blocked.

This means that he can be Outwitted, Perplexed, Supported by Alfred, etc.

Heck, he can even be Pulse Waved, because the original LoF by PW is not for an attack and by the time the attack comes his power is ignored..

Are you sure about that? I'm pretty sure he can't be pulsewaved. Pulsewave has to draw a line of fire first. His power says lines of fire can't be drawn as long as he is adjacent to a wall or blocking terrain.

Actually all parts of Pulse Wave are an attack.
If you GIVE a COMBAT ACTION you have a COMBAT ATTACK.

Rulebook p. 9

This looks to be correct...when Alfred uses his SP to use support the LoF is not from an attack.

PW will NOT work against Scarlet Spider's Stealth Suit because when you are drawing LoF with PW it is an attack and if you cannot draw LoF to a character with PW then you cannot ignore any powers on that character that you could not draw the LoF.

He will be Targeted for Pulsewave, you Draw Lines of Fire first and when the attack is made all his game effects are ignored. It specifically says for attacks and yes pulse wave does consist of an attack but not until after drawing lines of fire.

The drawing of PW LoF before the attack roll is still an effect of a Combat Action which is only permitted when those effects of a Combat Attack are permitted.

MisterId is correct.

And, the Pulse Wave - Line of Fire wheel keeps turning.

Have you ruled that Skrulls and Shape Change get to ignore Pulse Wave? Because they dont!

These...are the Days of our Lives.

Yeah, support is not an attack, it just uses an attack roll
