For the portals: max didtance away from caster is 100 ft. In this range it can be opened anywhere Dmitri pleases, but cannot be in a pestilence, touching another object, or inside another player. Dmitri gains 1 charge in his savior arm evrytime it is hit with magic or a enchanted/magic weapon. He can open 2 portals per charge and stpre up to 2 charges, but can only ppen 2 portals at once. While the portald can open 100 feet from Dmitri, they must be atleast 70ft from eachother. The screens travel about 30ft.
The rocket pad can be attached to almost any solid surface, including flesh. So this can basically attach to something and send it flying at about 25fps. So Ex: User1 attaches the rocket pad to a weak pillar then presses the button. -TURN 2- the rocket pad activates and sends the pillar flying. Lightning scroll summons natural lightning from the nearest cloud to target location.
For the arm: when you say nullified AoE, here's an example: lets say a peice of paper(AoE atk) is flying at you, if you do an overhead slash(chop) with a knife(arm), it cuts it in half, now the width of the knife(arm) that touched the paper is destroyed, and the rest of it countinues to come at you. So its basically cutting the AoE in half, and taking a chunk the size of his arm out of it, making it a slightly smaller attack, reducing the damage done to Dmitri. (Bigger AoEs will be affected less while smaller ones will be effected more. I will however change this upon request.
Zip ties: yes they are actually zip ties like the ones used by bounty hunters and terrorists for makeshift handcuffs( i chose them cause its unexpected and there's no key.

I'm going to say the lightning from lightning scroll can only move on the same movement restrictions of 250 fps. There will have to be a short delay from when it is activated to when it strikes (a second or two at least) and starts from at least 200 feet above the opponent.

The portals are fine, but they cannot be placed within 10 feet of an opponent. There is too much potency in allowing that with a high speed ability, especially given it has defensive properties as well.

The arm is fine as long as it doesn't completely nullify AoE magic.
