A different kind of new powers thread

Let's get it over with off the top: I know where Suggestions and Ideas is. This is not a Suggestion (although it is an Idea, or rather many Ideas), and I'm posting it here because I'm looking for the input of people who think about powers that do exist in the game. What I'm trying to do is compile a list of power effects that could exist in the game, using only existing technology, but which no existing power currently does. I'll start off with some examples.

- An enemy-targeted damage toggle. We have enemy-targeting toggles, and we have damage aura toggles, but we don't have the ability to apply a damage aura to an enemy. I do not know whether it's possible for an enemy-targeting toggle to make a tohit check; an autohit damage toggle would, needless to say, be difficult to balance...
- An ability with a negative side effect of power de-boost on the caster. Share Pain and Absorb Pain do this to some extent by granting a -regen effect and 100% heal resistance, but I'm thinking of something that reduces buff and debuff strengths or decreases mez durations.
- A toggle that increases in strength over time. Implementable as a self-stacking toggle whose effect durations are significantly longer than its tick time. Would have to be interestingly constructed to make its slow ramp-up and lingering aftereffects more than just a curiosity.
- An aura toggle that applies a fixed buff, and a self debuff for each enemy in the aura. The user would wish to try to avoid melee...

It's worth noting that, even if a power seems unattractive as a player ability, it might be interesting as an NPC ability. That last one, in particular, would be interesting on an Arch-Villain.

I'm interested to see what else could be done, but isn't yet. Please remember: I am trying to find ideas that do not require new tech.

An auto self destruct power, scaling resists and damage buff as health declines, and a godmode that kills you as its crash.

I'm pretty sure none of that needs new tech and, at least in my (slightly biased) opinion, would be pretty freaking awesome.

A pretty similar list of ideas I had a while back. Some of the commenters had some pretty nifty stuff.

I've always like the idea of time manipulation as a support set, if only for this (conceptual) power:

A location AoE rez and +heal/end - Reverting the effects of time on your allies in a set area of space, resurrecting all those that have fallen and healing those on the brink of defeat. (possibly new tech, I know... but I REALLY like the idea of this power)

Control:Taunt (with additional debuff attached) - You are effectively protecting your teammates with that one, after all. Would work well with a -to hit, -range or -dmg debuff methinks.

Ranged:BU alternative - Instead of the longer-recharging self-buff, a Follow-Up style power for a ranged set would be rather interesting.

Control: Toggle Confuse - Unlike other confuses, this one would aggro on activation, be auto-hit, but only be mag 2, requiring time for each subsequent tick to overcome rank. Possibly a high end cost as well, to balance the auto-hit nature of the power.

Control/Blaster Secondary:PbAoE Placate - I'm actually not sure which AT would best be able to use this power (basically Smoke Flash), but the idea of a "lose all aggro" power seems like a good fit with some of the squishier ATs.

(Very) Short duration ally buffs. Stuff like Build Up or Moment of Glory, but applied to one of your teammates. The latter in particular would make a great "oh crap!" power for a support character.

a targetted to-hit set (with +acc/+rech/+to-hit) for things like follow-up, soul drain, etc

powers that cause increase or decrease in animation length (like snipe sets, but for other slow activating powers)

knock to a target attack (opposite knockback) with damage delt to target- wormhole is an ok example - but dont need a targetted "outlet." Or PBAoE as epicenter (tanker mass "come here" gravity well)

man I could go on, but no time...
