Entropic Chaos 10% chance for heal

That's too bad I was hoping it would benefit the owner like the healing uniques rather than the caster.

I think he's trying to do something like slot it in Voltaic Sentinel and have the pet shoot, and the player get healed.

Didn't know VS took ranged sets I could sware i looked into it for this reason but saw that it only took pet sets but yes you hit the nail on the head

I have no idea if it does or not; I didn't check. But as others have said, if you can slot it, the proc will give the heal to the caster (ie, the pet). And since the pet is flagged as an invalid target, the proc will do nothing at all.

True it is effectively worthless, but if it were set to heal the owner it would be interesting

Yeah? Well, i beg to differ. If you have a lot of single target attacks and sets that give their best bonuses up to 5 pieces, and don't know what to put in the 6th slot, having a built in heal helps insanely, both inside and outside of a fight. Less downtime means you are clearing the content faster!

and how are you using a healing proc in a ranged damage set -outside- of a fight?

It's your opinion, which you're more than entitled to. But we'll have to agree to disagree. I've used it on a couple characters now and most of the time it tends to fire either when it's not needed (full health or near it) or it comes at a point where it's just not enough. It's a -very- minor heal. Maybe stacked with others it's useful, but it's by no means a reliable means of keeping health up.

You're more likely to get better bang for your buck slotting a damage proc to make sure you're not taking damage to begin with so you don't need to heal

I ran the calculations on it once. If you slot it in your tier 1 attack and fire it every 4 seconds for a minute it will proc an average of 1.5 times and heal you for about 90 health total. With base hit points for a blaster that's equivalent to 7% regeneration BUT if you have the plus HP accolades and a truer idea of how often you fire your tier 1 it works out to about .75 procs per minute.

That's 45 HP out of 1445 in a minute or about the equivalent of 3% more regen at the cost of a power slot. (ie: definitely not worth it). One thing worth noting though is that blasters can fire their tier 1 and 2 primary and their tier 1 secondary while mezzed. Sleep is a relatively common Mob mez power and sleeps break when the player is damaged, healed, or moved out of position. Since the EC proc is a heal and not regen it will occasionally fire and break a blaster out of sleep. The times that occurs is still relatively low and leaves the proc in the not really worth it range.

I presumed you could understand. By having more life in and after a fight, then the only outcome is that you have less downtime outside of a fight.

Knight, i find the proc pretty useful for my Huntsman, when he has no ways of green bar sustenance other than greens. When Single Shot has an animation of ~1 sec and an activation cycle of ~1-1.5 secs, while Burst has almost the same animation time for ~2-2.5secs cycle time, without going into the maths, the numbers that you have provided seem way better.

For some ATs and powersets, i can agree that this proc should not be very useful, especially if you have a heal of some sorts. But, depending on your build, it can be useful in its own way.

does it do any good there?

None at all.

The Entropic proc is OK in some powers as a little sop or if used in an entire chain as a bit more than that.

If you can fully saturate an attack chain with an average cast time of C and you spend P percent of the time fighting, then the equivalent +Reg is 10% * 5% / (1 + HP bonus pct) * 240s * P / C. (That's chance to proc times heal as a percentage of MaxHP times number of casts per 240s, which is the period it normally takes to Regen 100% of your MaxHP.) If you have, just for argument, 20% +HP, your average cast (in ArcanaSecs) is 1.8 and you spend 70% of the time fighting then the equivalent +Reg is around 40%.

I did a build like this for a FF/En Def (with only +6% HP) and achieved a +64% Equivalent in continuous fighting (i.e. plinking Targeting Drones), but in practice and using Force Bolt as a filler I managed +45%. Breaking it down from the logs I was getting the following +Reg equivalencies: Power Bolt 20.4%, Power Blast +11.7%, Power Burst +9.6% and Force Bolt +3.2% (limited by not being used unless nothing else was available).

In a soft-capped FF Def chasing +Reg (for the obvious reason) and +Rech (since the toon has passive defenses having a full attack chain is nice) it's not bad, but not great either. For ranged attackers who aren't tough enough for a bit of healing to make much difference or who have real self-heals, it's pretty irrelevant.

There's no such setting.

Procs can either affect the target of the power they're slotted into, or self. They can't be "set" to affect some other random entity nearby.

By putting it in Voltaic Sentinel (if it took the set, which others have pointed out that it doesn't), or Lightning Storm, you're effectively slotting it in all the pet's attacks. You aren't directly associated with any of those. The only place a proc could possibly fire on the "owner" is if the pet had a power that targeted you, like Demon's resist shield, or Dark Servant's heal.

Otherwise it might have a chance to heal you when you summon the pet, but that's about it.

I actually tried this in my Sonic/Ice blaster. I had the EC chance for heal in Shriek, Scream, and Shout. I also had the Sandman chance for heal in Sirens and in Frozen Aura (It checks per target in those powers and can proc multiple times per cast). Even in this most extreme case Aid Self was measurably better and I switched all the healing procs out when I respec'd.
