Guild Wars 2

Hello all.

I have just swapped to a bomb build that is easily exchangeable with grenades. My idea is to use bombs in PvE while I circle around the mobs, and then switch to grenades when I decide to mess a little in WvWvW. My current build is 30/20/0/20/0, since I really like using elixirs and the Vitallity bonus is very solid, together with Cleaning Formula 409.

Anyway, my question is about the trait number XI in Inventions, Elixir-Infused Bombs. It says that bomb explosions heal allies. I have tried to test it while in the dummies in PvP, but it’s hard to do so when you don’t really receive damage. What I really want to know is if anyone has had any success with that trait, and if it’s worth it to go that deep in Inventions for obtaining it.

Thanks in advance.

Without healing stat it heals very little, with around 1100 healing i think it heals 266ish, not very groundbreaking, something like guardian virtue, just you need to triger it with bombs.

Just an extra tip, on the northernmost side of island or western part there are npc that will also attack you. You can try there to test.

If you wanna do some support healing, better to use ElixirGun with Kit Refinement~Even without any healing it still does a constance 150HP per second at level 80 with large AOE….The trick is: switch to elixirgun give you 1st Super Elixir. After it depleted, switch to elixirgun again and use Super Elixit directly…Both effect has a 10 second duration and 20 second CD. If you just want some healing for yourself, get Backpack Regenerator from 20 Alchemy.

Yeah, I know there are better options for healing. I was using a condition damage build with P/P and the elixir gun, but I felt it was lacking in damage, so I switched to a Power/Precision bomb build. I was more interested in knowing if the healing bombs were worth the heavy speccing in Inventions or not, so that I can get some health back while also dealing decent damage.

As for Backpack Regenerator, I tried that, but it didn’t seem to work. I just didn’t get regeneration at all when I used it with any kits. Maybe it’s a bug.

@Emapudapus: Thank you very much for the help. This is more or less what I was trying to discover, how much the healing was. Since I don’t have the intention of speccing in Healing gear, I suppose it’d be a really small amount of healing, right? So I suppose it’s not worth the investiment, since I’d lose all that precision.

Backpack regenerator works. It doesn’t give you a regeneration boon, but a straight health regen when a kit is used.
Try using it, then get hurt by something.

Backback Regenerator works. Take fall damage and you’ll see the ticks per second. Nothing that’ll save you though. About 150 per tick.

Same with Infused Bombs. It’s about 150 as well. (give or take whatever your healing is)

I generally like more defensive low damage builds. My Guardian fits that perfectly. My Engineer…. let’s just say (to me) it feels like it lost a lot from its beta days. Weak defense and weak damage (compared to what I can do with other professions) no matter the stat/talent/skill specialization used.

I say try it for yourself. If you don’t like it, don’t stick it out thinking others made it work. It’s fairly mediocre. I use it (but eh, I’m just using it as placeholder until I find something more fitting for my build)

Well, that settles it then.
I was expecting to receive the Regeneration boon from tha trait, but now that you said it’s not the boon, just regeneration, it makes much more sense.

Thank you all once again for the helpfull responses. I believe I’ll stick with my build then, since 150 heal per tick isn’t worth losing all my Firearms traits and/or Alchemy ones!

Yes it is completely viable since bombs to alot of damage. Second highest in term of eng. It is about 170hps. I would do a hybrid and try get alot of power crit and crit damage. or even gear to switch out. Then use like turrets of healing kit.

Due to [Kit Refinement] you drop a Super Elixir every time you equip the Elixir Gun (~20s cooldown), then you can drop another Super Elixir (the healing of both Super Elixirs add up), switch to Bomb Kit and happily bomb away. The healing of the two Super Elixirs and the bombs combined with the Blind and slow from Bomb Kit #4 and #5 keeps you alive quite easily against most foes.
I’m not sure if [Forceful Explosives] also increases the healing AoE from [Elixir-Infused Bombs] but if it does it’s another must-have.

For more survivability you can go 20 points into Alchemy for the [Backpack Regenerator] but I don’t like that trait in this build because it doesn’t profit from Healing Power. Instead I put 30 points into Explosives for [Forceful Explosives], [Explosive Powder] and [Short Fuse]; it also allows me to get [Grenadier] in case I want to switch to Grenade Kit.

Cleric works best with this build because it gives Healing Power, Power and Toughness, the 25 points trait in Inventions adds 10% of your Healing Power to Power and you can choose a major Inventions trait which adds 5% of your Toughness to Power.

You dont need to keep using ElixirGun, just switch to it when needed for like 1 second. I was thinking about healing bomb like you do…But the disadvantage were much greater: you need to get close to target for DPS, that will draw you into melee ranged..I dont see how a bomb kit build would grant you enough survivability to get that close to the hot zone.

That is very interesting. I might test this. I completly overlooked that trait.

I run this as a dungeon build and melee love me.

Full exotic cleric. Bombs away.

For PvP you better be ready to do some shenanigins if you expect to do anything except wait for your friends to arrive.

You all talk as if you can only do one way of healing. I’m using a full support build with Kit refinement + elixir gun, elixir infused bombs, as well as constant huge AoE regeneration upkeep from heal turret. All of this COMBINED makes for great heal/support. You can’t always use bombs of course but with cleric gear and backpack regenerator you can hold out for a long time! Don’t forget various supporting effects you can get from runes, adding AoE fury and might or AoE regeneration!

From the “Elixir infused bombs formula” thread. You can try to decide for yourself if the healing gained is worth the stat/trait investment.

Here is the thread: https://forum-en.gw2archive.eu/forum/professions/engineer/Elixir-infused-bombs-formula/first#post1109000

Here is the relevant information:

Maullus

Elixir-Infused Bomb Heal = 0.1x + 145.6

Where x is Healing Power, and the character is level 80.

I couldn’t test this out anywhere but the Heart of the Mists, and I’m not saying it is a perfect model, but it appears to be accurate to within 1% for a level 80 character, within a range of healing power from 300 to 1400. I encourage folks to test it out beyond that range and see if it holds.

A few things I did notice:
1) The healing from Elixir-Infused bombs appears to be completely independent from the damage of those bombs.
2) The healing from Elixir-Infused bombs appears to be completely independent from the type of bomb used.
3) The healing from Elixir-Infused bombs is constant for a given x; that is, if you have x Healing Power, your heals from EIB will always be y amount, with no variation or range.

Hope that helps. Let me know if the model holds outside those conditions. Two things I’d like to test (but can’t, just yet):

1) For a level 80 character with Healing Power in excess of 1400, does the model hold?
2) For a non-level 80 character, would the following formula hold:

EIB Heal = 0.1x + 1.82y

Where x is Healing Power and y is level.

If you’re feeling inquisitive, check those out and let me know!

Edit: It occurs to me I didn’t give any actual data.

Healing Power :: EIB Heal
300 :: 176
465 :: 193
1109 :: 257
1223 :: 268
1388 :: 285

So, 165 Healing Power yields approximately 17 additional healing.
