Maybe it's just a problem of number.
I can try this setting :
+25% size
+50% health
+50% damage
+50% armor
It only takes trial and error to get the right one.

The answer is still the same : I can't.
I've already explained why.
It's a pity, even though I imagine I can have Pet Angel of Death (Tyrael in Black).
But it's okay.

The main problem I have is how to design a skill that can summon a random minion.
Maybe it's not possible...
Hmm... I have 2 ideas:
- Have you ever tried the Wildlings class (in Variant Class). He has Passive skill (more precisely the Charge Bar skill) to summon Vanilla Pet as his Minion. Maybe you can take it from there.
- Make a Summon scroll for each Variant Pet, and after that give the Pet Dark Portal the ability to use Summon Variant Pet from the Pet Variant scroll randomly.
Hi
@Korzeam I have questions for Pet Dark Portal. What about animation when he acts when walking / running, when attacked by enemies, etc. Does it look good?
I'm afraid there will be a bit of a problem, because he's not the real Pet.
@Korzeam Anarch16sync made a similat portal skill for TL1CP that can summon units randomly. I will post the code when i get to my desk

There are not really animations because it's a particule effect and not a mesh, exactly like Wisp or Nether Wisp pets.
I probably can make it not attackable by enemies, not sure of that yet.

Thanks
@Phanjam !
I'm a little disapointing to see my idea is not original.

Never tried TL1CP, sorry.
I'm a little disappointed to see my idea is not original.
@Korzeam I encourage that it's not a matter of being the first to get the idea rather it's to be able to do it effectively at a later time.
Many ideas I have are not original however I keep editing my notes over the years and they become much better and more refined every time.
Often I've asked modders to edit and merge mod features together and they become a useful option for the community to use to improve their game.
I see this Pets Mod and your work with the same respect and appreciation!
If we can use a Skill (or a Pet that has a Skill) that allows the summoning from a random pool of minions then that would be so appreciated especially in a Pets Mod since TL1CP only did so on a Class it is far less restrictive if players want a more open mod that avoids adding large Class files into their game.
By the way, in the torchmodders discord LordNyriox made a suggestion for another variant pet - the "invisible pet".
What I actually said, is that for the "Lazarus Pack" mod, I ported over a vanilla TL1 pet, that was in the game files, but otherwise unused, called the "
Imaginary Pet".
This pet is both
invisible and
incapable of combat, and was designed to retain the Inventory and Merchant functionality that pets provide—without any other features.
I honestly feel that it was something of a "have your cake and eat it too" concept, providing the biggest benefit of a Pet (inventory and sales), without the pet interfering with your combat strategy (which pets make a habit of doing).
I'm a little disapointing to see my idea is not original. :-[
To be perfectly honest,
@Korzeam, when I find that one of my ideas is not truly original, I sigh in relief—because that means I do not have to do everything from scratch.
Instead, I can improve on the methods already discovered (see my "
Ultimate Respec Lite" mod, for an example), and improve the TL mod pool just that much more. ;}
@steffire3 and
@Lord Nyriox , Thanks for your comments.

I took a look at the alchemist skill and that's quite different from I want to do, but the idea is interesting.
To be honest I can't make it work for now, I have to continue searching.
Hi
@Korzeam I found a
Commanding Lord Class with skills "Death Summoner" that might be used for Pet Dark Portal.

And here are some other skills in some classes like Wildling (Skill Charge Bar) & Alchemist TL1CP (Skill Ember Rift).
Hi
@Korzeam I have an idea for Pet Dark Portal, rather than the Pet floating like Wisp pets or Nether, what if it is made he can teleport.

Or, it can be made like an Imaginary Pet that is not visible, and made only appear when he summoned a pet monster.
Hi
@Korzeam Can you adjust the size on several pet?- Diablo: need slightly reduced in size, so that it doesn't exceed the size of the player.
- Manticore & Alchemist: need slightly raised a little in size, so that so that it can match the player.
Noisy Pet:I found 1 more Pet which I think is quite noisy: Pet Mech Crawler
And I also found Guardian Siege Pet & Mana Guardian Pet are also still shouting.
Hi
@Korzeam If I look further on "Sturmbeon Caster & Armored Sturmbeon" Pet, I think that pets caused a lite vibration on the screen when walking. Can you fix it, it makes me dizzy. 😵
And I also found Guardian Siege Pet & Mana Guardian Pet are also still shouting.
Can you be more specific for that, I don't see what's wrong with these two pets.
When HP from Guardian Siege Pet & Mana Guardian Pet is dying or if he is hit by an enemy attack he will scream in pain.
What I did:
Let my pet fight the enemy alone and when he is attacked / HP in a dying state he will scream in pain.
