I'm surprised they are still used by some.
And I'm glad you liked them.

Thank you a lot good fellow this mod will surely enhance the game massively :)

New update exchanges resurgence for a custom resurrecting spell (still granted at Champion level), which can be used once per battle at melee range. The new ability revives a perished friendly unit (But not enemy units, so no converting function for the sake of realism) and restores 50% of its health.

You might be glad to know that I'll update the mod in 15-20 minutes with the awaited change: a healing spell with 1 turn cooldown, and no use limitation!
I'm so glad I made it, and will mention the forum user who helped me achieve this.

I requested support on the forums to make a unique healing ability for the field medic, but I honestly doubt I'm gonna get any help, if not soon then even at all...
I'd like to keep it tier three.
As for the races yeah I'd like to give it to all races, but it takes a few times to copy paste and edit everything without making mistakes, so for now unless someone specifically requests a race I'll keep it the way it is. If you'd like another race in particular let me know.

Thats what I was saying, you get 3x heals during combat and then the unit isnt so good. I would look to the halfling race for ideas on the workshop here. There are some ingenious ideas modders have used to fill in support roles for halflings that give them battlefield uses beyond combat. Some of these ideas could be used by this unit. And I read you expanded this Field Medic to a couple of races, I was envisioning that this unit should be available to all races. Everyone should get a Field Medic. But if it's only going to get 3x heals a combat, I'd make it a tier 2 unit.

mod was updated to include Humans and Dwarves. Did some more testing to no avail, healing is still limited by a few times per battle.
Posted my request on the official modding forums to see if anyone can help.

But wouldn't regen just heal it to full health at each turn? It would still remain useless after a half dozen turns like you said. Although it gets a buff and debuff, and those should have him last more when he's at the fourth medal or so.
I accept your advice that his gold cost is too high, so I would like to improve it in other ways during combat without breaking its "thematic". Any ideas? I think increasing the attack would not fit well, and many buffs are magic related so don't fit either.

I asked for regen because its a tier 3 unit and it only has 3x healing abilities then becomes pretty useless in combat. I'm trying to justify its gold cost is all.

Thanks for your feedback. I'm afraid the healing machine is an oversight. It belongs to a property in the unit's settings which I should try to remove. However that may possible cause other issues so I'll see whether I can fix that or not.
As for regeneration, I haven't been able to play at all after finishing modding, beside a dozen minutes to make sure that the unit worked fine in combat. So, I can't tell whether it would really need regeneration or not but I can specify that two of its healing abilities also booster generation on the strategic map, so the unit should restore its health really, really fast. It also has faster additional regeneration by itself (not related to fast healing, its a 20% bonus or so). Have you found that they lose health too fast or you asked for this edit in order to give it more flavour?

Any thought about it being over/underpowered maybe?

I would presume that the dreadnought class gets an empire upgrade that allows support units to heal machines... which is why your unit doesnt have that... yet. Yes? Good unit otherwise, but I'm not sure if I'd make that unit a Tier 2 or 3. Maybe also give the unit Regeneration so it regens its hit points after the battle to full.
