Assurance Battle medicine

[Rinki23]

Have I understood this correctly?
I'm playing as a barbarian wielding a 2-handed weapon
I can take assurance medicine at 2nd level, which assures a 100% treat wounds success after 3rd level (10+2 for trained proficiency + 3 from level= 15; the basic DC for treat wounds).

Battle medicine at 4th level (which doesn't state that I need a hand free, just that I need to wear healers tools).

So I could heal myself for 2d8 HP once per day mid fight with a single action while raging and wielding a 2-handed weapon?

[Dr. Frank Funkelstein]

Battle Medicine needs a free hand.
"Requirements You're holding or wearing a healer's toolkit"
Healer's Toolkit: Hands 1 or 2
"If you wear your healer's toolkit, you can draw and replace them as part of the action that uses them"

you can, however, use a free action to release 1 hand, apply battle medicine and use 1 action to re-grip your weapon.

Also consider a bastard sword or other weapon that can switch between one and two handed use. But yeah, there'd been a long argument re: whether a hand was necessary and Paizo said yes, the PC needs a free hand for Battle Medicine.

Answering your main question, looks correct. Reaching fixed Medicine DCs is one of the main uses of the Assurance.

If someone (including you) is using Battle Medicine, consider Robust Health as well. Knocking that cooldown to be a 1/hour ability instead of a 1/day ability is nice.

I find it’s best to shoot for at least 2 battle medicine users in the party, with everyone having robust health so they can use it reliably. That provides plenty of in combat healing and great condition removal via paragon battle medicine.

You’re not in a great position to use battle medicine though, because of your two handed weapon. It’s best used on casters and other characters that can easily have a free hand. You should ask other members of your party to consider it, and if you still want to use it maybe swap to a one handed weapon (possibly with the two handed trait?).

If the party doesn’t have other battle medicine users (meaning it’s hard to justify robust health on everyone) you can make good use of it just for paragon battle medicine’s condition removal (while covering out of combat healing too!). If you’re doing that it’s less important to have robust health on everyone and a one handed weapon as you won’t be using it as often, but if your party doesn’t already have strong healing such as a healing font cleric, garden of healing animist, or multiple heal or soothe spell users who regularly prep a bunch, you’ll have issues.

Whatever you do don’t rely on health potions, they’ll suck your bank account dry and for less healing than the heal spell does (they’re bad enough at low levels but the high level ones are a joke compared to healing spells). The lowest level health potion works for getting people back on their feet but anything more is a waste (and so are the lowest level healing potions, soothing tonics fulfill that role much better).

As mentioned above, you need a free hand for Battle Medicine.

What you can use while raging and wielding a 2-handed weapon are focus spells like Lay on Hands or Life boost. The Heal spell works too BTW. Those spells do not have the Concentrate trait.

RAW you can also use Healer's gloves.

Godless healing is great for this too and it stacks with Robust Health for the number of HPs.

My unexpected discoveries: yes, they really don't have Concentrate!

But there's a catch:
2- and 3-action variants of Heal do have Concentrate.

Lay on hands will work fine on your barbarian. Can get it from blessed one or champion dedication (champion is probably better overall because then you can also get retributive strike).

Don’t bother with heal though, you can’t get it at high enough rank and can’t use the 2 action version (the good version) while raging.
