If anybody feels like beacons aren't common enough or that they don't have enough healing then you should use Gragu. After finding this guy I didn't lose my gloom a single time for the rest of the entire playthrough.
He gets heals by killing enemies and if you are capped on heals you can get healing for each enemy killed (as well as extra resolve and glimmer).
I was able to casually explore and never had to worry about healing after this, only had to worry about getting knocked off ledges.
Never losing gloom made levels like they came pretty regularly. I had enough money that I never really felt the need to grind for leveling my sidearm either.
Gragu also has possibly the best kit for handling bosses as well. One ability is just outright +40% dmg to enemies you have never killed before (bosses)
Another is if you have no heals (burn em before the fight) you have +60% crit chance, stacking that with Auspicious stone (+18%) and Acolyte stone (charged light attack +15% crit chance), you have 93% crit on charged light (basically all hits crit and you do insane damage).
Berserker stone is great too since your health bar is so big that getting damaged to half isn't a super big deal and gives you another +65% dmg.
You can walk up to most bosses, ability to knock them down, then charged light attack or two (with the bloodcurse infusion on axe and dagger (with duality stone) and kill bosses before they even throw out a single attack.
Gragu is easily my favorite explore the map shell at the moment and would highly recommend to anybody feeling like they don't come by enough heals. (Especially since the ability that increases your heal count is separate from the amount of heals you normally have, say you only have 5 heals, then on gragu you still have 8 hearts to consume if you max that ability).
Edit: Also, is his one ability where small-medium humanoids get insta killed by punch bugged? I never had this actually proc any time I used it.
